Options for upgrading and editing ventilation systems in the bathroom. Forced ventilation in the bathroom and toilet vent hole in the bathroom

At the time of layout of the interior and finishing works in the bathroom, you need to pay attention to a very serious question, this device of normally functioning ventilation. Well-arranged ventilation in the bathroom and the toilet performs not only the role of the main air exchange, but also guarantees admission to the room of fresh air.

With the help of a well-equipped ventilation system, the opposite stench is eliminated from the bathroom and the toilet and excessive humidity. Therefore, at the expense of a competently thought-out and clearly mounted system of correct ventilation, the owners, in the apartment of which such an air extractor is installed, should not worry about the appearance of various molds and smells of dampness.

Ventilation system.

In construction standards, prescribed in reference books, the necessary norms that need to be performed to achieve a good result are performed, when carrying out the premises of the bathrooms with a large concentration of wet air.

According to the standards, ventilation provides a fresh condensation in the amount of 25 cubic meters per hour for the premises of the bath and toilet, and for room with combined bathrooms, the norm will be 50 cubic meters per hour. These are average standards for ventilation systems. Sometimes such rules may recommend to increase to 150 cubic meters per hour.

Depending on the air ventilation method, ventilation can be divided into natural and forced system . In the first embodiment, the ventilation of the room is performed due to the difference, which is due to different air pressure outside and indoors.

Air flows pass through doors and windows, as well as special ventilation holes in the toilet and bathroom. True, it should be noted that due to the special internal arrangement of the premises of the bathrooms, the use of a natural way to ventilate the room does not always make it possible to obtain the desired result. To improve the natural way to ventilate the room, you need to make the opening, connecting the hole for natural ventilation in the house, with a bathroom.

During the implementation of a forced or artificial method of ventilation of sanitary nodes, use specialized fans giving an intense stream of fresh air, providing a good air exchange.

Often the electric fan sends air flows from the sanitary node to the street, while fresh air penetrates the bathroom from the rest of the apartment.

Very often owners install in the toilet with their own hands small electric fan - Inventory, even considering the fact that there is excellent natural ventilation in the house, it is done to accelerate the cleaning of airspace in a room from disgusting smells.

If the owners fail to obtain good, natural ventilation in the bathroom and the toilet, the forced ventilation in the premises must be installed.

Types of ventilation.

Ventilation is divided depending on its application on:

Exhaust type of ventilation, installed indoors.
Ventilation type of ventilation.
Mixed ventilation indoors.

Exhaust ventilating room , We have previously described - this is when fresh air enters the room through external sources, squeezing the old air mass due to the pressure drop in pressure.

Ventation of ventilation In the bathroom and toilet rooms are performed in another way, the air mass is heated from the outside, it is squeezed through special intensity.

During operation mixed system Air ventilation uses an adjustable air mass flow in rooms of various purposes.

The ventilation system may also have or not have a channel for air flow ventilation, so it is divided into channel and infantal.

If it is possible, you must avoid the channel ventilation device. The best way out in this case, expand a little hole in the wall, which serves the access to the general ventilation channel of the multi-storey house, and mount a small fan for an air exhaust.

In a separate toilet and bathrooms, if you have only one hole for airing with access to the overall ventilation in the house, one more hole with a fan is made between the bathroom and the toilet.

Installation of a special channel for ventilation makes sense in those places where it is necessary to increase the room from contaminated or wet airspace.

Diagnostics of the ventilation system.

Before improving ventilation in the bathroom and toilet, you need to very carefully familiarize yourself with its device, and diagnose its condition.

How to check the ventilation in the easiest way to learn everything in order with her. For this, first of all studies air pullTo the vent hole, you need to bring a burning match or lady. The fluctuations or displacement of the flame in the direction of the ventilation channel are proof that everything is in order with the air burden. In hot or windless weather, the air thrust is significantly reduced, compared with windy or cool weather. Such a diagnosis is preferably carried out at the open, and with a closed door to the bathroom room, in addition, for a more improved effect, you need to open the window in the apartment overlooking the street. In the event of a decrease in the receipt of fresh air, it is best to establish funds that will complement the ventilation system. Usually in this case, special gratings are mounted in the door in the bathroom and toilet in the doorway in the bathroom and toilet, due to which the normal supply of fresh air mass is carried out with tightly closed doors.

Even if there is good air thrust in the system, it is not always possible to make a conclusion about the normal functioning of ventilation. How to make ventilation in the toilet and the bathroom normally working, the output is quite simple. To do this, you need to check the operating condition of the channel for an air exchange, which may have ceased to function normally as a result of non-professional repair work or due to some unidentified reasons. Completely eliminating various blockages and clogging in the channel, it is possible to change the operation of the air ventilation system for the better.

Features of fans.

By acquiring Fan for Extenuina , It is mandatory to give an assessment of noise that comes when the device is operational. With normal operation, noise amount should not be higher than 35 decibels. At the same time, in the room as a result of air circulation, fresh air should update the room from 5 to 8 times in one hour. To calculate the device's performance, the room is needed, calculated in cubic meters to multiply by 5, and the result obtained increases by 20%. The fans differ in the installation method, the device of one species are installed in the channel for ventilation, there are radial devices mounted at the output from the channel. Such fans have a kind of look, as hidden from the inside. Radial type models typically have a decent appearance to fit into the overall interior of the room.

Models of fans may also have a strong difference:

Conventional axial devices Support an air mass along the axis of the structure using the use of blades used for champless devices.
IN diametrical devices Low performance applies a drum wheel wheel.
Centrifugal models have an increased efficiency factor in work, as well as a large level of noise.
Centrifugal axial fans Make less noise, but give the same effect when operating as centrifugal instrument models.

Improving ventilation in the toilet and bathroom, on the fans in some cases, the timers and gyrostats are mounted, with which it is possible to extend the operation of the device to achieve a greater result.

Devices whose power is extremely weak, cannot perform effectively weathering of odors and moisture, but also to operate high-power models is not desirable. Devices having high power can give such a highly intente air flow that air will not come from outside, but from various holes for ventilation, in this case, the edge air will again come to the room.

Ventilation system.

If there is no ventilation system in the room for some reason, it is necessary to immediately make ventilation in the bathroom, it is not too complex process.

High-altitude houses are designed so that the ventilation shaft is placed behind the wall of the bathroom or toilet room. Mount properly forced ventilation in the bathroom and the toilet is not very difficult. It is necessary to make a neat outlet if it was not, then attach from the inside the hole of the radial axial type fan, and connect it to electricity in compliance with all the rules and requirements for the operation of electrical devices in high humidity conditions.

Extension for aesthetics is covered with a beautifully made lattice. If the living area has a separated sanitary assembly, and the vent hole is located on the wall between two rooms, the installation of the second fan occurs in the method described above. In some cases, it is very convenient to use decorative lattices specially designed for the device in them fans.

It is much more difficult to establish ventilation in the bathroom and the toilet when the ventilation shaft is bordered by another room, in this case there is an installation of a channel exhaust. To start work on the device you need to choose a place for the inventory of the bathroom and in the toilet. After that, you need to consider the device plan for ventilation, the air masses will go to the mine.

Ventilation boxes Have a difference in the following characteristics:

The box is rectangular or round shape made of plastic.
Hard and soft type boxes made from corrugated iron.
Box of rectangular shapes made from ordinary or galvanized tin.

Plastic products lightweight and very simple when applying forced ventilation in the bathroom. They are much longer than metal products, have the price below and easier to care. For this reason, today in the market of building materials, products from plastic actively displaces metal products. As for the use of corrugated products, its use is extremely rare, and this does not have any influence on the overall picture.

The box is best set even before the start of the main repair work, but the installation of electrical equipment and lattices on the outstand are carried out after the main finish. At the final stage, the mounted equipment is inspected.

Errors that are possible when ventilating device.

Sometimes it happens that the newly installed forced ventilation in the bathroom, gives malfunction and does not meet its requirements. This is a consequence of improper installation of the device and some errors performed at the time of installation. Even before the start of installation, it is necessary to clearly know how to make ventilation in the bathroom and toilet.

Here are some mistakes, often allowed in work:

The ventilation channel is incorrect, it creates difficulties for the movement of the air flow.
Range of sealed ventilation channel connections.
Incorrectly installed fans, while they make a big noise.
The ventilation channel stretches through the rooms, creating unnecessary noises with its work.

Most of these unpleasant problems may not allow. How to make ventilation properly, for this it is necessary to pay attention to the stage of compiling and thinking on the plan of the future installation of the structure. If this is not fulfilled, and unpleasant problems have already arisen during the work of the ventilation system, in this case it may be necessary to complete the alteration of the entire design.

Another way to make forced ventilation normally functioning is to apply various noise absorbers and installation of a more powerful fan .

The health and well-being of residents of the private house largely depends on the qualitative characteristics of the air, which they breathe. In apartment buildings, the ventilation of residential premises designs and assembles the developer. In her house it is necessary to worry about the owner on their own. The ventilation system mounted in the private home bathroom is natural and forced. Which one to choose, think you.

Natural ventilation is suitable for houses built from "breathable" materials. Forced ventilation is required for houses erected using modern hermetic materials. The forced hood is selected for the bathroom in a private house, taking into account the square of the room of the bathroom and the number of tenants.

For the efficient operation of a natural ventilation system in a country house, it is necessary to organize the influx of fresh street air and an outflow of air masses through ventilation mines. In the house with wooden windows, fresh air can be leaked through microscopic slits in the frames.

The optimal height of the ventilation supply valve in the outer wall of the house is considered the distance from 2 to 2.1 meters plastic windows with multi-chamber windows is preferably embedded for regular outdoor air flow climatic valves. Replace these windows on the windows can supply valves installed in the bearing walls under the windowsill over the batteries or side of the window openings.

At the same time, cold air flows coming from the street will be mixed with warm air, heated batteries. This means that the house does not appear unpleasant and dangerous drafts.

How does the air fit in the bathroom?

The new air portion of the new air comes from other residential premises of the house through a 2-2.5-centimeter gap between the floor and the door blade, provided when mounting the door in the bathroom. Another option of air intake in the bathroom is the purchase and installation of special doors, in the canvas in the lower part, the presence of ventilation holes in the form of lattices or round windows is provided. Sometimes for these purposes, the door in the bathroom is not tightly covered, especially when it does not use it.

Interior bathroom doors equipped with four round holes, closed decorative lattice elements

Where is the couples and smells from the bathroom?

Expanded channels serve ventilation mines, directed vertically upwards. The bathroom should have its own separate ventilation channel, the side output to which is designed in the upper part of the wall in the sanitary and hygienic room.

A direct exit to Ventkanal cuts through directly in the ceiling of the bathroom. It is in these channels that pairs are delayed, as well as all foreign smells. The ventilation window is closed with a decorative grid. In no case can not stick the windows for ventilation by wallpaper or other finishing materials.

With the right installation of natural ventilation in the bathroom there will be dry air. Thanks to the timely assignment of wet air, you will not come across the problems of the appearance of mold and rotting materials from which your home is built.

The ventilating window in the bathroom wall has a round shape and closes with a light decorative grid in the white ceiling tone

Ventilation device for two rooms

In a two-story house-cottage through a ventilation mine, which is located from the bathroom located on the first floor of the object, you can organize an air extractor from the room of the second floor.

At the same time, they are cut into Ventkanal not immediately at right angles, but through a small knee, the part of which is parallel to the exhaust riser.

It turns out that the air is dragged through the hole below the entrance to the ventilation shaft. It is done in order to prevent suction of elongated wet air from the bathroom in a living room on the second floor.

Installation of ventilation canal

To collect and install the ventilation channel in a private house, a diverse-spent air straight to the street, you can from ready-made warmed elements. Such ventilation systems are manufactured by well-known manufacturers and are collected as a constructor. The cost of them is high.

Choosing suitable materials

Solve the problem of the orange-colored sewer pipes, which are used to carry out the outside network of autonomous sewage. The walls of these pipes do not crack in the cold.

Pipe diameter Choose from room area: 100 or 150 mm. The length of the entire pipe is calculated on the basis of the fact that Ventkanal should be placed above the roof half a meter. The higher the pipe, the stronger the thrust.

Drinking the ventilation holes

To the upper end of the pipe put the plug so that the precipitate does not fall inside the ventilation pipe channel. To remove the air at the top of the plastic pipe, they are made in a circle of oblong slits, the width of which is 20 mm, and the distance between adjacent holes is 30 mm. The length of the fixed rectangular windows should reach 250 mm.

Insulation of the walls of the ventilation pipe

In order for inserting Ventkanal to be condensate because of the temperature difference in the attic and on the street, it is necessary to inspire its walls well. Suitable basalt wool or isolon.

The entire pipe is wrapped with a foil insulation shiny side to the walls.
Seam connecting with foil scotch.
Then once again we rocked the insulation so that the seam comes from the other side of the pipe.
And again we sink scotch.
After that, the homemade ventilation pipe-shaft is wounded in a circle all completely scotch.

Ventilation hole device

In the bathroom ceiling in a private house, a hole is made equal to the diameter of the insulated tube. The pipe-hood with the top end is inserted into the opening done in the roof, and starts the lower end in the ventilation window carved in the ceiling overlap.

The homemade vent car can be fixed in a strictly vertical position of the clamps to the rafters of the roof or to other structures available on the attic of the house. In the bathroom, the hole in the ceiling is decorated with a grid, selected in size and color. Self-tapping screws or liquid nails are used.

Installation of supply valve valve

The natural ventilation system in a private house works with the greatest efficiency only if it is thought out of a way to provide a permanent tributary from the street of fresh air. This task is perfectly solved by setting the valve in the wall of the private house. Street air falls into the house even with tightly closed plastic windows, passes through all the rooms and is displayed through the exhaust hole in the bathroom, closed with a decorative grid.

Thus, a permanent air exchange is carried out, which is necessary to eliminate unpleasant smells from the bathroom, saturation of the closed space oxygen, the leads for heavy humidifier outside the house on the street.

The device for the design of the supply valve allows you to understand how fresh air is served from the street into the house and in what volume

To mount the supply valve of the supply ventilation in a log house, you will need:

ordinary drill;
crown with a diameter of 133 mm with a centering drill;
chisel;
a hammer;
panel or mounting foam;
hoven for metal;
screwdriver;
self-tapping screw;
screwdriver.

In the residential room of a private house-cottage in the upper part of the log wall with a drill and nozzle-crowns with a centering drill, a hole is drilled, a diameter of 133 mm. Works lead in several techniques, spinning drilled part of the tree with the help of the chisels and hammer. The hole in the outer wall is given a small bias towards the street with the aim of leading condensate.

The supplied ventilation valve includes a meter metal plastic pipe, the inner walls of which are insulated with basalt thermal insulating material. The insulation does not allow the wall to precipitate in the zone of the drilled hole. A piece is cut from this pipe, the length of which corresponds to the thickness of the log.

The pipe is started into the hole in the wall. Small gaps are insulated with packs, which clog the gaps on the thickness of the wall. You can swap to replace with mounting foam. Next, from the street side, a lattice is put on the pipe equipped with a grid from insects. Decorative lattice comes with a valve.

Installation of the supply valve in a wooden house can be made on their own without the involvement of ventilation specialists

Lastly, the valve itself is installed. To make its installation, you need to remove the adopter and free access to the fasteners. The valve consists of two petals opening under several angles of inclination. On the case there is an arrow, the direction of which is taken into account when installing the valve into the plastic tube.

Additionally, the valve to the wall is secure self-made. After that, we put the headband, snapping it on the fixed part. We return a wheel that regulates the degree of opening of the valve petals.

Forced ventilation of the bathroom room

If the thrust in the ventilation shaft is weak, then increase the outflow of heavy wet air from the bathroom with an electric exhaust fan. Check the force of thrust using a sheet of thin paper or a lit match. If the leaf sticks to the exhaust window, and the flame stretches towards the drawing, then the thrust is good.

With a slight pull or when it is lacking, the single output will be the installation of the exhaust fan. At the moment you can choose exhaust fans for a variety of situations, various sizes and colors. It is advisable to calculate and install the fan of the desired power, then your time spent in the bathroom will be comfortable.

Models of fans with check valve in exhaust ventilation are very popular. As a rule, the check valve is already initially provided in the fan design. The valve curtains are automatically opened with even a small air current from the room and slam in the occurrence of air reverse current - to the room.

Transparent reverse valve curtains operate on the Nipple system. The air current ventilation system is free, back completely blocked

This design is very important when a situation is very important when due to errors when calculating and installing is possible a reverse current of air from exhaust ventilation into the room. And the shutters are autonomous and operate when the fan is turned off.

Choosing a household fan with check valve

Before buying a fan, you must unscrew the decorative panel and measure the dimensions of the opening, if it was provided during the construction of a private house. The data received is sent to the store to choose and buy the appropriate valve appropriate to the dimensions. When choosing into account, it takes a smaller measurement so that the round case enters the window.

Among the models suitable in size, the fan is already selected for a number of other criteria:

design;
electric motor power;
electric consumption class;
the presence of the check valve;
silent;
the mobility of the curtains and others.

A variety of exhaust fan models for the bathroom allow the buyer to choose the device, ideally the corresponding interior of the bathroom

Extension Fan Connection Options

There are several ways to connect an exhaust to the power grid. The device can be activated on sensors (motion or humidity), as well as simultaneously with light. Termination of the fan can also be set in several ways - by timer at a specified time or switch, which must be installed inside the bathroom. Reverse valve automatic and its work does not depend on electricity.

Connecting an exhaust to a light loop provides the beginning of its operation at the moment of light on. At the same time, the fan must have a separate switch, with which it will be possible to disconnect the lighting and ventilation of the bathroom in case of need. The switch can be mounted on the wall or is located on the fan housing.

One of the possible fan connection schemes in the bathroom with a separate switch for the device.

In the latter case, the disconnection of the device is performed by jerking over the rope or chain. Choose a long-lace model so that the hood can calmly turn off family members who do not have high growth. In principle, from a short lace can always be done long by extension.

Trial shutdown has its pros and cons. You can not worry about what you will forget to turn off the electrical appliance. If you need to reduce the opening time or, on the contrary, increase, compared to a given value, then inconvenience appear. Therefore, choose a model with a switch so that the fan worked when you need.

Installation of the fan in the bathroom with your own hands

Before installation, you should carefully read the instructions for installing the axial fan. Get out of the box the device and all components going with it. This is usually fasteners in the form of four dowel-nails. In order not to drill a tile, you can replace a dowel fastening on the adhesive connection. However, remove the glued fan for cleaning and repair will be very difficult.

The magnitude of the minimum distance on which the fastening of the exhaust fan is made to the wall by means of screws twisting by the usual screwdriver

Therefore, we consider in more detail how to make a forced hood from the bath in the house with a miniature wall fan fixed by self-draws.

remove the decorative grille from the device, unscrewing the screw or simply declining it (in various models in different ways);
insert the cylindrical part of the fan body into the exhaust hole;
marker We note the place of drilling the tile under a dowel or self-tapping screw, depending on the material of the wall;
we remove the device towards the device and proceed to drill the tile;
drill the tile can be drill using a special feathery drill, or a perforator, which is a bit more complicated;
plastic dowels are filled into the obtained holes;
in a special opening provided by the manufacturer, drive the wires to connect the motor to the power grid;
if the location of this opening does not suit you, then we drill a new hole in the hull panel;
set a household fan, combining eye dryers in a housing with drilled holes;
screwed screws diagonally so as not to twist the plastic body of the device;
remove the fan impeller, freeing access to contacts inside the instrument;
in a clobal block, we start the stripped ends of the wires and clamp them with the bolts;
klema block put in place, laying the wires in a special groove;
check the performance of the installed fan by turning on the light with a parallel connection or by pressing the appliance's own switch;
after checking, you snap the decorative grille on the fan body.

Forced hood is mounted and ready to fight with wet and contaminated air in the bathroom.

Connecting the wires is carried out using various clermets. It is not allowed to use wires to twist the wires, isolating them with a tape

Note! Wires must be added in advance under the tile during the cladding of the walls in case of installation of forced ventilation. If this was not done, then the wiring lead along the tile in plastic boxes, which are glued to the cafél with polymer glue.

This video shows the installation of a ceiling exhaust fan in the bathroom, which is located on the project on the lower floor of a private two-storey house.

Ways to combine two types of ventilation

With the hood enabled, the volume of the incoming and discharge air increases. During the device to turn off the device, the ventilation process of the residential premises is practically absent. This is due to the fact that the fan housing completely overlaps the clearance of the ventilation window. Propeller blades interfere with the natural outflow of air from the bathroom. The problem is solved in two ways.

Insert a dual grid in a large ventilating window, in which there is a round window under the fan and several additional slotes for the natural outflow of air.

There are fans with different diameters of the housing, so you can choose a smaller device than the vent hole. When the fan is turned off, the air will go through a simple grid under the device.

If the ventilation window is small, then the fan is on the legs of 1.5-2 cm. The legs do not give the lattice to the wall tightly to the wall. In the articulated space, the air is delayed under the action of the force of the thrust formed in the mine, and goes through the holes, not closed with a round body of the fan.

The legs make their own hands from ordinary foam. Self-tapping screws are well through this material. Fontoam legs also serve as a shock absorber that reduces the degree of vibration of the working exhaust.

An example of integrating two types of ventilation - forced and natural - in the private house in the bathroom

Having learned in detail how to make a bathroom hood in a private house, you can decide yourself - under the power you have this task or not. Perhaps the best solution will appeal to the company providing services in your region on the installation of all known types of ventilation.

To create a favorable microclimate in a shower room, a high-quality air purification system is needed. Forced ventilation in the bathroom qualitatively performs duties assigned to it. It allows you to normalize the functioning of the room, to save it from dampness, high humidity, which is due not only to comfort, but also sanitary and hygienic standards. It is through the exhaust hole that the space is filled with freshness, which relieves it from various microorganisms.

Checking performance

In order to establish the health of the natural air, it is necessary to adhere to the following evaluation criteria:

After bathing procedures, mirrors remained in the room, as well as ceramic tiles and other interior items, which indicates a malfunction of ventilation.
The paper brought to the exhaust hole in the toilet is not pressed against the barrier lattice, then this is the second sign of troubleshooting.

Improve ventilation in the room can be given in these ways:

cleaning mines;
installation of an additional fan;
installation of a forced air exchange system.

Varieties

It is no secret that there are special parameters that regulate the state of hygienic standards. It is for this that is established. The estimated functioning of the system should be 25 m 3 / h of fresh air into the apartment, if the bathroom is combined, the indicator increases to 50 m 3 / h. These standards directly relate to natural and artificial ventilation without exception.

The natural air movement allows you to provide a freshness bathroom and toilet room, guided by the laws of physics. This means that nature due to the difference in pressure and temperature itself directs air masses to the house. Separately, it is worth noting the fact that it causes significant difficulties during ventilation - the obstacle to the closed plastic windows with the normal functioning of the exhaust hole.

Thus, for better ventilating room, they need to open more often. Artificial system using the installation of additional devices will make this task easily performed. Types of fans are divided into the following:

In addition to this gradation of the ventilation construction, there is another one. It happens:

Babeless, i.e. Air exchange occurs on generalized mines of multi-storey or private houses.
Channel. This system is characterized by special supply to sites where the intensity is necessary in the process of purification of atmospheric masses from steam, moisture, unpleasant odors and other harmful components.

In this regard, the ventilation in the bathroom and the toilet room is installed along with the forced systems, the fan is installed with the reserved switch, which makes it use very convenient. This method allows to apply the system even on time to take water procedures or toilet visits.

We choose the model

In order for the exhaust hole worked smoothly at the maximum of its capabilities, it is very scrupulously approach the main functional product - fan. Therefore, it is necessary to learn the individual moments better, which will facilitate the determination procedure with the type of ventilation design.

Noise level

It is quite natural that when working, household appliances produce a certain level of sound. For ventilation equipment, this indicator is always indicated in his passport. Bathrooms and toilet rooms allow you to install the system of approximately 35 decibels, which is considered a high level of noise insoles, since this sound is not perceived by human hearing. The fans with higher sound indicators are already considered unsuitable for use due to their irritability.

Engine

The instrument for toilet room should have the necessary power, as well as a long safety margin. It is these indicators that corresponds to the fan engine. When inspection, you should immediately pay attention to its device. Ball bearings and installed bushings must be present, on which the duration of the engine operation depends, as well as the level of noise produced. Such models are rightfully considered the most productive, durable, silent.

Performance

This indicator is considered one of the most important for the functioning of the entire ventilation system. Due to productivity, you can calculate how much fresh air comes to a bath or toilet space in 60 minutes of its operation. It should be understood that the fan performance is directly related to the following parameters:

room area;
humidity level;
number of active users.

The desired performance of the ventilation equipment can be installed with a fairly simple formula. It is necessary for the total volume of the desired room to multiply on the multiple value of the air exchange, the indicator, which, in turn, is the value of the amount of complete change of the atmosphere in the toilet. For the bathroom, approximate multiplicity will be equal to the indicator from 7 to 10 units.

Today, it is obvious that the technology does not stand still, so the modern market has already been providing innovative instances of the ventilation system with the following functions:

automatic connection to the switch;
independent work when achieving a certain level of humidity;
software installation of tasks on various criteria.

Types of models

Ventilation structures can be equipped with various designs that significantly improve operational characteristics. They are divided into:

Installation of equipment

To date, almost each of us will be able to install the ventilation design yourself. For successful completion, it is necessary to take into account the literally several useful tips:

You need to make sure that there is no clogging of the common air mine, if the answer is negative, then it is worth cleaning.
It is best to create a small slot under the door to implement reliable thrust or set the lattice on the doorway.
The success of ventilation directly depends on the competently selected equipment. Therefore, it is necessary to take into account the operational qualities of the fan, its safety and functionality.
Exhaust models should display atmospheric mass through a special hole in the overall aircraft. This technological hole is in each apartment, as it provides natural ventilation.
Before starting the installation, it is necessary to carry out a wire for power supply.
Installation of ventilation is carried out only strictly according to the manufacturer's instructions, where all the subtleties of the process are described.

Video instruction

Prevent the appearance of dampness, mold and fungus will help install ventilation in the bathroom and toilet. This should be provided before the start of major repairs. In these rooms, there are constant temperature differences and the humidity of the air is increased, which will certainly affect the state of the walls and the ceiling, where the pathogenic flora will begin to develop. For work, you can invite the wizard or do it yourself.

Types of ventilation systems

Ventilation in the bathroom of a private house or cottage is pretty simple: the air channel is located under the ceiling and is displayed on the roof or in the overall hood. When opening the door, the air flow enters the room and goes through the pipe, creating a natural circulation.

In apartment buildings, the situation is a bit more complicated: the entire entrance is connected to one ventilation channel. In apartments located on the lower floors, the risk of clogging the air exchange system is much higher.

Forced ventilation in the bathroom.

The main types of ventilation include:

natural;
forced;
combined.

The choice depends on the place of residence and state. In high-rise buildings, preferably forced ventilation.

How does a natural air exchange

Properly installed extractor works very simple: the air falls into the bathroom or toilet, and then goes out through the ventilation shaft. The difference in temperatures in the room and on the street creates a craving, with the help of which air flows are constantly moving.

When air outputs from the hygienic room, a zone of reduced pressure is created, the difference compensates for the inflow from the street, entering through the open window when carrying out. Thus, natural ventilation occurs, which is called the supply.

Natural ventilation can not occur if the door to the bathroom or toilet closes hermetically. For normal circulation of air flows, it is necessary to provide a slit between the door and the floor, through which the fresh air will continue to flow.

If there is a violation of natural or mine) problems instantly arise: humidity increases, unpleasant odors appear, condensate can accumulate on smooth surfaces and heating pipes.

Defining a blockage in a pipe or mine

The working condition of natural ventilation is better to check in the cold season. For this you need:

open the window in the house or apartment for the receipt of cool air;
close by applying a sheet of paper;
if the sheet is not pressed the air flow tightly, then the ventilation is clogged.

The degree of blockage can be determined by paper behavior. If it holds weakly, the air passes, but not in full. If the sheet does not hold at all, the channel is completely clogged. And in that, and in another case, cleaning or installation of a device for forced ventilation is required.

Forced ventilation

Unlike natural, forced ventilation in the toilet and the bathroom provides a fan built into the air exchange system. When it is selected, it is necessary to consider that it will consume electricity and work with high humidity.

Installation of ventilation in the bathroom and toilet, its cost, durability, performance and noise level depend on. It happens three types:

diametral;
axis;
radial.

The first device is not suitable, it is designed to work in air conditioning systems and heat guns. You need to choose between two other types of devices.

The axial model differs from radial lower cost and greater power, but it produces more noise. The operating wheel of the axial fan is driven by the electric motor, the air flow goes along the axis of the motor, it is installed directly onto the hill for the exhaust.

The operation of radial fans is based on centrifugal strength, so electricity consumption and noise can be reduced by changing the slope of the blades. Install such a device in the ventilation pipe, at some distance from the lattice.

How to choose a fan

Buying the desired fan is hampered by a large range of diverse models, so it is better to use the tip. When choosing a exhaust device, several factors are taken into account:

These indicators will help to determine the choice. You can calculate the necessary performance according to the following scheme:

determine the area of \u200b\u200bthe room;
multiply it to 5;
add 20% to the resulting number.

This will be the choice of device performance with a small margin. The alleged change of air indoors is at least 5-8 times a day.

Installing an exhaust device

You can install the fan in the toilet with your own hands, as in the bathroom, you can, if there are already ready-made air ducts. Before starting the installation, it is necessary to check them for blockages, and if necessary, clean the channels with a special jarshik. If the air exchange is not restored independently, it is better to call a specialist who will do it professionally.

With a separate location of the bathroom and toilet, it is enough to put a fan in one of the premises, provided that they are connected by the ventilation hole in the common wall and the air freely circulates between them.

With a wall axial fan, everything is simple - it is installed on top of the ventilating hole:

1. The wall around the entrance to the shaft is missing with polymer glue, silicone or liquid nails.
2. The operating part of the fan is completely intermedible in the hole, and the outer is tightly pressed against the wall.
3. Install the grid and fix the facial cover with self-draws or dowels. Usually they come complete with the device.
4. Put the cable and connect it to the power grid.

Stages of installation work are performed in the following sequence:

1. The cover of the terminal box is unscrewed.
2. The electrical wires are inserted into the retainer, which is located on the lid.
3. The wires are connected to the terminals with the inscription "Linear Phase" and "Zero".
4. The lid put in place.
5. The device is included in the outlet to check the correctness of the connection.
6. The diameter of the air duct leads in accordance with the size of the fan. If necessary, use an additional plastic tube.
7. The instrument is mounted in the air duct pipe at some distance from the grille. To do this, use converted clamps with rubber seals or special flange compounds with adapters (at square section). When attaching, at least 4 bolts are used.

The lattice of the ventilation hole is placed in place, and the wires are closed with a special box to protect them from moisture.

Some people in order to save electricity prefer to automatically turn on the fan when lighting light in the bathroom or toilet. The operation of the device in this mode may not be enough to maintain the optimal microclimate. This must be considered when connecting wires with a switch.

In the absence of confidence in their own forces, it is better to contact the specialists. They will quickly solve the problem of ventilation and carefully fulfill all the work in compliance with the rules and norms.

When installing a mixed system (natural and forced), you must have two exhaust holes. In one of them a fan will be installed. The mixed supply-exhaust system is used in large rooms, with high humidity, where there is not enough ordinary supply ventilation.

For each bathroom characteristic is an elevated level of humidity. In order to prevent such a phenomenon as the formation of mold or fungus, it is worth checking the self-functioning of the ventilation system or install additional equipment. Very often, many people arise how to make ventilation in the toilet with their own hands.

Check ventilation operation Simple: the paper sheet applied to the ventilation hole should not fall.

In order for the mold on the surfaces does not occur, there are several options to combat it:

insulate all surfaces - this method will prevent the formation of condensate;
a very efficient method is a device forced ventilation.

Cleaning natural ventilation

To clean the ventilation from dust, garbage Use the rash with a long flexible handle.

If a natural ventilation system is bad in the toilet, it is necessary to clean the channels. To do this, it is from the channel to eliminate all the accumulated dust and web. To carry out such a procedure, it is worth using a rash with a long flexible handle.

Specialists who are engaged in cleaning ventilation channels can use a more dangerous purification option, which uses a gas can be used with flammable liquid. This method involves burning dust. To conduct such a procedure independently, not having experience, is strictly prohibited, it is better to entrust all specialists.

Forced ventilation

In order for high-quality air exchange in the toilet, it is worth doing ventilation that will work automatically. It is very important for the air with heavy smells and evaporation to penetrate the living quarters. Forced need to be equipped with its own exhaust channel. Before the owner will be presented to the selection of ventilation systems of the ceiling and wall species.

Diagram of the device of general ventilation in the bathroom and toilet.

For the premises of the toilet it is worth picking up a suppressive ventilation system as forced ventilation. Such a system will regularly circulate the air indoors. In addition, it does not imply the cutting of additional ventkalanal, which subsequently can break the strength and reliability of the wall.

Ventilation in the toilet, with your own hands constructed, the case is quite simple, the main thing is to understand all the nuances. The need to make ventilation often arise at the time when natural ventilation does not fully fulfill its basic functions.

This problem is especially manifested in the summer, this is due to the fact that the temperature outside and indoors is almost the same, and the Bernoulli effect does not work. Also, the deterioration in the work of natural ventilation is due to the fact that plastic windows are installed in apartments and homes, which are hermetically closed the premises and prevent fresh air penetration. Also, the doors that are tightly closed, prevent air penetration into the room of the toilet. This problem is especially traced on the upper floors of high-rise buildings, where the temperature in the summer is significantly higher than in the room. It is less noticeable to this problem on the lower floors, where the temperature difference remains even at minimum indicators.

As an option, an automatic exhaust system can be installed, in which case the air will be forcibly output from the room outward. But it is worth considering, due to the lack of air in the premises of the maximum efficiency of such a system, it will not be achieved.

The best option is to make ventilation in the toilet of the supply and exhaust type.

What may be required in the process of work

Fan connection diagram to light switch.

In order to make ventilation in the toilet with your own hands, it is worth purchasing all the necessary tools and materials. Everything you need can be bought in a special department of the construction store. Buying everything at once, after pre-reaching the plan for which the forced ventilation system will be mounted.

Examples of materials to create forced ventilation:

corners are tin - today they are represented by various forms;
plastic box;
air ducts are flexible, which are made in the form of flexible aluminum pipe;
plastic pipes corrugated;
plastic ducts flexible;
fans;
recoverators.

In order to carry out installation work on installing the ventilation system, it is worth preparing the necessary inventory:

roulette and labeling pencil;
hacksaw and scissors;
construction knife;
hammer to clog dowels;
drill and screwdriver;
screwdriver with different nozzles;
fastenings - dowels, screws, self-tapping screws.

In winter, it is very important to equip the ventilation system with supply valves.

This element is a conventional hole in the wall with a nozzle with one or two sash. The location of the sash can be performed manually or an automated way. For maximum comfort, such a hole is located behind the convector or heating radiator.

This location contributes to an increase in thrust and simultaneous heating of air. This will allow you to use the ventilation system without additional fans. One valve is enough to ensure normal air exchange in one room. In order to protect the room from the penetration of garbage, it is worth installing the grille.

Application of recuperators in the ventilation system

For the premises of the toilet, it will still be the best option to equip a special fan system, which will significantly improve the performance of the entire system. This is especially necessary for the summer period. Modern technologies go ahead, and one of the modern elements that the ventilation system can be equipped is a recuperator. This device will circulate air regardless of weather conditions on the street. In order to establish the supply and ventilation system, it is necessary:

The diagram of the supply and exhaust installation with heat recuperator and air filtration.

4 holes that are connected in pairs with special components "Street - Room", "Room - Street";
the main essence of the system is that clean air is taken directly from the street and enters the premises, and the worked output is outward;
recuperators are equipped with special filters that purify the incoming air from dust;
recovers operate automatically either using the control system.
