How the air conditioner works: the principle of operation of the air conditioner, its device and technical diagram

Installation of precision air conditioners

installation

The installation of any precision air conditioner requires detailed planning and extensive experience from the craftsmen. It goes through several stages:

1. Selection of a place for installation, taking into account the location of heat sources, surrounding objects and protective mechanisms (visor and grating). The allowable length of the route and the height differences between the blocks are taken into account.
2. Reliable fastening of the outdoor unit on the brackets, taking into account vibrations during operation. Be sure to leave access to the module for maintenance.
3. Reliable fastening of the indoor unit, taking into account the distance from heat sources and other objects in the room. Provide space for normal air circulation. The slope of the module is allowed no more than 5%.
4. Laying interblock communications. Holes are drilled in the wall through which the drainage hose, freon route and electrical cables will pass. If it is necessary to exceed the allowable line length and elevation differences, it is necessary to install trap loops on the pipeline in order to reduce the load on the compressor. They monitor the quality sealing of the route and the insulation of cables. All communications are packed in a special pipe and vinyl tape, and then dragged through the holes in the wall.
5. Connecting a precision air conditioner according to the electrical diagrams that are given in the technical data sheet, as well as printed on both units.
6. The last stage is the evacuation of the system and a trial run of the installation.

Scheme of the air conditioner device

Despite the huge number of models, all air conditioners have similar basic structural elements. They differ only in external forms and installation features of a particular design.

Each the air conditioner consists of a fan, evaporator, throttle, compressor and condenser. The compressor is designed to compress freon for the purpose of its further circulation in the system. With the help of a condenser, freon is converted from a gaseous to a liquid state. Most often, an external block is used to install this element.
The work of the evaporator is to convert liquid freon into gas.Thus, its functions will be opposite to the capacitor. The throttle allows you to reduce the pressure of freon, and the fans provide direct cooling of the system. The operation of the device does not depend on where the air conditioner is installed - on the wall or on the ceiling.

Varieties of air conditioners

Types of air conditioners

There are several types of air conditioners, although the principles of operation are the same for all. According to the type of air intake, such systems can be conditionally divided into:

• supply;
• recirculation;
• air conditioners with recovery function.

Recirculation systems work with internal air, supply systems use external air masses, and systems with a recovery function use both of these methods.

In addition to this differentiation, there is another division of air conditioners:

1. Monoblock - systems consisting of one block, in which all functions are combined. They are very easy to use, easy to repair and last a long time. Such air conditioners are unpretentious. Their only disadvantage is their high cost.
2. Split systems consist of two separated blocks. One of them is placed outside the building, and the second indoors. Both parts of the system are connected by a tube through which freon circulates. The fan and evaporator of such an air conditioner is located in the indoor unit, and the rest of the system is in the external unit. Between themselves, split systems differ in shape: there are floor, ceiling, wall air conditioners of this type.
3. Multi-split systems are distinguished by the fact that they have several internal blocks, and the external one is still one. Such air conditioners can also be floor, wall or ceiling.

Kinds

Precision air conditioning systems are conventionally divided into several categories, depending on:

Numbers schemes of precision conditioning.

a) single-circuit;

b) Double-circuit.

Executions.

a) On ceilings (with a power of 4-15 kW) are placed in rooms with a small area;

b) Cabinet. It is used in large rooms (with a power of up to 100 kW). Outdoor module as separate condenser;

c) Precision air conditioner - monoblock (with a power of about 20 kW). It has two evaporators and a compressor in one housing.

Cooling heat exchanger.

a) Air. It works on the principle of a split system, consisting of two blocks: an outdoor unit (a compressor with a condenser in one housing) and an internal evaporator;

b) water. Combination of the module with a refrigeration unit (chiller) when the temperature drop is due to the liquid cooler;

c) Combined.

In addition, depending on the type of temperature range maintenance area and the number of circuits in the initial state, climate systems differ in their functioning.

Precision cabinet type air conditioners

System design

• Fan section. Purpose - to provide atmospheric air intake and supply to air-conditioned areas. Centrifugal devices are used.
• Cooling section. A heat exchanger consisting of copper tubes through which water or freon circulates. In the first case, the external source of cold is the chiller. When freon is used as a refrigerant, the module is connected to the compressor and condenser unit.
• Filtration section. The function of the module is to clean the injected air. There are two groups of filters involved in the air conditioner: primary and secondary.At the initial stage, cleaning takes place with devices of the EU1-EU3 class, which remove up to 60% of dust. The second stage is the use of fine filters EU5-EU6, which retain 90% of pollution. The catching elements are mounted on a frame with a seal. Central air conditioning units are equipped with synthetic pleated, bag, absorption, deodorizing filters.
• heating section. Structurally, it resembles a cooling module (consists of tubes). It is completed with water, steam or electric heater.
• humidification section. The module is a steam humidifier or spray chamber with a nozzle. The passing air is saturated with fine water suspension. After the section, a drop eliminator is installed to prevent moisture from entering other parts of the equipment.
• Noise reduction section. To reduce the intensity of noise, sound-absorbing plates are installed. They are made of several layers of mineral wool or fiberglass. The plates muffle the operation of the fans.

How does the air conditioner work for heating?

Existing air conditioners capable of heating in winter are usually equipped with a four-way valve. This valve, switching, causes the refrigerant to heat up from the atmospheric air, and, on the contrary, to give off heat to the room. This is a very economical way of heating a building, since most of the energy is spent not on actually raising the air temperature, but on transferring heat from the street to the house.

On average, heating a room with an air conditioner is about 3 times more economical than heating a home with electrical appliances that are equipped with heating elements (thermal electric heaters). How to set the air conditioner to heat is described here.

However, it should be noted that the colder it is outside the window and the warmer it should be in your room, the less air conditioning is suitable for this. At a frost of -15 and below, a household air conditioner usually can no longer ensure the transfer of heat from the street to the house, since:

• The air conditioner was originally designed for cooling, therefore, in the mode of warming up the home, its efficiency drops along with the ambient temperature.
• Modern environmentally friendly refrigerant is also not designed for frost.
• It is difficult for the compressor to work in cold weather - the lubricant becomes too dense.

Many split systems have automatic switching between “cold” and “heat” modes, regularly switching to the room cooling mode (with the general “heat” mode), but without the fan inside the building. This is done to warm up the radiator in the external unit of the system so that it does not become covered with ice from condensate and does not lose its ability to efficiently heat exchange.

In split systems, there is also an unpleasant possibility of freezing the drain hose. Water, turning into ice, forms a plug inside the hose. Further flow of water from the air conditioner will no longer take place outside, but into the room.

After getting acquainted with the whole variety of types of this climate technology, it will be much easier for you to choose an air conditioner for your needs. Of course, in this case, it is worth proceeding from the type of room that needs to be cooled, as well as from financial possibilities.

Relationship between the driver's well-being and the microclimate in the cabin

All manufacturers pay attention to the issues of ensuring comfortable conditions for staying in a car.According to the results of numerous studies, it has been established that the most comfortable climatic indicators for the driver/passengers is the temperature in the range of 18-20°C at a humidity level of 40-70%

Lowering the temperature to 10 - 15 ° C leads to hypothermia of the body and a slowdown in mental and physiological processes. An increase in temperature to 25 ° C and above leads to increased fatigue, a decrease in concentration, and the appearance of signs of drowsiness. A further increase in temperature to 30 ° C becomes dangerous - the driver's coordination of movements is disturbed, the reaction becomes slow, the ability to adequately assess the traffic situation is sharply reduced.

The ventilation system, in principle, is not able to control the microclimate - in hot weather, when driving at low speeds (for example, in city traffic), it becomes generally useless. Only air conditioning can save, so drivers whose cars are not equipped with a modern air conditioning system are thinking about installing it. Since their vehicle is not designed for this, at least basic knowledge of how this device is arranged and works will be required.

Benefits of an air conditioner

Benefits of the device

The conditioner creates optimum temperature conditions in the house and office. Recently, complex systems with the function of ionization and air humidification have even appeared. It has a very beneficial effect on people, but on condition that the system is looked after. Because air conditioners, like any other devices, require cleaning and regular repairs.

Dirty air conditioner filters are unlikely to make it work useful. There are cases when, due to neglected split systems, people had various ailments.If the owner of such a device wants to get the most out of it, then he must carefully monitor the condition of the air conditioner.

Air conditioner operation

All components of the unit are connected to each other by copper pipes and thus form a refrigeration circuit. Freon circulates inside it with a small amount of compression oil.

The air conditioner device allows you to perform the following process:

1. A refrigerant enters the compressor from the radiator at a low pressure of 2-4 atmospheres and a temperature of about +15 degrees.
2. When working, the compressor compresses freon to 16 - 22 points, in connection with this it heats up to +75 - 85 degrees and enters the condenser.
3. The evaporator is cooled by an air stream that has a temperature lower than that of freon, as a result of which the refrigerant cools down and is converted from a gas to a watery state.
4. From the condenser, freon enters the thermostatic valve (in household appliances it looks like a spiral tube).
5. When passing through the capillaries, the gas pressure drops to 3-5 atmospheres, and it cools down, while part of it evaporates.
6. After the expansion valve, liquid freon enters the radiator, blown by air flow. In it, the refrigerant is completely converted into a gas, takes away heat, and therefore the temperature in the room decreases.

Then freon with low pressure moves to the compressor, and all the work of the compressor, and hence the domestic air conditioner, is repeated again.

Operation of the air conditioner in the cold

The nuances of the work of various types

The split system is executed in wall, channel, column, floor, multi-split and cassette-ceiling versions. The outdoor unit is common, the number of indoor units may vary.The most difficult of all options is a ducted air conditioner: it requires the installation of closed supply and exhaust ducts that do not communicate with the street. A multi-split system needs a tree-like "route" - here the external unit works for several internal ones. Column and floor air conditioners are placed on the floor in the corner, but the "route" is significantly lengthened - the outdoor unit cannot be hung at a height of less than 2.5 m.

However, all split systems work the same way.

Next, watch a video about the device and the principle of operation of the split system.

How split systems work and their varieties

Split system consists of outdoor and indoor units. The outer one contains the compressor, control board, fan and condenser. The main elements of the indoor unit: evaporator, fan, filters, temperature sensors and condensate pan.

Freon circulates in a closed circuit. It consists of:

• internal coil - evaporative heat exchanger;
• external coil - condenser heat exchanger;
• connecting copper tubes - freon line;
• a compressor that increases pressure;
• capillary tube in household systems;
• thermostatic valve (TRV) for semi-industrial units.

Air conditioners that can carry out air heating have a 4-way valve that functionally changes two heat exchangers in places - the outer one is responsible for the evaporation of the refrigerant, and the inner one for its condensation.

Cooling work

Freon enters the compressor, where its pressure increases by 3 times, and the temperature rises by 50-60 ° C, that is, compression occurs.Then it follows into the condenser and is blown with colder air, after which it passes into a liquid state. The air passes through the condenser heat exchanger and is heated by the heat released by the freon.

The refrigerant then moves into a spiral capillary tube, or expansion valve, where its pressure is reduced, the temperature is lowered, and a slight evaporation occurs. The evaporative heat exchanger is purged with room air, but cools down when colder freon enters. The refrigerant at the same time takes away its heat and goes into its original state. Then the cycle repeats.

Heating work

The essence of the principle of operation of a split system air conditioner for heating does not change. When the 4-way valve switches the functions of the units, when the direction of the refrigerant flow changes, the air is taken from the street by the outdoor unit, where the freon evaporates, and the indoor unit delivers it to the room, in which the refrigerant again passes into the gaseous phase.

The lower the outdoor air temperature, the more difficult it is to extract heat from it, since the difference between the air temperature and the freon evaporation temperature decreases, therefore, the heating capacity decreases due to the alignment of their values.

Precision air conditioners

Precision climate technology according to the principle of operation does not differ from a split system, but has a number of features:

• Able to work in 24/7/365 mode for 10 years, while a household split system will last no more than 2 years.
• It has a powerful fan, due to which the cooling quality is higher than that of a split. Air streams of the set temperature are evenly distributed on the room.
• Freon, water or glycol can act as a working substance.
• Air humidification is carried out using an electrode-type steam generator.

Precision air conditioners are used in server rooms, where it is necessary to continuously maintain a certain temperature and humidity.

inverter air conditioners

The principle of operation of an inverter air conditioner is the same as that of a conventional one. The difference between the climatic equipment of the inverter type lies in the control of the operating mode. In a conventional split system, when the set temperature is reached, the compressor turns off. When the temperature changes upwards, the blower starts. Thus, the system works at full capacity, but with interruptions.

Inverter motors have a frequency converter board that changes the standard frequency of the electrical network. The fan does not stop working when the temperature norm is reached: it gradually slows down the rotation, and when the air is heated by 1 degree, it increases the number of revolutions per unit time.

The advantages of such control are in the durability of the equipment and in saving electricity up to 30% compared to non-inverter split systems.

Channel climate system

A system of inlet and outlet air ducts departs from the indoor unit of the ducted air conditioner, through which warm air is taken in and cold air is supplied to one or more rooms.

Equipment of this type has the function of mixing fresh air from the street up to 30%.

Installation of a duct-type air conditioner is best done at the stage of building construction - the unit is installed under the ceiling along with the ventilation system.

Elimination of possible malfunctions of air conditioners

During the operation of cooling systems, various minor breakdowns and malfunctions may gradually appear. For their successful elimination, it is necessary to clearly understand the principle of operation of the air conditioner in order to quickly determine the location of the defect.

Many violations occur as a result of water hammer that occurs after liquid freon enters the compressor. The agent, being in the evaporator, does not have time to completely go into a gaseous form. This violation often occurs due to incorrect design of cheap air conditioners. Here, the slightest temperature differences cause a malfunction. In addition, water hammer occurs due to dirty filters.

A frequent violation is freon leakage associated with improper installation of tubes or as a result of factory defects. The malfunction is determined by the state of the rear wall of the device, which begins to freeze.

Manufacturers overview

In our country, you can buy ducted air conditioning from at least 60 different manufacturers. Among the inverter split systems, Hisense AUD-60HX4SHH stands out favorably. The manufacturer guarantees an improvement in the condition of the air in an area up to 120 m2. Smooth power control is provided. The design allows for pressure up to 0.12 kPa. The allowable amount of passing air reaches 33.3 cubic meters. m for every 60 seconds. In the cooling mode, the thermal power can be up to 16 kW, and in the heating mode - up to 17.5 kW. A special mode has been implemented - pumping air for ventilation without changing the air temperature.

Optionally, you can use both the supply mixing mode and air drying.The option of automated temperature maintenance and self-detection of problems is available. This ducted air conditioner can be commanded using the remote control. The designers provided for the use of a timer to start and turn off the device. Uses R410A coolant to move heat. This type of freon is safe for both humans and the environment. The device can only be connected to a three-phase power supply.

If a duct-type inverter air conditioner is required, Mitsubishi Heavy Industries FDUM71VF/FDC71VNX may also be an alternative. Its execution is curious: there are both floor and ceiling components. Thanks to the inverter, a non-sharp change in power is supported. The maximum allowable length of air ducts is 50 m. The main modes for this model are air cooling and heating.

The minute flow in the duct can reach 18 m3. When the air conditioner cools the atmosphere in the room, it spends 7.1 kW of current, and when it is required to increase the temperature, it consumes already 8 kW. It makes no sense to count on functioning in the supply fan mode. But consumers will be pleased with the modes designed for:

• automatic temperature hold;
• automatic problem diagnosis;
• operation at night;
• air drying.

As befits good modern technology, a product from Mitsubishi can remember previously set settings. The lowest outdoor air temperature at which the cooling mode is maintained is 15 degrees. 5 degrees below the mark, after which the device will not be able to heat the air in the room. The designers took care of the possibility of connecting their product to smart home systems.The linear dimensions of the inner part of the duct air conditioner are 1.32x0.69x0.21 m, and for the outer part or window compatible unit - 0.88x0.75x0.34 m.

Another noteworthy device is the General Climate GC/GU-DN18HWN1. This device is designed to be connected to air ducts no longer than 25 m. The maximum static pressure level provided is 0.07 kPa. The standard modes are the same as for the previously described devices - cooling and heating. But the throughput is slightly higher than that of the Mitsubishi product, and is equal to 19.5 cubic meters. m per minute. When the device warms up the air, it develops a thermal power of 6 kW, and when it cools, 5.3 kW. The current consumption is 2.4 and 2.1 kW of current, respectively.

The designers took care of the possibility to ventilate the room without cooling or heating it. It will also be possible to automatically maintain the required temperature. On commands from the remote control, a timer is started to turn off or turn on. The volume level during operation is not adjustable, and in any case is a maximum of 45 dB. The work uses an excellent safe refrigerant; The fan can spin at 3 different speeds.

Carrier 42SMH0241011201 / 38HN0241120A can also show very good results. This duct air conditioner is able not only to heat and ventilate the room, but also to rid the home atmosphere of excessive moisture. Air flow is maintained through a special hole in the housing. The control panel included in the delivery set makes it more comfortable to work with the device.The recommended serviceable area is 70 m2, while the air conditioner is able to operate from a conventional household power supply, and its small thickness allows it to be built even into narrow channels.

The device of the air conditioner on the example of a split system

Despite the fact that the split system consists of indoor and outdoor units, according to the principle of operation, it repeats the device of any other type of household air conditioner, because it is based on a completely sealed closed circuit filled with refrigerant, consisting of heat exchangers connected by copper tubes. The heat exchanger in the indoor unit is called the evaporator and the heat exchanger in the outdoor unit is called the condenser.

The refrigerant, flowing through the system, transfers thermal energy between the heat exchangers, all this happens thanks to the compressor located in the external unit. For efficient heat exchange between the refrigerant and air, fans are installed in each of the blocks that drive air through the heat exchangers. Another important unit of the device is a throttle device, it is installed in the indoor unit in front of the evaporator and is necessary to reduce the pressure of freon in order to convert the latter into a gaseous fraction.

The whole process of air conditioner operation in air cooling mode is as follows. The compressor in the outdoor unit pumps the refrigerant, increasing the pressure in the condenser heat exchanger, which causes it to become liquid, which is accompanied by the release of heat, which is removed into the air due to the operation of the fan.

The cooled refrigerant enters the indoor unit through a copper pipeline, where, passing through a throttle device, it boils, turning into a gaseous state, absorbing heat, and greatly cools the evaporative heat exchanger. The fan of the indoor unit blows the air taken from the room, which is cooled and returned back. At the same time, moisture condenses on the evaporator plates, which is discharged through a plastic tube into the sewer or outside. Then the refrigerant returns through the copper pipe to the compressor and the cycle repeats.

Some air conditioners can operate in the mode of heating the air in the room; for this, the outdoor unit of the split system has a four-way valve, through which freon moves in the opposite direction. In this case, the condenser becomes an evaporator and the evaporator becomes a condenser.

What is a refrigerant?

A refrigerant is a substance that can easily change from one state of matter to another. Circulating along the circuit of the system, ensures the correct operation of the air conditioner.

Some time ago, chlorine-containing freon R12 was used in air conditioners. However, this substance had a negative impact on the ozone layer of the atmosphere. Therefore, in all cars manufactured after 1993, fluorine-containing R134a began to be used. Substances of these two types are incompatible.

There is also a new generation - R1234yf. It is the most environmentally friendly refrigerant, but is flammable. Until 2017, car air conditioners rarely adapted to a new refrigerant. However, today many countries have begun to gradually switch to R1234yf.

Advantages and disadvantages of precision air conditioners

Precision air conditioners belong to the category of high-precision equipment, or rather, reliable and durable devices with high power. The purchase of such a unit will definitely solve the problem of controlling the temperature regime in the room.

Advantages of precision devices:

• The ability to maintain an accurate temperature threshold. In average air conditioners of this type, the change step is 0.5 degrees.
• Humidity control within 3%. Exclusively for appliances with built-in humidifier.
• The ability to run smoothly without the need for a shutdown or any kind of reboot.
• Many models have an additional backup unit that starts functioning after the main one is turned off.

Modern server room and a range of precision devices

These devices also have their drawbacks, which include:

• Too high pricing policy. Precision air conditioners are difficult to manufacture, require a lot of components and appropriate assembly and tuning specialists. Therefore, each device has a high cost.
• Complicated installation. To connect precision devices, you should call in specialists who will not only deliver the air conditioner and install it, but also set up its operation.
• They have large dimensions. Which implies appropriate transportation and delivery to the installation site.
• Not designed for home use. The relevance of using only as a source of cooling for technical or technological premises.

The device and principle of operation of a conventional air conditioner

The air conditioning unit is a rather complex and capricious device that requires careful handling and constant care. Freon is usually used as a special substance that provides cooling and heating. The essence of the operation of the system lies in the ongoing physical reactions inside, more precisely, the reactions of the liquid. Evaporation of water means absorption of heat, and condensation means release. Since the peculiarity of the operation of the unit is the evaporation and condensation of the refrigerant, its device is in many ways reminiscent of the behavior of a refrigerator. Changing the values ​​of pressure and temperature leads to the desired effect - cooling or heating of the building.

Important! Some users believe that the principle of operation of a split system is to take in street air and then return it to the room. This opinion is wrong

Models that can mix in fresh outdoor air are extremely rare and very expensive.
Scheme of the air conditioner device

How air is cooled and heated with an air conditioner

The operation of the system is a closed cycle. Cooling and heating are two mutually inverse processes, so you can understand the principle of operation of the device by familiarizing yourself with only one of them.

During cooling mode, the following actions occur:

1. The compressor is turned on, which builds up pressure;
2. The coolant in the gaseous state begins to pass through the radiator, becoming liquid and hot;
3. In this state, the refrigerant enters the expansion valve, where its temperature begins to drop;
4. This leads to the evaporation of the refrigerant, as a result, the evaporator is covered with a cold gas-liquid mixture;
5. The fan blows cold from the evaporator, directing cold air into the room;

6. Freon, which has turned back into a gas, enters the condenser, and the cycle is completed.

When heated, the reverse process occurs - instead of evaporation, the coolant condenses.

Healthy! Air conditioning units consume a lot of electricity, since their operation is based on an engine and a compressor. On the other hand, the energy consumed is three times less than the transformed one, and therefore the use of an air conditioner as a heater is considered more cost-effective than the use of specialized equipment.

2 Operating tips

The compressor in an air conditioner can fail because the evaporative element cannot handle the coolant. If you follow some rules of operation, you can avoid breakdowns:

• do not turn on the device in severe frost;
• the appliance is designed so that it can operate above only the manufacturer's lower limits;
• the purpose of the device is to cool the temperature, but between seasons it can be used to heat rooms;
• the load is reduced when windows and doors are closed;
• if it is necessary to ventilate the room, then the air conditioner is turned off;
• periodically clean the boilers, filtration systems, replace damaged parts;
• for air conditioning, in principle, the minimum temperature is not set, as this overloads the compressor;
• do not use the equipment at home in very hot weather;
• for a faster decrease in temperature, increase the number of fan revolutions.

4 Advantages and disadvantages

The main advantage of such devices is the ability to control the microclimate of the room and create an atmosphere that is optimal for a person. It is possible to adjust many parameters that will significantly increase both the comfort of living and mood, productivity and well-being. Therefore, it is desirable to install air conditioners not only in apartments, but also in workplaces.

One of the main tasks of these devices is air cooling in summer. This may be required in conditions where natural ventilation is not available, for example, it is too hot outside the window or the temperature difference between the street and the room is too large and dangerous to human health. In addition, such devices can be used in rooms, the production standards of which prohibit opening windows or they simply do not exist there.

These devices have other useful features. They can be used to clean the air of unpleasant odors, for which they are often installed in the toilet or in the kitchen. In addition, they are able to control the degree of humidity or dryness of the air, which is useful in regions with too wet or arid climates.

However, they also have some drawbacks. There are suspicions that they can adversely affect human health. Sometimes this is true. Many people think that air conditioning is a source of bacteria and viruses. If the system has not been cleaned for a long time, then it can really pose such a danger. But the fact that air conditioners kill the air, removing all useful elements from it, is not true. If the apparatus is cleaned, then, on the contrary, it filters the air, and all oxygen enters the room.

The real problems with air conditioners are due to the fact that some of them are very noisy, and a direct stream of cold air can lead to a cold. But it is also possible to cope with them: you just need to avoid direct blows on yourself by choosing the appropriate mode or adjusting the blinds, and you can choose the most silent model. Then the air conditioner will cause only positive emotions.

What is the difference between air conditioner and split system

Many buyers ask what is the difference between window, floor and split type cooling products? The second option is considered more functional and efficient. Any split system has the following advantages:

• the evaporator can be placed on the ceiling, wall or on the floor, while it is ideal for any room interior;
• cooling is faster due to the greater power;
• cleans, moisturizes and ionizes the injected air;
• during operation produces a fairly low noise impact on others.

For an apartment with a large area or a suburban building, multi-systems with several internal evaporators and one remote unit are purchased, which makes it easier for users to operate the entire process. In addition, the appearance of the cottage does not spoil the abundance of remote blocks of the same design, but with different noise exposure.

The device and the principle of operation of the air conditioner are no different from the device of any split system, the difference is only in specific nuances, therefore it is very difficult to give an exact answer which equipment copes with the tasks better - each of them has its own disadvantages and advantages that determine the scope of their application .

The structure of window-type air conditioners is distinguished by a peculiar design - one part of them is inside, and the other is outside the window unit. With a monoblock floor version, they are similar only in design, since all components are inside one case. Working parts - a fan and a compressor - make more noise than a split system, because they have these components in a separate unit located outside the room.

Before making a choice when buying such a product for your home, you need to compare the technical characteristics of the most inexpensive split systems with similar parameters of a floor or window type of device - there are many positive and negative nuances for each type, so it is very difficult to draw a final conclusion.
