How to install a household air conditioner yourself. Useful information on DIY installation of air conditioners. Installation of the outdoor unit of the air conditioner

Air conditioning systems have long been transformed from luxury items in the offices and homes of oligarchs, into an affordable and virtually indispensable attribute of any room in which there are people. In addition, rooms are equipped with climatic systems in which equipment that is demanding on temperature conditions is installed. For example, server hardware.

The cost of a modern system is not so high, high-quality equipment can be purchased without any loans, within the framework of one salary. Taking into account the hot summer even beyond the Urals, we can say that at least 50% of the housing stock is equipped with air conditioners, and this figure is confidently moving towards 100%.

Since modern air conditioning systems are standardized, their installation is not particularly difficult. However, the cost of work increases costs by 30-50%. Therefore, thrifty owners practice installing an air conditioner with their own hands.

Possible limitations

There are no special requirements for such work, the rules for installing an air conditioner are usually regulated by the requirements of the SES (they may differ in each region). In addition, some municipalities may impose restrictions on aesthetics. For example, in historical centers, or in buildings that are classified as cultural heritage (or are historical monuments), local authorities may establish special rules for installing air conditioners on the facades of buildings. Often, such restrictions generally prohibit changing the appearance of an architectural structure. In such cases, climate systems with external modules are mounted on the roof (provided that they cannot be seen).

From a technical point of view, there are no additional difficulties, except that the line with freon will be significantly longer (which means the cost of installation work will increase). Another possible problem is the lack of protection from vandals and intruders (thieves). When the outdoor unit is located on the wall of a building, it is not available for external intervention.

Sometimes, literal fulfillment of such requirements leads to an aesthetic absurdity.

In some cases, the problem of organizing the climate (especially if it is an independent installation of the air conditioner) is solved by the selection of models:

window air conditioner does not change the appearance of the historical building so much;
floor systems are not visible from the outside at all.

We will consider all the ways how to install an air conditioner with our own hands, with the exception of the ducted climate system.

For reference: duct air conditioning assumes a separate hardware room with a powerful cooling system. Air ducts (ventilation system) diverge from this room to each apartment (office).

The safety requirements for the installation of outdoor units are also taken into account. Heavy equipment placed at a height of several tens of meters is a potential hazard if dropped. Therefore, the mounting brackets must be reliable.

The electrical wiring diagram for the air conditioner must comply with the Electrical Installation Rules (PUE), like any powerful electrical appliance. In addition, energy consumption cannot exceed the technical conditions (TU) of the input connection of the facility. Before purchasing, you need to calculate the total power of your electrical appliances, and compare the result with the restrictions set by the company that supplies the electricity. It is advisable that there is no need to turn off the climate system when turning on the boiler or iron. Otherwise, it can lead to overloads and emergencies.

Consider the main types of air conditioners, taking into account the peculiarities of installation and connection

Despite the wide variety of air conditioning systems, they can be divided into 3 main groups (excluding centralized ventilation and cooling systems):

Floor air conditioner (second name - mobile)

From a technical point of view, there should be no questions about how to install a floor-standing air conditioner. It is a self-contained device, usually on casters. Such a unit can be installed anywhere, having fulfilled the condition for the free space around the ventilation openings.

This type of air conditioner, by definition, is connected independently, since there is no installation work as a class. But there is one feature that is determined by the principle of operation of any cooling device.

The air conditioner does not generate cold out of nothing (otherwise it would be contrary to the Law of Conservation of Energy). It divides the mass of air into hot and cold. That is, the working stream becomes colder, and the waste stream becomes warmer. Let's take a refrigerator as an example. The generated cold remains inside, in a sealed enclosure. And the excess heat is discharged into the room, around the radiator on the back wall.

In the case of an air conditioner, these two streams will inevitably mix, maintaining an average room temperature. Therefore, the "excess" heat must be removed somewhere. For example, on the street. To do this, the floor-standing air conditioner has an air duct (sleeve), which must be connected to the outlet flange outside the room.

If the sleeve is simply brought out into the window, warm air will be drawn into the room, dramatically reducing efficiency. Therefore, the hole must be airtight.

The ideal option is the provided section in the window. If you order a double-glazed unit, and in the future plan to purchase a mobile air conditioner, stipulate this in the terms of reference. If this is not possible, you can install the diffuser in the window. Most owners of metal-plastic windows can object: modern frames do not have classic vents. For this, special inserts are provided in the opening full-size transoms.

It looks primitive, but it works 100%. The main thing is to provide a reliable lock for the position of the slightly open window.

In addition to the formation of "extra" warm air, any air conditioner has another by-product: condensation. The illustration shows the correct installation of a mobile air conditioner with your own hands:

Pay attention to the lower element - the condensate collection pan. The design assumes that the water will naturally evaporate, restoring the humidity in the room.

Information: when the warm room air passes through the honeycomb of the evaporator (cold radiator), moisture remains on the metal and flows into the pan. Not only is the air dehumidified, the liquid must be put somewhere.

In stationary air conditioners, a drain hose is provided through which condensate flows into the sewer or onto the street (everyone saw water dripping from the outdoor unit). But the mobile air conditioner stands on the floor and it is impossible to provide drainage. Therefore, the condition of the pallet requires constant monitoring. Otherwise, your parquet or carpet will be hopelessly damaged.

Advantages of a mobile air conditioner:

There is no concept of installation and assembly work.
Can be quickly installed in any room.
No wall drilling required.

Disadvantages:

Low efficiency.
Indoor noise.
Condensation must be monitored.

Window air conditioner (monoblock)

Just like the mobile one, this unit is made in one housing. Only the evaporator and condenser (hot part) are located on opposite sides of the unit. Correct installation assumes that the hot radiator is outside and the warm exhaust air does not enter the conditioned room. The illustration shows how the internal and external volumes are separated inside the housing.

The partition inside the monoblock, ideally, should be in the same plane with the wall in which the air conditioner is installed. If this installation is not possible, provide free space around the ventilation openings. Structurally, there are four of them:

drawing in air from the room to pass through the cooler;
outlet of cooled air into the room;
outside air intake for cooling the hot condenser;
outlet of heated air to the street.

These streams do not mix in the body, thanks to the same baffle. The condensate flows into a sump and is discharged from the body to the street.

Where to install the monoblock

This type is called windowed for a reason. A typical place for installation is a window or a special opening in a window frame. Of course, the ideal location is a separate opening in the wall of the building. However, from a technical point of view, it is quite difficult to fill such a niche. Therefore, you have to sacrifice the glazing area.

How to install a window air conditioner safely? If it is possible to change the configuration of the window, the best place is a sturdy window sill. Again, when replacing old windows with double-glazed windows, a deaf diffuser must be provided, which can be removed for the summer and returned to its place in winter. So the air conditioner will be more intact (room storage), and there will be no extra cracks in the cold season: it is quite difficult to ensure 100% tightness. Do not blow it out with foam.

In practice, most often monoblocks are installed in a window (fortunately, the dimensions can be selected with an accuracy of a centimeter). It's easy enough from a preparation point of view: there is no need to redo the window. However, the window air conditioner is quite heavy: in one case there is a compressor, two radiators (condenser and evaporator), as well as electric motors with fans. It weighs at least 15 kg, so installing a window air conditioner in an apartment with your own hands should ensure safety. Otherwise, you will be left without a window and without a comfortable climate.

It is necessary to mount a reliable support, at an angle of 1-2 degrees outward slope.

When installed in a window, dismantling for winter storage is also provided.

Perfect installation of a window block

In Western countries, the installation of sliding windows is practiced, in which the window is formed by vertical movement of the transom upward. This is the optimal place for the summer installation of a monoblock of the climate system. The window rises, a special frame with sliding curtains is installed in the opening.

The air conditioner is fixed on a horizontal platform, resting on the windowsill. Sliding curtains tightly cover the body, preventing outside air from entering the room. At the same time, the vent remains functional: you can raise it by opening air access when the monoblock is turned off.

Consider some of the nuances of installing window monoblocks:

Benefits of a window air conditioner:

Easy to install: no need to supervise the filling after installation.
Compact dimensions, while providing good performance.
The walls will remain intact.

Disadvantages:

Takes up a lot of space, partially covers the lighting area.
As a rule, dismantling is required for the winter.
Since the compressor is located in a common casing, the noise level is high.
Most often it is necessary to install it on the windowsill, so the flow of cold air is at the level of the human body.

Split systems

If, due to lack of space, the question arises: where to install the air conditioner in the apartment, take a closer look at the system with separate units (the so-called split systems). The compressor and evaporator are housed in the outdoor module, while the cooling system is inside. Thus, the aesthetics inside the apartment are ensured, and there is some freedom in placement.

The principle of operation of a split system is no different from any other air conditioner. The functional modules are simply spaced apart geographically and are interconnected by pipes for the movement of refrigerant (freon). When DIYers figure out how to independently install an air conditioner with separate units, this point raises the most questions. Monoblock systems are factory charged and sold ready-to-use. And the split system needs to be connected with pipes and provided with freon filling.

In fact, the outdoor unit comes pre-charged. Just in front of the fittings for connecting connecting pipes, there are taps, and they are closed. Once connected, they are opened and the refrigerant is distributed throughout the system, including the indoor unit.

However, correct installation involves pressure testing (tightness test under pressure) and evacuation before starting freon. That is, it is necessary to remove air from the piping system and the indoor unit. In addition, the length of the pipes may vary depending on the distance between the indoor and outdoor units. In some cases, the addition of freon is required before starting. Therefore, independent installation of a split system is most often accompanied by a call to the master at the final stage.

What kind of work can be saved (in the sense of independent execution)

Installation of the indoor module, of course. There is only one rule: it must be higher than the outer one, and it is located strictly horizontally. Then you need to drill holes to the outside for the two pipes, the drain hose and the mains control cable. With certain skills, this is not difficult.

And finally, the most "interesting" part of the job: installation of the outdoor module. Especially if you live on the 10th floor. However, industrial climbers and an elevating tower can be dispensed with. If the air conditioner is located under the window, installation can be performed from inside the apartment.

Any outdoor work must be performed using safety equipment.

Doing as shown in the picture below is extremely dangerous and strictly prohibited!

Also, when performing such work, an assistant is definitely needed. Compliance with safety measures is a priority!

After fixing the blocks in their places, a connection is made from each other with copper pipes for the refrigerant. To carry out these works, you will need a special tool:

With its help, tubes are cut, flared, chamfers are removed. Here you need to make a decision: perform the connection operations yourself (with the purchase of a tool), or pay the installer, saving on the installation of blocks. It doesn't matter if you just plug in the tubes and don't test the system (with evacuation), the cooling may not be effective.

How to connect the air conditioner to the mains? Compared to fixing blocks and starting freon, this is an easy task. Separate power line, RCD, circuit breaker, grounding. It is clear that many "masters" do without it. However, the requirements of the PUE must be fulfilled. Otherwise, you may get an electric shock.

Important! Before starting any type of air conditioner, make sure that the transport locks of the fans are removed.

When choosing a place for the indoor unit, you need to decide how to properly install the air conditioner in the bedroom or children's room? If cold air blows on the bed, the comfort will be replaced by a cold. Therefore, the module is placed near the window, across the bed so that the direct flow does not cross the vertical projection of the bed.

Important: the installation of an air conditioner in a wooden house, regardless of whether it is window or wall-mounted, does not provide for any special restrictions.

You just need to make sure that there is no fire hazard, and take into account the strength characteristics of the material. Any wiring that can pass through the wall must be laid in a steel pipe. Tubes and hoses are also laid using a sleeve (plastic can be used) so that the tree does not get damp from condensation.

Output

We have considered the typical issues of installation of climate control systems. Most of the work can be done independently, the call of the master is required only when refueling with freon. In addition to obvious savings, self-installation of the air conditioner gives confidence in the reliability of installation. You are in complete control of the process.

The principle of operation of the unit

All models of split systems on sale are built and operate according to the same principle. They consist of a compressor and evaporation unit. Special tubes are used to connect them. The outdoor unit is installed outside the wall.

Unit device

An evaporator is installed inside the room. More efficient and expensive models are equipped with several with a common compressor.

The principle of operation of the air conditioner at home:

1. High pressure refrigerant (freon) is supplied through a nozzle, the diameter of which corresponds to the outlet pipes.
2. It goes to the inner part of the evaporator, where it gradually expands, and after some time it completely boils. The generated steam actively absorbs heat.
3. In the process of absorption, condensate is certainly released in the form of water, which settles on the surface of the radiator.
4. Moisture is transferred into a reservoir and then discharged behind the walls of the house.

If the installation of the air conditioner is done professionally and correctly, the compressor will constantly pump out freon vapors from the inner chamber, while the internal pressure rises in parallel. As a result, the refrigerant heats up and converts it into a dense mist.

The refrigerant is redirected to the condensation chamber, where it is cooled by an integrated fan, transforming into liquid. In this state, it is sent to the evaporator (through the nozzle) and everything is closed in a circle.

note! If you install an air conditioner inside a room near a heating device, then the power consumption will increase significantly, and the device itself is likely to fail after a few months of operation..

Even ordinary dust can cause damage to the air conditioner. Wet cleaning is not only necessary, but also prescribed, and thorough, regular and thorough. Indoors, it is strictly forbidden to put any products or objects on the unit itself. You cannot cover it with a tablecloth either.

Scheme of work

Do-it-yourself installation of an air conditioner without fail presupposes the sealing of all connecting elements and joints, which will make it possible to neutralize the likelihood of refrigerant evaporation. Experts recommend placing the outdoor unit so that it is below the indoor unit in level. Standard installation of the air conditioner assumes the location of the outdoor unit in a cool place, in the shade.

The device and principle of operation of the air conditioner

Tools and preparations

Do-it-yourself installation of the air conditioner cannot be done without preliminary preparation of the tools:

electrical tester;
bicycle as well as vacuum pumps;
pipe cutter;
puncher;
indicator;
example;
pipe flaring kit.

Required tools for installation

This is just a basic set of components required for the installation of air conditioners. Additionally, a full coil of copper tubing is required (note that the ends must be rolled initially at the factory). Any visual defects (dents, scratches) are simply not acceptable.

note! Installation of air conditioning systems is impossible without making holes in the walls, damage to the external and internal finishes, so the work should be carried out in parallel with the repair.

Step-by-step instructions for installing the climate system

After purchasing a climatic unit and preparing the necessary tools, you can proceed to the main pool of work. The installation scheme is quite simple:

choosing a place for installing the unit.
installation of brackets on which the unit will be installed.
the installation of the external (outdoor) unit of the unit is initially carried out.
then the indoor unit and other elements of the system are mounted inside the facility.

note! In the process of performing the relevant work, it is extremely important to strictly observe safety standards, especially when it comes to the height of 2-3 floors. Knowing how to install the air conditioner yourself does not have to run counter to safety precautions.

The choice of a place for the installation of the unit is no less important measure than the purchase of the climatic device itself. Experts advise taking into account a number of requirements when choosing a place for an indoor unit:

distance from the side wall - from 30 cm;
distance from the ceiling - at least 15 cm;
to the nearest large object that interferes with the movement of air masses - from 150 cm.

Unit placement options

As for the placement of the outdoor unit, a balcony is considered an ideal place, but on condition that it is open. In the case of a glazed loggia, you can stop at the option of mounting on a fence, with a sufficient bearing capacity of this structure. For residents of the first and second floors, we recommend placing this part of the split system above the window, so as not to cause inconvenience and level the likelihood of theft.

note! In the case of a private house, no strict recommendations are provided.

Choosing a place for the unit

If there are several air conditioner units, then the minimum distance between them should be at least 1.5 m, optimal - 3 m. A number of manufacturers do not regulate this value and you can select it yourself. But it is better to refuse from the "sandwich" option, in which neighboring blocks are located with their backs to each other.

The distance between the 2 units inside the room is from 6 m. More is allowed, but in this case, refueling with refrigerant cannot be avoided. Better to invest in the specified value.

Where to install the air conditioner

Installation of brackets for air conditioning

Brackets for installing the unit

So where is the best place to install an air conditioner? - The climatic device is fixed in an unimpeded access zone. Installing an air conditioner on the balcony is the best option. This type of equipment requires periodic and quality maintenance.

Experts strongly recommend placing the outdoor unit on the north or east side. The installation of a window air conditioner is often carried out at the bottom of the balcony. This zone is considered the best, since it allows you to freely open the window and service the unit. The sequence of actions is simple:

1. The fixing points of the brackets are marked and marked with a level.
2. Holes are formed for the anchor bolts.
3. For communications, it is necessary to prepare a through hole, its diameter should be at least 8 cm. It is better to make mounting recesses and recesses in the space between adjacent bricks, this will not only simplify the work, but also make them visually neat.

Bracket dimensions

The brackets are installed in accordance with the preliminary marking, adjusting them in level and screwing in the anchor bolts. It is necessary to pay attention to the fact that there should be about 10 cm of free space between the base of the wall and the block of the air conditioning unit. The gaps must be carefully repaired. Having made sure of the reliability of the fastening of this block, the installation steps continue, but already inside the room.

ATTENTION! do not skimp on brackets.

Brackets for air conditioners. What is the difference?

Fixing the outdoor unit

Before fixing the outdoor unit, you need to make sure the structural reliability and strength of the wall. Large models can weigh more than 50 kg, and in some cases even more. Household climatic units weigh about 15 kg, and there are no problems with their fastening. Experts advise to provide a margin of safety for all fasteners and walls at least 2 times.

Advice! If you have outdoor insulation in your house, you should make sure that the brackets are not fixed to it, but to the wall itself.

In recent years, in the segment of private development, such material as aerated concrete has been especially popular. With all its positive qualities, it is not able to provide sufficient strength for the installation of an air conditioner. The issue is the same with the ventilated facade.

note! During the installation process, it is extremely important to ensure a horizontal level for the product, while you can use the building level. The slightest deviation is fraught with incorrect refrigerant circulation.

Correct fastening of the outdoor unit

the outdoor unit of the air conditioner should be blown by the wind from all directions (if possible);
it is better to place the body under a canopy;
residents of the upper floors of apartment buildings can place them directly on the roof;
the maximum length of the main line is 15 m, if this value is exceeded, then the cold losses increase.

Professionals pay close attention to the proper arrangement of the drain for condensate drainage. In accordance with the rules and regulations, this pipe must be connected to the sewer system. But our compatriots in the overwhelming majority neglect it, completely in vain.

The outdoor unit should be at least 10 cm away from the wall surface. It is required to ensure high-quality airflow to the unit. If you do not stand it, then the device may fail altogether. Remember that any activities related to the installation of the outdoor unit are fraught with high health risks, since this is a work at height.

Fixing the indoor unit

Professionals strictly forbid placing the indoor unit behind curtains, near electrical appliances, above the battery. Self-installation of the air conditioner in the indicated places is fraught with failure of the processor of the device. Having decided on the place, it is imperative to check the wall for the presence of other communication solutions (heating pipes, water supply, electrical wiring).

Fixing the indoor unit

Direct installation of a window air conditioner is possible only if there is a free area. First of all, a metal plate is mounted: at least 10 cm must be retreated from the ceiling, and about 7 cm from the base of the wall. The distances are marked with a pencil. Holes are made for the fasteners and the plate is screwed on securely.

Fixed plate for indoor unit

Further installation scheme involves fixing the indoor unit on the already attached plate. A parallel hole is made in the wall for laying a copper cable, condensate hoses, pipes, as well as electrical wiring. The standard includes all necessary products, solutions and elements.

Electrical connection

Electrical connection diagram

The indoor unit functions only with its own wiring, the cross-section of which must be at least 1.5 sq. mm. A prerequisite is the presence of an automatic shutdown, especially if it is the installation of industrial air conditioners. The wiring is connected to the shield only when it is completely laid: a yellow wire with a small green stripe is connected to the neutral wire.

note! In order to determine the phase and zero, it is most effective to use an indicator.

The rules for installing the air conditioner require the connection of individual units using insulated stranded wires, previously passed through a hole in the wall. Each climatic unit is supplied with an instruction, which clearly indicates the diagram and the sequence of wiring.

Answering the question of how to install the air conditioner correctly, professionals invariably state that the key to the success of this whole event depends on the quality and literacy of laying copper pipes. They are cut in such a way that there is a small margin (about 0.8-1 m) for bends.

Pipe laying

It is simply not possible to bend them, since dents, wrinkles will form, and the metal may crack at all.

note! Installation of industrial air conditioners, like household ones, involves the use of special pipe benders. They preserve the structural integrity of the tubes. For window air conditioners, this moment is the key to efficient operation.

Only then can the tubes be covered with polyurethane foam hoses, which play the role of thermal insulation. As for traditional foam rubber, it is completely unsuitable in this context, due to its short service life. Thread flanges are worn exclusively on the basis of pipe insulation.

Installation and installation of air conditioners is carried out with mandatory flaring, while the process itself requires utmost care in order to eliminate the risk of grooves and microcracks. Be that as it may, spare parts and the necessary tools should always be at hand. The nut should be placed easily on the rolling, but when tightening it is better to use a torque wrench, which eliminates the likelihood of squeezing out small particles from the treated area.

Further, it is enough to fix the corresponding pipeline at each fitting. At the drain branch, a small piece of pipe is attached in a reinforced casing (for such cases, it is better to use heat-shrinkable tubes).

Advice! An important component of a successful home air conditioner installation is the presence of a drainage pipe located as far as possible from the load-bearing walls.

The next step is to put pipes into the holes in the wall, while they should be placed as evenly as possible. At the wall, they fix the canvas with clamps. An air conditioner installed outside the home must be mounted as securely as possible. Small holes are filled with polyurethane foam. You can use a soapy solution to check the tightness.

System evacuation

To install air conditioners, it is necessary to evacuate the system. Even if the activities are carried out at home, you cannot do without this, since moisture and fine dust are removed within the framework of vacuuming. During the installation of the air conditioner, connections and threads are sealed, otherwise it will not be possible to remove air from the unit. A vacuum pump is used to evacuate air for 20-40 minutes.

Evacuation

After the installation of the air conditioner is completed, the refrigerant in the cylinder is supplied to the system. A small adapter is attached to it, and then a pressure gauge. The filling of the air conditioner reservoir is independently carried out taking into account and correcting for pressure. Upon completion of the process, the circuit breaker is activated, and the system goes into test mode.

note! Even circulation of cold air indicates that everything is done correctly. The climatic unit can be used for its intended purpose.

Outcomes

Now you know how to install the air conditioner yourself. This work is quite feasible. Naturally, this is not a simple and easy task. The key recommendation is to strictly adhere to the instructions and if any defects occur, they must be eliminated in a timely manner. In this case, the air conditioner will operate efficiently for a long time. Be sure to watch the video on installing the air conditioner from A to Z.

Today we will discuss how to install the air conditioner with our own hands, it concerns the outdoor unit. Wait a little longer to call the climber, let's try not to fall out of the window. In fact, the air conditioner is being started using the stock accumulated by the system. Freon is initially accumulated by the external unit; after docking, the refrigerant is released. It is advisable to measure the temperature difference between the boiling point and the vapor of the low pressure side of the air conditioner compressor. The collector contains a scale for different brands of freons, supplied with the necessary information (the first parameter). The second is measured with your own hands ... Let's see how to install the air conditioner yourself.

Sequence of actions when installing the air conditioner

The critical part is determined by the location of the outdoor unit. Enthusiasts suggest equipping balconies with a box. Avoid installing the air conditioner, forgetting to assess the future performance. The length of the air conditioner lines is fixed. Mount copper pipes as much as the kit gives. From the difference, the channel pressure will slightly change, leading to the air conditioner going beyond the permissible modes:

Too low freon pressure does not withstand operating temperatures. The cooling process of the air conditioning compressor will be disrupted, causing increased wear on the unit.
Excessively high pressure raises the boiling point of freon. Part of the liquid phase will enter the air conditioner compressor, causing breakdown.

Masters monitor the freon pressure of the air conditioner circuit sometimes on the barometer scale, a more accurate temperature method. A collector is connected to the inlet of the external unit on the low pressure side (thick tube), the boiling point is found on the scale with risks. It is enough to measure the vapor temperature (tube temperature), concluding that the freon mass is excessive / insufficient. Professional craftsmen cut the tubes with a tool, roll the ends, after putting on the nuts, perform installation on site. If necessary, the copper wiring is extended by soldering.

Couplings are used - pipes of a larger diameter. A flaring tool is available to a specific length. The processed end of the tube is put on the other.

The solder seam comes out alone, doubling the strength of the connection. It is clear that without a tool, it will not work to flare the tube, the method of couplings is more suitable for ordinary people. Before soldering, the ends are cleaned, leveled to avoid foreign bodies entering the inside that impede the operation of the compressor (the equipment will simply break if a solid gets inside).

The tubes begin to lead with the inner block in the direction of the outer, punching walls in places. The points of the joints isolate (as well as the path of movement of freon). The drain tube, the power wire of the external unit (through the internal one) go in one bundle. Copper pipes are simply screwed in with a predetermined tightness, drainage pipes are overlapped, wrapped with plumbing tape (fumilent, fumlent). The electrical wire is mounted in place, by the lugs-terminals. The device is powerful, it is not recommended to plug the air conditioner into a typical outlet. They lay the wire of the 230 volt network distribution panel, carry out the installation using standard techniques. On the block. Try to avoid twists.

Copper pipes are connected to the external unit with nuts according to the thickness. The high pressure side is thinner. Find the service port on the low pressure side by looking for a thick tube. Let's take a closer look at the joint. In the lower part of the left side of the external block, there are a pair of L-shaped pipes. At the end of each there is a cover (hex key) that hides the bronze fittings (faucet). In the initial state, both branch pipes are closed; freon is collected inside the external block.

Vacuum tool

Evacuate the system before refueling. The step frees the freon tract from moisture and air. Evacuation is carried out by a compressor (vacuum pump) until the pressure drops to zero. Then the device will work for a while (5 minutes), guaranteed to remove condensate, if it is stuck in the evaporator. Then it is necessary to turn off the manifold tap. It's time to carefully release the freon. The valve of the thin tube of the outdoor unit opens first, then the valve of the thick one. The pressure should gradually equalize, we start the compressor. An assessment is made of the sufficiency of the amount of freon. The difference between the boiling point and the vapor temperature is within the range of 5-8 degrees Celsius. The difference is less than acceptable - there is too much refrigerant. Exceeding 8 degrees requires adding the required amount from the cylinder, controlling the temperature.

In a two-position manifold, a container with freon is connected to the place of the pump. Moreover, you need to bleed the air from the connecting tube by opening the right manifold valve for a second. Then start refueling. Rosenberger mechanics say: it is useful to turn the cylinder upside down, unless the freon is R22. Soldering is carried out with a silver alloy of at least 5% content, with another suitable flux. Tin with copper, any other metal, form an electrochemical pair, while operating, avoid water ingress.

Filling the air conditioner with freon

As in a water heater tank - the corrosion process will begin. Therefore, leaks will be possible. Not dangerous, as in the gas industry, you just have to call the service group to refuel. Some freons are poisonous, others destroy the ozone layer. If there is a leak, the concentration does not reach explosive.

Installation of the outdoor unit of the air conditioner

Throwing aside the climbers, the lone heroes, it will be difficult for an ordinary layman to install an air conditioner on a wall. Let's take a look. A typical outdoor unit enters in the middle of a typical high-rise window, from any frame it is 30 cm to the bracket. A short distance by the standards of an adult. Without effort, a man will be able to pierce the wall with a puncher, hammer in anchors. Difficulty can be caused by chemical anchors, under which it is necessary to thoroughly clean the hole, preceding the laying of the adhesive.

However, the techniques are rarely used. More commonly used are traditional steel anchors in quantities of four or more. The bracket is simple, reminiscent of the letter G. On the shelves of two parts, the external unit of the air conditioner is attached with four bolts - two on each side. It is important to get the mounts, then fears can be discarded. Similarly, the process of docking and starting the system is carried out from the left window. Better than bending over with the key, kissing the windowsill, risking falling out.

Outdoor unit installation type

The now standard installation under the window has one significant advantage: it is relatively easy to mount the external unit of the air conditioner. It is difficult to tighten the bolts (stretch far), opening / closing the valves is a problem. Consequently, removing rusted fasteners is not easy. Leaning out without insurance is dangerous. In the case of installation between windows, the first place in complexity is occupied by the process of installing the external unit on the brackets. Residents want to cool the apartment in the summertime, a stack of external blocks is piled on top.

It is easier to install an air conditioner on the balcony, nowhere in the legislation can you find a prohibition. There are rumors - because the authorities were too lazy to create an information and legal portal - it is forbidden to put an external block on a heated loggia! There are three windows, one right in front of the equipment, it seems like you can put it. We apologize for the legal confusion. Apparently, the authorities think that since ignorance of the law does not absolve one from responsibility, there is absolutely no need to educate the people. Maybe a fool will break it - it will be possible to file an administrative case. Don't believe me? Try to find in a search engine the number of the law governing the installation, excluding the general words about the need for approval (on the facade). The authors dropped out after half an hour of research.

There was definitely a law, there are rumors: the text was canceled in 2013, members of the forum are wondering what would be non-compliant. It is useless to ask lawyers, lawyers shrug their shoulders. The regulatory framework of the city of Moscow is more pleasing: there are documents, but the first edition. Understanding, following the amendments, where to add new lines, it is incredibly difficult to read a fragment. Therefore, let's say: in 2007, residents were obliged to coordinate the installation of any engineering equipment on the facades, God knows what next. Therefore, the question of how to install an air conditioner with your own hands would start with a regulatory framework, then go through the options. Note: the installer is not interested at all, the owner of the home is responsible.

We hope we have clarified how to install the air conditioner yourself. We recommend that the most zealous readers visit the mosopen.ru website on their own. The confusion and confusion in the interpretation of legal terms makes one wonder that legitimacy exists.

Step-by-step video of installing the air conditioner

The cost of installing an air conditioner is high. Grows parallel to power. The question was discussed in detail, how the purpose of the mysterious letters that dotted the tables of the installation firms, today we will see what the workers are doing, that installing the air conditioner with their own hands becomes a complicated and difficult business from a financial point of view. There is a difference between the models of different firms, but insignificant. That is why the installation of the Mitsubishi air conditioner is not much different from the Samsung. It is clear that Koreans are now promoting inverter quiet, durable motors, you should first look at the warranty. Today, washing machines and refrigerators are equipped with a 10-year warranty card. Long term, for our reasons, a good air conditioner cools longer: paid more, the cost of installation bites.

Car air conditioner

We will decide where to install the air conditioner. As the first step, Samsung experts recommend ... to check the marking of the outdoor, outdoor units, boxes for coincidence. If the wrong unit was placed by mistake, the installation of the air conditioner cannot be started. The indoor unit is mounted on a special oversized plate. However, there were some nuances here:

Floor-standing indoor units are deprived of the right to bear the name, since they are hanging. The distance to the parquet should not exceed 15 cm. The mounting plate (bracket attachment) changes its appearance, from a solid size of a steel substrate it becomes a strip. Mainly the upper edge of the indoor unit of the air conditioner is attached.
Cassette indoor units of air conditioners are popular due to their ability to be embedded in a false ceiling. It is necessary to calculate the strength of the overlap so as not to kill employees, to provide the necessary indents, an aesthetic appearance. Fastening is carried out with four threaded pins, driven deeper into the concrete on the nuts through shock-absorbing washers. If the dampers are removed, allow the upper wall of the indoor unit of the air conditioner to come into contact with the ceiling, the level of vibration, noise will increase, negatively affecting the working, living atmosphere, it is simply prohibited by laws and standards to make a lot of noise. The topic of fan damping devices was raised, those who wish will study the required section.

The indoor unit hangs over your head. Calculating the height of the air conditioner is useless. The only thing is to maintain the distance indicated by the instructions from the walls, ceiling. When installing the base plate, a building level is used to correctly maintain the corners. It is especially important to strengthen the pins of the cassette unit, to position the unit strictly horizontally. Fixation in the latter case is carried out with locknuts. The installation process of the wall-mounted indoor unit does not cause any problems. The body is simply hung on the prepared bracket.

Air conditioner communications

Indoor, outdoor units are connected by a bundle of communications, including:

The cable is pulled from the shield of the external unit to the shield of the internal one, which has located the labeled terminals. Each ear is put on a phase, ground, neutral. The cable is used for outdoor use, it is more expensive than the usual PVA. There is one earthing conductor. It was explained that the neutral wire, the ground are different things, avoid confusion, change places, close your eyes would be the wrong tactic. When conducting three phases, purchase a 5 core cable. The output currents are added, the nuance is taken into account when choosing a wire. If one core is thicker, zero (not earth) was found. We take into account the nuances when choosing a circuit breaker, typical fuses will prevent an accident.

As for the electrics of air conditioners, typical ears are used. If it is necessary to install a wire of non-standard length, we will increase it ourselves. The copper tube comes complete, the ends are cut off, the chamfer is removed from the inside with a suitable tool. Fastening is carried out with nuts. To flare the end, a special tool is used to bend the tube outward with a cone. After the nuts are screwed coaxially, tightened with a wrench. Use the handy tool. Take an adjustable wrench, avoid gas wrenches. A typical installation of an air conditioner does not provide any seals, the tightening force is indicated by the manual. Each tube is jacketed to prevent heat exchange, both are wound together with the wire, drain tube. Copper tubes of unequal diameter, simplifying installation.

On the reverse side of the indoor unit there are nozzles, each of its own diameter, closed with plugs. Please note: when pulling communications through the walls, the nuts dressed on flared tubes are closed with plastic inserts so that the plaster does not cram inside. The drainage tube is simply joined in tension, wrapped on top with insulating tape. Do-it-yourself installation of the air conditioner continues outside, where a bulky unit sometimes has to be erected on a support high above the ground. Please note: although there is a manual, installation will require a project. The work is carried out to make sure that the walls will withstand the load, in theory. In practice, the designer just cuts the loot.

The distance between the indoor and outdoor unit along the communications does not exceed 5 meters. Departure from the rule translates editing into the category of non-standard, adding cost. The maximum length of communications is indicated by the passport. As planned, the drainage goes down to the ground, copper pipes reach the outdoor unit. In practice, they forget to do it, so the condensate irrigates the underlying objects.

Refueling the air conditioner

There are rumors: there is sometimes freon inside the outdoor unit ... I wanted more confidence, the installation manual gives an exhaustive answer, the taps are tightly closed ...

The procedure for refueling the air conditioner:

First, inspect for correct installation. Both branch pipes have taps hidden under the screw caps; avoid touching the fittings. One connector (usually the thick one) has an inlet for the refueling manifold. We attach the left hose, crown the central one with a vacuum pump.
Opening the left valve, pump out the air, wait until the arrow shows 0, continue for 15 minutes. Let's close the tap. Instead of a pump, we connect a freon cylinder to fill the air conditioner.
It is time to remove the end valve covers of the outdoor unit. Under them there are nests, often of a hexagonal shape, unscrewed with a special key (reminiscent of the fittings of a folding bicycle made in the USSR). To install the air conditioner yourself, turn the taps to the maximum. Keeping the position, we will operate, carefully return the covers.
Open the left manifold valve, filling bottle valve. Refueling is carried out, guided by the mass. Although there are schemes (mentioned above) that measure the temperature difference by releasing freon from the external unit into the circuit.

Refueling is over, the calculation of the capacity of the air conditioner, the conversation was conducted by the portal. A representative of a small class of devices demonstrating an efficiency higher than 1 (much).

GOST 26963

Get started with permission. The devices that stick around the wall of the house are coordinated with numerous organizations. First of all, the owner. A person has the right to sell an apartment, not an apartment building; many people live. Before installing the air conditioner, you will need to obtain a permit, (before approval) take care of the project to get a certified organization. The work deprived of documentation is illegal. Do you like the layout? A horror story went around some regions: the brigades authorized by the administration iron the streets, dismantling the illegally installed equipment. If the air conditioner is installed secretly, a tower will arrive and the product will be removed. We find it difficult to describe the procedure for returning, try hard lawyers. In the country, some people are more equal than others, so avoid looking up to your neighbors ...

According to GOST 26963, the installation of the air conditioner is limited by the scope of the operating instructions. Simple, isn't it? You take it, put it on, but a bunch of regulations prohibiting the installation of an air conditioner (as well as other equipment) are hushed up:

if the house is an architectural monument;
if the building decorates the main street with a facade;
if there is an artistic value of the building ...

The list of restrictions is long, we are ashamed to describe the difficulties, we recommend that you simply puzzle the local administration. It is required to spoil the wall of a high-rise building - it will be enough to obtain permission from the HOA. For example, an antenna requires the consent of 100% of the inhabitants of the house ... just. You cannot do without permission on someone else's property. In practice, there are few people who pay attention.

Now power. You know, in the firms involved in the installation, the value is marked with numbers in the range 07-30. Moreover, an increase in the number raises the cost of work to the heavens. Why people are interested in installing the air conditioner on their own. For example, for newly-made owners of 30 models, the installer's service will be 20,000 rubles. It is clear that a rare dude wants to pay the amount, or wants to know the direction of money flowing away. First, the power. Most bite their elbows powerlessly, trying to correctly calculate the parameter.

Fitter 90 lvl

There are online calculators, ready-made Excel programs that allow you to get the desired number by entering a couple of numbers. The size of the room, the number of printers, copiers, and other household appliances. The beauty of Excel is the ability to embellish the calculations with custom values by setting the cardinality. Readers have guessed: the cooling capacity of the air conditioner is designed to recoup the excess heat generated by the technology.

How much power is required from the air conditioner

In light of the above, before installing the air conditioner, try to assess the needs of the cold production. The programs for calculating the power of the boiler can help. The results can be used to calculate heating, air conditioning. Heat loss goes in the direction of lowering the temperature through the walls. Moreover, the value is proportional to the difference, the resistance of building structures. Procedure:

Please note that the calculation is carried out if they failed by searching for the program for calculating air conditioners. The desired figure is immediately given in BTU / 1000 (gradated in the range 07-20 and above). The marking contains the necessary parameter, which is so interesting to buyers and installers. Convert BTU / 1000 to kW. You need to multiply BTU by 0.2931, you get the desired figure. Heating boilers are calculated in kW. We also mention BTU - British Thermal Unit, in English sounds British Thermal Unit.

Now readers know, "seven" is equivalent to 2.0 kW, "nine" - 2.5 kW. We emphasize that the figure has an indirect connection with energy consumption. Every good air conditioner will produce more cold than it will consume electricity from the mains. This is the basis of the idea of heat pumps, however, regular readers of the portal should know and advise the authors. Clarified the calculation procedure. We hope the readers will help each other with links to online resources ... Visit the section on boilers, heaters, which gives the necessary addresses along with explanations of the process of using calculators.

I have never seen programs that take into account the presence of people. If the room is filled with a group, for each person we will add 100 watts of air conditioner power, how many BTUs will be, count! For gyms, we will increase the figure to 300 W, people are engaged in physical labor, which means that the air conditioner will have to sweat more. 80% of the energy expended by an athlete is generated by heat.

Varieties of air conditioner installation

We want to say right away: the installation of an air conditioner can be standard, non-standard. The contents of the prices are attributed to the first case. As for additional options, you will have to find out, along the way overcoming the resistance of the firm's TP. Suppose we want to put a "dvenashka", the freon circuit needs to be increased by several meters relative to the prescribed ones. Get ready to pay extra. The companies' tariffs are different, find out the specific prices.

Why it happens. A typical air conditioner may contain Freon in an outdoor unit. The valves are tightly closed. Craftsmen choose a place to install the air conditioner, start drilling, hammering, pulling, twisting. The inlet and outlet tracts are tied, the drainage pipe is thrown. Before installing the outdoor unit of the air conditioner, the craftsmen discovered that the length was exceeded.

Freon pressure is below normal, you will have to refuel - some troubles. After assembly, the technician will evacuate the air with a vacuum pump, then simply open the valve, allowing the refrigerant to fill the system. A certain system pressure must be maintained. It loses its importance in air conditioners, there are no negative temperatures on the evaporator, it is not critical, get a little steam inside.

The sufficiency of the amount of freon is measured with a thermometer. The master opens the tap, looks at the meter readings. Refueling. With non-standard installation, freon may sometimes be needed. Volume is consumed along the length of the pipes. The air conditioner has a limitation on the length of the freon line, the issue is discussed before buying. The situation in the country is interesting. It seems to be written - air conditioners are installed according to the operating manual, on the other hand, you cannot install any engineering systems at home without a project of an organization that has a license (it seems possible to execute a project, for more details, see government decrees listing the types of activities that require a license).

Therefore, in any case, you need to go somewhere. The designer will want to install it. By the way, you can clarify whether there is a practice of installing devices on the loggia. At first glance, it seems silly, in winter, when heating is required, the operating conditions of the compressor will become softer. Thus, we have no doubt: most readers can install the air conditioner correctly. However, the law needs a draft, even if the drawing is redrawn from the product manual. Traditionally, they forget the water that sprinkles the heads of passers-by. Craftsmen who cut the money are too lazy to look at foreign methods of solving problems. The right path will be found by pedestrians bypassing the pouring streams of semi-rubbish.

Install the indoor unit of the air conditioner before starting other operations. The box is fastened with dowel-nails and other fasteners. In standard models, the power supply reaches the external unit, bypassing the internal one. In the west, there are often structures where the power cables run separately, the compressor is turned on by a relay controlled by a signal with an amplitude of 25 volts. Installing an air conditioner in an apartment is definitely worth it, devoid of the habit of heat. We remind you that the equipment does not in any way replace ventilation, therefore it is necessary to take a power reserve for air circulation. Before installing the air conditioner, take the trouble to do the calculation. Save money.

Installation of air conditioners by foreign companies

Installation of an air conditioner by a foreign master

The first difference: business class houses are equipped with air conditioners. Lost slum videos. There are excellent conditions for installing an external air conditioner unit. According to thematic forums, in America, construction and installation work is done under licenses. There is one professional on the installation of air conditioners on the brigade. He is not obliged to work, he will come, look, leave, without a license, permission, work is not worth a penny. An interesting example of construction.

The external unit of the air conditioner is installed in two ways:

Trampling racks a foot above the ground.
Not high on the wall, two tough guys who bought a ladder or a pickup truck can easily get the outdoor unit of the air conditioner.

The Russian problem of resolving state organizations disappears. The problem of cities disappears. We assume the roofs are equipped with HVAC. The difference between split systems is small. We direct those interested to read the early reviews of the VashTechnik portal. The first eye-catching is communications. American is used everywhere, the USA puts it in a more original way:

The short pipes of the indoor unit pierce the wall.
An additional package is mounted outside, right up to the external block.
Further, see RF.

Let us remind you that Koreans cannot stand nuts.

The operator missed the rolling, we assume the tubes are cut in place. The ends are equipped with nuts with a special tool. The communications are enclosed in a protective shell that prevents heat exchange with the medium. The drain hose reaches the drainage system: culturally, does not water the heads of passers-by.

From the side of the indoor unit, it is possible to change the sidewall, from where the condensate will drain. It is difficult to say why it is being done. Apparently, it is more convenient to start drainage after reaching the sewer. To change the sidewall of the drain, remove the outer cover; hose, plug are swapped. Electrical wiring is carried out with a 4-wire cable thicker than 16 gauge.

Note. The USA has adopted a cable sizing system, with a larger number corresponding to the thinnest cores. It has developed historically, mainly in the United States. The cable was rolled with a machine, passing through increasingly small holes. Accordingly, the 16 gauge went through the operation 16 times.

The wire supplies power, transmits control signals. A color-braided cable is taken, which makes the designations clear: the wiring of the indoor unit corresponds to the external one. Ground (GND) digits 1-3 (phases). To carry out the installation, the shield is removed. On the inner block, a small cover is screwed on with screws, on the right side, on the outside there is a steel ledge on the right side of the case. Power is supplied bypassing the indoor unit. We see no differences.

The USA demonstrates two differences against Chaliapin's homeland:

The location of the external block, which is neatly placed, removed, horrible methods are not invented, such as pulling off the box with a car pull by means of a cable to the ground. Sometimes the body is supported at all by four sturdy struts protruding from the soil by about a foot.
The drain hose is led down the drain. By the way, the measure concerns the bypass valves of water heaters.

Air conditioner installation sequence

Begins to the racks, the installation process of the cameraman cut out. We assume typical screw piles, the rest takes too long. Concrete gains strength for 28 days. Although in this situation, such an exact adherence to the standards may not be necessary. By the way, country houses are placed on top of the pile-screw foundation. It is important during installation to avoid damage to the corrosion-resistant metal layer. Otherwise, rust will eat up the pile reinforcement, and the outer block will fall. When assembling houses, they observe the subtleties of calculating the soil, wind load, we believe that the arguments are unimportant to the mass of 25 kg, represented by the air conditioner box. If only moles, rats stopped digging the soil.

The indoor unit is hung on a mounting plate, which must first be removed from the back wall. In the USA, houses are made of sandwich panels, screws are screwed into the walls without effort. A through hole is made under the communications with a thin drill in a place where there is no wiring. Then with a Forstner drill, the diameter is brought to the desired one. So that both copper pipes, cable and drain hose go through.

The launch process is painfully familiar to our regular readers. The technological map is indicated in the instructions:

We add that split systems with several indoor units are widespread in America. A bunch of parallel pipes sticks out of the right side of the outdoor unit, a pair for each point in the evaporator room. The startup process is not much different. Is it evacuation, nitriding will last longer. We see: air conditioners harmoniously simplify the life of Americans who have settled in cottages, disfigure the streets of Russian cities, where citizens put 2-3 ingots. Figuratively speaking, the technique was introduced by Asia. In England we will also find something similar, in New York on the central streets there will be no swarm formed by myriads of ugly boxes.

The United States uses a variety of air conditioners called HVACs. The fundamental difference is that the fan takes air from all sides of the cubic external unit, blowing it out through the mesh cover. As a result, it becomes possible to install an air conditioner on the roof. The approach deprives the streets of large cities of the ugly boxes that clung to the walls. At the same time, human needs are met. It is clear that the length of communications is increasing. Most of the overseas homes are planned with a forced ventilation scheme. The roofs are dotted with shafts where the blades operate.

In our reality, every tyrant, too lazy to come up with an option is better than installing an air conditioner for show. They explain it by health, other reasons, they avoid buying a monoblock, which allows you to plug the window with a hose. Some of the owners think to decorate the balcony space with air conditioning. Good yield if you follow the instructions.

By the way, before you install the air conditioner yourself, determine the location. Facade installation will require approval. It is not easy with balconies, the owner must fulfill certain conditions. Earlier in 2007, the laws required to independently install the air conditioner according to the instructions. Recently, a bunch of organizations have been recommended to go through. There were rumors in the spring of 2013: the law will be canceled, exactly people are at a loss to sum up the normative background. The system of rules is confusing. Think several times before installing the air conditioner yourself anywhere.

Air conditioner installation guide:
1. Fix the hanging plate of the indoor unit.
you need: a level, a tape measure, a cracker, a small punch / drill, a drill, self-tapping screws, chopiki, a stepladder, a screwdriver, possibly a hammer, a vacuum cleaner, a device for finding hidden wiring.
If something is not there, bullshit is a question, do not rush to buy, because you do not need it except this time. You can hang it on the eye, the garbage is a question that a little crooked, but you can always proudly say, hand mei, he hung it up.
No stepladder, bullshit question, chair to chair steers foreva. It is desirable that the area of the seat of the lower chair be slightly less than the spread of the legs of the upper chair. This will bring special, piquant notes, and neighbors will be able to replenish their vocabulary with catch phrases.
If there is no drill, bullshit is a question, the walls are usually well poked with a nail.
No screwdriver, bullshit question, there is a hammer.
No hammer, bullshit is a question, something hard to find is not a problem.
If there is nothing to fasten with, bullshit is a question, nails, tape, cold welding, glue, for greater reliability, it is better to combine several fastening methods.
So, the plate is securely fixed.
-
2. Make a hole in the wall, and not just a hole, but a normal hole so that the rolling pin would whistle through + a slight downward slope.
you need: a large hammer drill, a long drill, a stepladder, masking tape, an industrial vacuum cleaner, a device for finding hidden wiring.
Stepladder, see problem 1, the neighbors will become polyglots.
A device for searching for hidden wiring, bullshit is a question, an additional charge of vivacity will not be superfluous.
A hammer drill, a drill, a garbage question, the nail of course will not work, or it was necessary to start in winter, but a hefty chisel + hammer drives the Foreva. A couple of days of work and an encounter with fresh air.
Molar tape, cellophane, industrial vacuum cleaner, garbage question. As a child, played war games, well, the same + smoke screen and you are invisible to the enemy.
And of course, all your household members will get great, incomparable pleasure doing such a small cleaning after the "war".
Well, the hole is ready, the garbage is huge and crooked, but it will be convenient to lay routes.
-
3. We look at the hole, at the indoor unit at the estimated distance to the outdoor unit and understand that the drain pipes are short, um, a problem.
needed: flaring, gas burner (for correct installation), pipe cutter, drain pipe, flex (insulation is shorter)
Well, myzh are not suckers what kind of thread, it is clear that the foam was bought in advance for a couple of meters of a copper seamless tube of different diameters, or maybe not copper, or maybe not seamless, or maybe not a single one, garbage is a question, the main thing is, what would be cheap, but there , we will adjust in place.
There is nothing, garbage is a question, the main thing is there are pipes, and the miraculous cold welding will fix everything + glue on top + scotch tape + wrap with wire + another layer of cold welding, for reliability, the stump is clear.
The fact that the shavings got into the tubes when you sawed it with a hacksaw. No hacksaw, gnawed with your teeth? you che, grunt on the knee and that's it, then they split the hole with a knife ... the same option, the main thing is more cold welding.
Drainage, drainage, drainage, um, there is a piece of hose from her grandmother's washing machine, which her grandfather gave her in honor of the anniversary of the Battle of Borodino.
In general, they lengthened the tracks, pushed them with tons of ore into the hole, and you thought, three layers of cold welding, glue, 2 rolls of adhesive tape, a coil of 3kg wire weight, a hose, so it was raced like that, the hose was still forgotten, we stuck it all in, Seems to have passed, there is no bias, HZ, the main thing has climbed through and thanks for that
We hung up the internal block ... it is somehow staggering, the garbage is a question, the welding has not yet frozen, with scotch tape over it, with scotch tape. WAH! What a beauty.
-
4. Outdoor unit.
Necessary. Level, small hammer drill, small drill, attachment vn. block, bolts, keys.
And I must say, we live on the first floor, so there are no problems, they just put him on the ground and his mother. Do not forget to put the grate.
-
5. Connect the routes of the indoor unit with the outdoor unit and evacuate.
you need: monomer, compressor, flaring, keys.
There is nothing, garbage is a question, we take a vacuum cleaner, turn on the line at full power in the pipe, the hi sucks and creates a vacuum, oh, how.
And now quickly, most importantly, quickly, until the vacuum comes out, attach the routes to the external block, the garbage question, is it possible in 10 minutes it will come out ... who? Yes, this vacuum is the same, whether it is not alright ... ... no, exactly, the vacuum, after all, doesn’t know how to walk.
Wiring, um, but what for they, Duc, for electricity, exactly, damn it, they almost forgot. There is also a diagram, something is not clear, but what is incomprehensible, screw it under the bolts, and that's all.
Hallelujah, all hooked up.
They crossed themselves…. He said let's go and waved his hand….
……………….
Buzzing ... ..
It is buzzing, it means it is working, but the cold will go, as I say, it will go.
After some time
Shl. So it was so races, they forgot to start up the refrigerant, they forgot to remove the tracks in the flexes.
They forgot something else, HZ what, but forgot something.
Bullshit question, call the office, let them come to change under a guarantee, a defective one got caught. After all, ********, ***** they will vparyat all sorts of things, and then torment normal people. Although they saved money on installation, it's not so offensive, so their races are so.
A curtain.
A guide for self-installation of a split system, FOR KETTLES, STEP BY STEP, IN FIVE DAYS AND YOU SENSEI is air conditioned.

In the past few decades, household air conditioners have become firmly established in our lives and have become common household appliances, as has happened before with other household appliances - refrigerators, food processors, etc. The air conditioner belongs to complex technical devices, the installation of which is usually entrusted to specialists. However, in some cases, when the services of specialized organizations are not available, and the owner of the home has sufficient skills, the installation of this unit can be done independently.

Varieties of household air conditioners

The whole variety of air conditioning systems can be divided into two main types - monoblocks and split systems.

The main distinguishing feature of monoblocks is the assembly of all units and assemblies in a single housing... These systems include:

Window air conditioners, in which there is a separation of the units inside the housing, while the compressor unit is located on the back side and must go outside the room.

Installing a window air conditioner reduces the area of the window

Cases of floor-standing or mobile air conditioners are equipped with wheels for free movement inside the room. Such systems have an air duct that is led outside, outside the room.

Floor standing air conditioners can be moved indoors

The advantages of monoblocks are directly related to the features of their design:

Cheapness combined with a long service life.
Simplicity of design and operation.
These systems achieve the highest possible efficiency.
Fast air cooling.
Most modern systems are equipped with remote control panels.

Such systems are not devoid of a number of design flaws:

The number of possible installation options is limited (either in a window opening, or in a place from which it is possible to bring out the duct sleeve).
High noise level.
The need to change the geometry of the window and fasten complex suspension units in the case of installing a window air conditioner, which entails additional costs.
In the case of installation in a window opening, the illumination of the room is reduced.

A design feature of split systems is the division of air conditioning units into two units, one of which is a compressor, which is taken out into the street. Unlike monoblocks, split systems have more varieties, but only some of them are used in residential premises:

The most widely used wall devices are when a hairdryer or indoor unit is attached to the wall of the dwelling, and the compressor in the outdoor unit is brought out to the facade. Inverter and non-inverter models are distinguished as one of the types of such systems. In the first, the alternating current is converted into direct current, which makes it possible to regulate the compressor speed.

The split system hair dryer can be installed anywhere on the wall of the house

Floor-ceiling systems are used less often. Their highlight is the ability to install a hair dryer either under the ceiling or on the floor. Accordingly, air flows in the first case will spread from top to bottom, and in the second - from the floor up.

Indoor block of floor and ceiling split system

Another type is multisplit systems. Their design provides for the presence of one outdoor unit with a compressor and several indoor units, which are installed in different rooms of a house or apartment.

The multisplit system is optimal when it is necessary to air-condition several rooms

The indisputable advantages of split systems include:

Low noise level.
The function of cleaning the air from bacteria and dust.
The presence of a heating function in the cold season.

This is interesting: quite often the heating function is provided by manufacturers in modern monoblock systems, both window and mobile.

The compact size of the indoor unit, which can be mounted in any room size.
In many modern systems, there is a function of dehumidification and humidification of air, which allows you to create a comfortable microclimate in the room.

Disadvantages of split systems:

Their cost is higher compared to monoblock models.
The need to carry out a large amount of specialized work, including facade, both during installation and when the need for repair and preventive maintenance arises.

Methods for installing air conditioners in an apartment

Monoblock models of window air conditioners are now being purchased less and less. The reason for this is a significant increase in the percentage of installation in dwellings of plastic and other windows with standard double-glazed windows. It becomes difficult to change the geometry of the window opening, because such air conditioners are installed directly into the window unit so that the rear part with the compressor is outside the room. Such a system can be installed both in the lower part of the window, in this case, it rests on the window sill, and in the upper one, using brackets to the ceiling or wall.
Mobile attachment systems are not required. The place of their installation is selected based on the possibility of removing the soft corrugated duct pipe outside the room. The technical solution to this problem is left to the discretion of the buyer.
Installation options for split systems are more diverse. This is due to the numerous options for the interposition of the indoor and outdoor units and depends both on the wishes of the owner regarding the place of attachment of the indoor unit, and on the technical ability to fix both the outdoor and indoor units in a specific place. Of no small importance is the possibility of laying communications between the blocks. The optimal solution is usually based on a scheme in which the distance between the external and internal units is minimal. This solution allows you to minimize the amount of work associated with laying communications and allows you to save energy by reducing the heating that occurs during the circulation of the refrigerant.

Photo: the most commonly used layouts of the external and internal blocks of the split system

Cooking tools

If the decision to install the split system on your own is finally made, first of all, you should check the availability of the necessary tools and consumables. For the complete work you will need:

Perforator with a drill with a section of 40–45 mm and a length of at least 800 mm.
A set of victorious drills with a diameter of 6–12 mm.
Screwdriver with a set of bits.
Metal scissors and reamer.
Ruler, pencil and building level.
Adjustable wrench.
Vinyl insulation, masking tape and plastic bags.
Brackets for fixing the outdoor unit, bolts with dowels 120 mm long.

When deciding on self-installation, it is worth considering the degree of accessibility to the installation site of the outdoor unit. If it will be mounted at a considerable height, you will have to include in the cost of renting an aerial platform.

How to install a split system with your own hands

At the first stage, a split-system hair dryer is installed, that is, an indoor unit. The perforated steel panel on which it is mounted is removed from the back wall and attached to the wall where it will be installed. It is very important to make accurate leveling, after which the holes for the fasteners are marked. The presence of slopes is not allowed, as this will entail the overflow of condensate from the body onto the floor of the room. Another important point is that the distance to the ceiling should be kept at least 7 cm. Holes are drilled in the wall with a puncher, after which the plate is fastened with self-tapping screws and plastic dowels. Usually, dowels with a cross section of 8 mm and a length of at least 32 mm are used. After attaching the hair dryer unit to the latches, the horizontal accuracy of the fastening is checked again using a level.

The next step is to prepare the communication channels. If a concealed gasket is to be used, you will have to make grooves using a hammer drill. However, such a solution entails the production of cosmetic repairs in the room. Therefore, at present, most often communications are hidden using a plastic box of a suitable section. With the help of a perforator and a drill, a hole is made in the outer wall for leading to the outdoor unit of the power supply and control cables, PVC tubes for draining condensate and tubes of the freon circuit. Marking is done using a ruler and a level. An important point: in order to ensure the drainage of condensate, ensure a slight slope of the outlet towards the street. When drilling, it is worth using a vacuum cleaner and fixing a plastic bag directly under the hole with masking tape in order to avoid significant contamination on furniture and walls. If the length of the drill is not enough, drilling is done from both sides. In modern houses, the wall thickness rarely exceeds 1 m.

The hole is drilled with a slope towards the street

After that, the most difficult stage begins - the installation of the street block. Since the compressor is located in this unit, it weighs more than 20 kg, while the installation is often carried out at a considerable height. Therefore, do not forget about safety measures, in particular, use safety equipment. Most often, the outdoor unit is mounted on a wall using L-shaped brackets. First, the location of the brackets is marked on the wall and holes are drilled. Then it is fastened with bolts and nuts using washers. The external block of the split system is bolted onto the brackets, while gaskets made of thick rubber are mounted under the legs to reduce vibration and noise.

As a possible option, the installation of the outdoor unit on the roof of the building or directly on the ground is used. In this case, U-shaped brackets or frame metal supports are used. Such a solution can significantly increase the length of communications and is used when it is impossible to mount the unit on the wall, for example, when the strength of the wall surface materials is insufficient.

The next stage is the most crucial. In the course of it, communication is made between the external and internal blocks. First, the plastic protective cover on the outdoor unit is removed and, in accordance with the manufacturer's diagram, the power and control cables from the indoor unit are connected to the terminals using bolts. Then the length of the freon line is measured and the copper pipes are cut with a margin of 10 cm. The ends of the pipes are rolled and a chamfer is removed with a reamer. The copper pipeline is connected first to the external block, then to the hair dryer with an adjustable wrench using union nuts screwed onto the fittings in both blocks. Before the copper pipes are passed through the hole in the wall, vinyl thermal insulation is put on them, the ends are insulated with tape so that debris does not get inside. A drainage drain tube is also being installed; it is made of a corrugated PVC plastic pipe, which is attached to the block with plastic clamps.

The last stage is the introduction of freon into the refrigeration circuit. First, the gas is removed from the circuit by opening the valve, followed by evacuation. The refrigerant is in the outdoor unit of the air conditioner. The valves, with the help of which the freon is introduced into the system, are located in the same place. If the length of the contour is equal to or less than the data specified in the data sheet, the introduction of an additional volume is not required. Experienced craftsmen, before this operation, evacuate the circuit using a special pump with pressure gauges to control the pressure loss. These actions allow not only to check the tightness of the system, but also contribute to the maximum removal of moisture and air from the system, which reduces the load on the compressor.

Before introducing freon into the system, professionals perform a vacuum circuit

At the end of the work, the assembled split-system is checked in all operating modes. There must be no vibration, the fans on the indoor and outdoor units must rotate. There should be no foreign odors, the drainage should remove moisture. Of course, the air conditioner must fulfill its functions of both cooling and heating.
