Air conditioning with heating and cooling function. Heating and heating conditioner of a country house - features, dignity and disadvantages. Cooper & Hunter Heat Pumps

The company has spread the opinion that the air conditioner is intended only for the cooling of the room. At the same time, most people know about the functions of heating inherent in many models of split systems. But the attitude to such a function, to put it mildly, not confidential. People buy such systems, but very rarely use the heating of the room with air conditioning in the cool time of the year. The sellers of climate machinery themselves serve as a source of information on the undesirability of the use of air conditioners when the thermometer on the street is lowered below zero. With such a situation, it is necessary to understand in detail in order to be able to apply all the advantages of the described aggregate. In this article, consider all the necessary parameters of the competent use of the air conditioner in the winter. Let's touch the criteria for the correct inclusion and operation of the device under such conditions. The main thing is to prevent technical errors with similar use of the split system.

Characteristics of the air conditioner in the "Heating" mode

The features of the design of the split system imply the absence in it heating element. Just the operation of the air conditioner to heat will not give a full result when a decent frost is on the street. Such a device can fully heat the room only if the temperature outside the window has certain values.

To select a high-quality model, it is better to draw your opinion on inverter modifications. All of the above characteristics in them are much more preferable. In addition, there is significant energy savings.

Traditionally, it is believed that the heating of the room with air conditioning in the winter - the lot of warm countries, where the minimum January -5c temperature is. The opinion "Air conditioning is not included in the winter can not" extends to the sellers and installers themselves, because in the manufacturer's catalogs, the minimum temperature of the air conditioner in the winter to -5c is really indicated. But how objectively is it?

Is it possible to turn on the air conditioner in winter?

To the minimum temperatures specified in the documentation by the manufacturer - of course you can. After all, it is not easy. Manufacturers add the possibility of working conditioner to heating in winter, so-called. The function "Thermal pump".

What air conditioners can be included in winter?

Any, but to the temperature indicated in the passport, is usually -5c. If you want to turn on air conditioning for heating in winter at more low temperatures - It will take refinement of the air conditioner for work in the winter, the so-called winter package for air conditioning.

At what temperature can air conditioning in the winter?

With a street temperature above -5С, additional preparation of any air conditioner is not required for winter. In most inverter split systems, the lower threshold of the air conditioner work on heating in the winter is usually-15c.

Does the semi-sensitive air conditioner work in the winter at 30?

Semi-industrial models - this is also split systems that differ in type internal block, improved compressor, increased heat exchanger area and additional protective features. Therefore, they easier tolerate extreme winter loads and are less losing in performance at low temperatures, compared to household series. The only thing that can prevent the work of the semi-industrial air conditioner in winter to heating - built-in electronic protection by outdoor temperature On some models. In each case, you need to watch the documentation for this block.

Is it possible to heat the air conditioning in the winter?

Yes, almost all modern models have such an opportunity. Air conditioning in heating mode in winter works as an air thermal pump, i.e. "Air conditioning on the contrary." The outer block "takes heat" from outdoor air and gives it to the room. But the lower the outdoor temperature, the smaller the efficiency (after all, the heat in the street air becomes less). Even inverter air conditioning in the winter produces efficiency\u003e 1 only to temperatures -15С / -17С. With lower street temperatures, it can work, but the effectiveness will be comparable to the usual ten.

Air conditioners with heating in winter up to 25

Special series of winter split systems are produced with a factory low-temperature kit, for example, a series of Japanese manufacturer Fujitsu General. Designed for Scandinavia, she regularly issues efficiency\u003e 2 to -25s. But such winter split systems are more expensive than ordinary inverters.

To which temperature can air conditioning in winter?

If a outdoor block Installed on the street, but modified by the "winter air conditioner package", then it can be turned up to -30c, although the efficiency of the system at temperatures below -15С will not be higher than 1: 2 (depending on the model).

To use air conditioning in winter to heating at any street temperature, the outer unit can use the heat that is lost by the building through the enclosing structures or exhaust ventilation.

Heated with air conditioning in winter pluses and cons

You can use the air conditioner in the winter in the apartment, but in the presence of central heating, it is hardly advisable. The apartments usually include air conditioning on heating only in the offseason, when the temperature outside is close to zero, and central heating Not yet included.

Other thing - a private house. With the right project and installation, air conditioning can be the main source of home heating.

Benefits of operation of air conditioning in winter for heating:

1) Electricity savings. The average energy efficiency coefficient for the heating season is 1: 3. This means that the air conditioner will spend three times less electricity compared to Heating by the Tanni or electric boiler. For energy corrective areas, this can be critical.

2) Safe coolant. Turning off the electricity in the house with an electric concrete will result in the defrost of pipes and the inhabited repair of the heating system.

3) Fireproof. Freon air conditioners non-combustible, and even if the house is deployed, the house does not suffer.

4) Remote control. All modern Japanese air conditioners support the ability to control over the Internet (using additional devices), as well as maintenance of temperature +10 to save electricity when heating country houses.

5) Air conditioning in summer. Without additional expenses in the summer you get the cooling system at home.

Of the minuses, you can only be called one - the price, compared with the simple gas boilers.
But if there is no gas in the village and there are limits for electricity, then there is no alternative to air conditioning in the winter for heating.

Heated with air conditioning in winter personal experience

Famous journalist-freelancer Viktor Borisov has been blogging at home for several years now.

As the only heating system, he chose a channel inverter. In his blog, he shares the experience of the air conditioner in winter to heating for four years (http://victorborisov.livejournal.com/281859.html).

Particularly deliver some comments "Specialists in air conditioning." How often in life happens, people do not interest the facts that contradict their picture of the world.

Modern split systems can work not only on cooling, but also heat the room in cold period. And also when heating air conditioning, electricity costs will be less than when using heaters.

The principle of operation of the air conditioner in heating mode

All Split systems for heating in winter have the same principle of operation. The unit pumps heat inside the room on the principle of operation of the heat pump. The device occurs in the process of condensing the fluid, which carries the heat from one medium to another.

In the heat exchanger of the inner unit under high pressure condenses freon, which is heated to 80 ° C. After that, already liquid freon goes into an outdoor unit, where it boils and evaporates. Thanks to this principle, it is possible to use air conditioning for the heating of rooms.

Turning on the air conditioner to heating

How to enable split-system for heating:

On the remote, you must click on the power button.
Then you should click on the HEAT button (heat). In the absence of such a button, you need to click on MODE (operation mode) or the button on which the sun, snowflake or fan is drawn.
It is required to select the heating mode.
After selecting the fan turns on and after 5-10 minutes the air will begin to heat up.

Each time you select the mode, the system must flash or output a beep.

Restrictions at the minimum outdoor temperature

Not all models of air conditioners have a heating function. In the instruction manual, it should be indicated, it is possible to include air conditioning in the winter for heating in the apartment. And also, at what temperature you can turn on the split system.

IN winter The difference in air and freon temperature is small. Due to the fact that the heat exchanger of the outer block is colder than the temperature of the outer air, it is formed by anaya that impede heat exchange. If Freon does not have time to evaporate and get into the compressor, the unit will fail.

Limitations at the minimum temperature of the outer air for reversible air conditioners is -5 ° C. For inverter - not more than -15 ° C. It is possible to further equip the split system with a set to work at lower thermometer values.

Models with heating function

Air conditioners manufacturers offer models with heating function:

When choosing an air conditioner, you should pay attention to the noise level, the presence of air filters, an energy efficiency class.

Heating air conditioning in the winter is becoming increasingly popular. This is due to the emergence of a new generation of devices equipped with the "Winter-Summer" function and capable of carrying out full heating of housing. The cost of such devices slightly exceeds the cost of traditional models, but the tools spent quickly pay off in the cold season.

The feasibility of the process

Air conditioners with heating function are constructively different from their older analogues. The devices are equipped with a heat pump, thanks to which they become very economical: one operating air conditioner kilowatt electricity at the output gives from 2.5 to 4.2 kW of heat. The devices are able to effectively damn the room at outside temperatures from 0 to -15 degrees, but more powerful copies easily cope with 30 degrees. For comparison: oil heater, consuming the same kilowatt of electricity, is able to give only 0.95 kilowatt heat.

It follows from this that the means for heating with the help of the air conditioner leaves two times less than when heating the house heater. However, it is advisable to choose air conditioner as a source of heat in only non-geasy regions, or in places where, instead of natural gas, an expensive liquefied propane is used. In other cases, heating with air conditioning is certainly more expensive heating natural gasAnd preference must be given in favor of the latter.

Principle of operation

The process of heating conditioner is fundamentally different from the essence of the heating process with an electric heater. And if the electricity heaters spend directly on the incandescent of the Tan, then in air conditioners - exclusively to the operation of compressor equipment, fans and dampers. The heating principle of air conditioning is to heat the refrigerant in the outer block, with its further injection with the help of the compressor to the indoor unit located indoors. Further, by means of a fan, heated air, the direction of which is determined by the dampers, is supplied to the room and it makes it heating.

Street air heating occurs in the process of lowering its temperature. For example, the air conditioner took the air at a temperature of -15 degrees, and gave it back to the street in an even more cooled condition, with a temperature -25. The difference of 10 degrees was used for heat transfer, as a result of which heated air was formed, which was filed with a compressor to the internal unit. However, with this method of heating, it is important to regularly monitor the outer temperatures and in no case should the device work if the temperature drops below the maximum permissible. The lower temperature limit is indicated in technical passport Products and cannot be ignored by the consumer.

Otherwise, the technique will start working for wear and quickly fails. However, the latest models of air conditioners with the heating function are equipped with a special unit that warms the thickened oil, which eliminates the risk of overloading compressor equipment and disconnecting the device. The problem of frosting drainage hoses, which was fraught with a condensation in the house. On the modern models Installed low-power heaters, which protect nozzles from moving and do not give condensate to turn into a lot. All devices are equipped with a protective blocking system that will automatically turn off the device in case of lowering the external temperature below the maximum allowable mark.

Pros and cons

The growing popularity of heating rooms with air conditioners due to a number of indisputable advantages of this method:

the principle of heating does not imply the combustion of oxygen, as occurs when the electrical heaters occurs. This contributes to preservation in the room of a comfortable microclimate and eliminates excessive air drying;
heating with the help of the air conditioner is much more economical heating with an oil heater;
easy to control the device and the lack of risk to get a burn allows you to use air conditioning in a house without fear of using small children and animals;
high efficiency exceeding this parameter electrical heaters 2-3 times, it allows you to effectively warm the space, while spending less electricity;
forced operation of the ventilation equipment helps to warm the room almost instantly;

the multifunctionality of the device is due to its use at any time of the year. In winter and in the offseason, the device will work on heating, and in the summer - cooling the dwelling;
fast installation process and wide availability of service;
simple care. It is possible to clean and flush the split system yourself;
acceptable cost. Acquisition of air conditioner with heating function will cost a little cheaper than buying a heating gas boiler;
full environmental Safety The heating systems are due to the absence of CO2 ejection and other combustion products, which, for example, are discharged when burning gas in open-type boilers.

By cons of this type of heating include reducing the efficiency of the air conditioner.which happens directly proportionally down external temperatures. Models capable of working effectively in the range from -15 to -30 degrees are quite expensive. Another disadvantage is uneven warm-up effect. For example, with a high arrangement of split-systems, the floor in the room will remain cold. However, the way out of this situation is still available. For more uniform heating of the entire room, you can purchase climate control sensors that automatically redirect warm streams on the desired areas of the room.

Split systems with thermal pumps

For more efficient work Air conditioner for heating, the system additionally includes heat pumps. The power of the heat pump is designed for each room individually and depends on the size of the room and the air conditioner power. The device equipped with additional heating amplifiers is capable not only to heat the air of the room, but also to provide living hot water. The provision of hot water supply occurs according to the following scheme: Freon, heated as a result of heat transfer, goes to the heat exchanger, where he gives its heat water. Water, in turn, passes through the channel tubes located in the circuit of the thermal pump. Further hot water It comes out of the split system and through the pipeline goes to the consumer. In the summer months, the system works as an ordinary cooler.

The main advantages of split systems equipped with thermal pumps is a high efficiency. So, when consuming one kilowatta of electricity, the device is able to issue 5 kW heat. It is much higher than when heated with air conditioning, not equipped with a thermal pump and operating in standard mode. These complexes received the name of the inverter and have proven themselves as one of the most economical and effective systems Heating. Most devices can be able to operate at air temperature -25 degrees, and their installation does not require complex work In the arrangement of pipelines and chimneys, the installation of radiators of heating and the construction of boiler rooms. The device takes very little space, does not climb the space and harmoniously fits into the modern interior.

In cold and frosty weather for many people, the question of heating their dwellings is relevant. The stationary heating system does not always cope with its functions and cannot provide the optimal temperature in the room. Therefore, more and more people begin to use special climatic equipment in order to warm their house. It is best for these purposes a air conditioner for heating.

Universal split systems that ideally cope with the heating function in winter, have won love from consumers

Modern manufacturers offer universal split systems that perfectly cope with the task of additional heating in winter. Despite the fact that in the domestic market, this equipment recently appeared, it won the confidence of consumers and got nationwide love.

Features of air conditioners for heating in winter

The principle of operation of the split system can be compared with the compressor refrigerator. Air conditioners for heating are equipped with a special ten, which carries out the heated drainage. Split systems consist of two blocks. One block equipped with a fan and compressor is installed with outsideAnd the second with the fan remains indoors.

Both parts are connected to each other. Many systems have a pressure relay that allows you to control the heating of the room. In order to prevent freezing water inside the system, air conditioners for heating in winter are equipped with special safety devices and oil heating function.

What you need to know about split systems

Special attention when choosing a split system should be paid to the power of the equipment. Because this indicator will depend on the productivity of the instruments. The least powerful are household models that are attached to the wall. The maximum power has systems installed on the floor or ceiling.

Another one an important parameter Climatic equipment is temperature modeat which it can work. In most products, the temperature range is from 16 to 30 ° C. In addition, it is worth paying attention to the noise of the air conditioner. For residential buildings, it is preferable to choose models with high levels Noise insulation.

Not all types of climate equipment are suitable for heating in winter. Therefore, before buying a specific model, it is necessary to ask the seller at what minimal temperature values \u200b\u200byou can use climatic equipment.

It is accurately referring to this issue, because most split systems are designed for heating in autumn or spring. Therefore, such systems cannot be used at low temperatures. Because in the frost, they will work on wear and very quickly fail.

Many people do not even suspect that not all split systems are heated. For them, this news becomes an unpleasant surprise when the equipment is already installed, and it is impossible to change anything.

Air conditioning equipped with a winter startup function can be turned on even with negative temperatures (up to -25 ° C)

Air conditioners equipped with a special system for winter start can be included even when the air temperature drops to -25 ° C. The process of managing equipment in the winter period is no different from the summer.

Advantages of air conditioner heating

The main advantages of split systems include:

high productivity;
affordable cost;
multifunctionality;
ability to use at low temperatures.

Modern climatic equipment is characterized by energy efficiency. When using only 1 kW, it gives up to 4 kW.

Thanks to this, air conditioners are significantly superior to energy efficiency electric heating devices. The heating efficiency of the room when using a split system is 3 times more than that of a conventional heater. And the consumption of electricity is insignificant. Such savings is explained by the principle of air conditioning.

All electricity is spent on moving heat, and in electrical heaters it is converted to heat. In many countries, air conditioning heater is used as the main source of heat. It works with full return and creates a favorable microclimate indoor. Thanks to his work in the house dry, warm and comfortable.

Maintenance of split systems

It is necessary to prepare in advance for the first inclusion of the air conditioner in winter time. Particular attention should be paid to filters, because the microclimate in the room will depend on their state. Filters must be cleaned or replaced. The antifreeze is required, because the service life of the device depends on it.

Before the beginning winter operating The system needs to be turned on on ventilation mode and give to work for about 2 hours. During this time, the entire moisture from the indoor unit should go. In order to prevent snow from entering the equipment, it is necessary to protect external block Special casing.

In addition, you must perform all the requirements of the first winter startup system. You can get acquainted with their full list in the factory instruction, which is attached to the equipment. Failure to comply with the manufacturer's recommendations leads to the fact that the equipment works for wear and its performance is significantly reduced.

Periodically, it is necessary to clean the climatic equipment. The frequency of it depends on the conditions in which air conditioner with heating function (contamination and air humidity level).

How to choose a split system

The choice of device is affected by many factors. But first of all, it is necessary to take into account the place in which its placement is supposed. Depending on this, choose outdoor, wall, column, or cassette model. For residential premises small square Suitable air conditioners with a capacity of 2.4 kW.

Mitsubishi is one of best manufacturers air conditioners on the market

Products of Daikin, Toshiba and Mitsubishi are considered the best goods in the climate equipment market. Most models of these brands are equipped with various functions, including heating in winter.

Each person who decided to acquire a split-system for winter use, you need to be prepared for what it is much more expensive (by 30%) than ordinary seasonal models. But the comfortable microclimate in the room and energy savings on the energy resources covers the cost of installing climatic equipment.

We should not forget that the air conditioner is not a heating device, and there is no heating element. That is why he cannot act as the main heating device. To create an optimal temperature in the room in the winter season, the use of one split system will not be enough.
