Put indoor unit air conditioner - not just fit into the interior of the room next to the chest of drawers or above desk near the window. Often, the installation of an air conditioner will be coordinated with the changes planned on the occasion of a complete redevelopment already existing house or apartments or in a newly commissioned new building.
The relationship between power and unit dimensions
The owner of the household or the owner of the work premises knows exactly which model of air conditioner is suitable for him in his particular case. The choice is made not only by the performance of the air conditioner (power, number of modes and other general and auxiliary functions), but also by the dimensions that the outdoor and indoor units should have.
Almost all household owners prefer the split system for its energy efficiency, high cold return and the variety of split types available on the microclimatic equipment market.
The size of the indoor and outdoor units is the main factor affecting the cooling capacity. A small indoor unit is unlikely to have an internal circuit through which the acquiring gas circulates. state of aggregation the refrigerant will turn out to be large enough to produce, say, all the same 15 kilowatts of power according to the heat taken from the room. In a bedroom of up to 25 m2, a cooling power of 2.7 kW is enough to lower the temperature in an hour, for example, from 32 to 23 degrees.
However, in a small range of released cooling power - for example, 2.7 and 3 kW - for models of air conditioners of the same line, the case of the indoor unit may be the same. This comes from stock. inner space, allowing you to place a slightly longer coil. In some cases, an increase in cooling power is also achieved due to somewhat more powerful engine a cylindrical propeller that blows the cold just generated by the circuit into the room. But the "speed" of the fan overclocked to full power, introduces additional noise in the refrigerated room. The diameter of the tubes of the freon line remains unchanged.
Indoor unit dimensions
The typical length of the indoor unit of a split system is an average of three quarters of a meter. Rarity - block 0.9 m long. Installers often measure an average length of 77 cm. Block height - 25-30 cm, an average value of 27 cm is often used. Depth (from the front panel to the wall) - 17-24 cm. Depth is no longer so important here. Practical (installation) length and height - 77x27 cm, which fits into the requirements for apartments.
A compact ceiling module, often having a “flattened” shape on top, has a quadratic design with a side from 50 cm to 1 m. If the unit is channel, then its main part is hidden in the ventilation duct. For floor-mounted column modules, the height is approximately 1-1.5 m, and the width and depth are the same as for small single-chamber refrigerators, for example, 70x80 cm. Because of this, column modules are not located in small rooms.
Whether it is a large-medium or small-sized module, its placement principle may not change, especially for models of the same line. A high power split air conditioner does not have an indoor unit that is too small. Conversely, a low-power split system does not need a roomy unit that is too spacious.
Location
The indoor unit is located in such a way that there should be no obstacles for the intake of heated air from the room and its release in a cooled form. For not quite standard or limited spaces, the size and location of the wall, floor or ceiling unit should not be to the detriment of the people who use such a room. There were cases when, due to the peculiarities of the architecture of the building, the ceiling block was placed on the wall or vice versa. The operation of the coolers does not depend on how it will be located, the main thing is not to flood the electronics of the unit with water condensate formed during operation.
Specific firms from time to time have their own approaches to the placement of room modules of split systems. So, Carrier presented a vertical unit with a side exit of the cooled air. Gree offered corner air conditioners.
Such solutions are popular with owners of small one-room apartments constrained by lack of space.
Finished Size Examples
Yes, the company Gree the depth of the room module is only 18 cm. The length and width here vary, respectively, within 70-120 and 24-32 cm.
At Mitsubishi air conditioners have following sizes: 110-130x30-32x30 cm. Such dimensions are taken for a reason: for high-quality airflow, the radius of a cylindrical fan must be at least several centimeters, and its length must be at least 45 cm.
Chinese air conditioners from the company ballu are the smallest systems. Model BSWI-09HN1 has a unit with dimensions of 70 x 28.5 x 18.8 cm. special significance does not have.
Korean company Samsung produces air conditioners various types. A significant part of the production is occupied by split systems, also on the market under this brand there are both monoblock window models and multi-split systems.
All modern systems this brand's air conditioners are distinguished by:
- multifunctionality;
- energy efficiency;
- low noise level;
- stylish design;
- efficient system air filtration.
The multi-stage cleaning system not only cleans the air stream from contaminants, but also disinfects it, killing bacteria and microorganisms.
Compact windows
The smallest ducts have a block height of 199 mm. These are the so-called low-profile channel-type units, which are produced to work in powerful multi-zone systems.
The usual channel conditioner intended for work in the room of 40 sq.m. m, like the ADH1800E model, has the corresponding power (5 kW) dimensions 1340x260x600 mm.
The indoor unit of the air conditioner is part of the split system located indoors. With its help, the air in the room is heated or cooled, which helps to create the most comfortable temperature conditions for people. This module has many varieties and can be installed in any convenient place. Installation work is carried out quite simply, so even a person without experience can easily cope with this task.
General information
Before choosing optimal view and the dimensions of the indoor unit of the split system, it is necessary to study in detail its structure and principle of operation. This information will help you choose the best effective option, which fits perfectly into the interior of the room and takes up a minimum of free space.
Is it worth disassembling the indoor unit to service the air conditioner
Indoor unit device
The indoor module of the air conditioner belongs to the technical complex structures. It includes a large number of basic elements and a few additional details. At correct assembly this makes it possible to obtain an effective device that will maintain the specified temperature conditions in the room.

How it works and additional features
The split system unit does not differ in the complexity of the action. It can be easily understood not only by a highly qualified specialist, but also by a person who examines it for the first time. The operation of the device is possible thanks to the refrigerant. It is a liquid gas (freon), which helps to cool hot air to the desired temperature.
The device operates according to the following principle:
In addition, the components of the air conditioner, the main module of which is located indoors, may contain several auxiliary electronic devices that facilitate control and add new features. Among them are the following:
- a self-diagnosis sensor that allows you to detect some malfunctions and warn the owner of the device about them;
- control function of the device from a smartphone;
- devices that support automatic operation apparatus in a given mode;
- liquid crystal display, which displays all the information about the operation of the unit.

Varieties of modules
Manufacturers of air conditioners produce a large number of a wide variety of variations of indoor modules. This helps consumers to choose the most convenient option, which is ideal for a particular room.
All modules differ from each other not only in the way of installation, size, but also in the presence or absence of certain characteristics. This helps to choose the optimal dimensions of the indoor unit of the air conditioner, as well as the mounting method.
wall variant
This type of split system module is considered the most common. It gained its popularity due to a large number of advantages compared to other designs. The wall block is installed indoors and serves as a fence warm air, as well as the transfer of chilled. An external module is connected to it with the help of wires and special tubes, which is located on the street.
The wall structure has only one significant disadvantage- complexity installation work. Their implementation requires not only special equipment, but also highly qualified workers. However, this negative side of the wall block is compensated by a sufficient number of advantages. Among them are the following:
- compact size, which allows you to install modules even in the smallest rooms;
- low noise level emitted during operation;
- a large number of various functions, which are typical for almost all device models;
- the ability to rationally fit the unit into the interior of the room.
Cassette type
Home hallmark this type of split system modules is the ability to attach the unit to the ceiling and hide it in suspended structure. This helps not only to save all the free space of the room, but also to perfectly fit the device into the interior.
Internal cassette-type modules are considered the most efficient. They evenly distribute air flows throughout the room and help to create comfortable temperature conditions as quickly as possible.
Other advantages of this design are:
- the ability to control using a special wall or remote control;
- invisibility in the room (visitors will only see decorative panel built-in indoor unit);
- correct distribution of warm air currents;
- high power, which makes it possible to cool the air in large rooms.
Due to the latter advantage, cassette devices are used to maintain the desired temperature in large offices, restaurants, shops and trading floors. These devices are perfect for rooms separated by partitions, where it is not possible to install other types of units.
Despite a large number of positive aspects, cassette modules also have disadvantages. They must be taken into account before buying a device and starting to use it. Otherwise, you may encounter various difficulties that will complicate the installation and operation of the air conditioner. The disadvantages are:
- the need for arrangement false ceiling;
- the complexity of mounting a hidden unit in a pre-installed suspended structure.
Floor and ceiling construction
This is another fairly common version of the device. The indoor unit can be installed horizontally (on the ceiling) or vertically (on a wall close to the floor). This design is used in all cases when there is no false ceiling in the room, and the power wall air conditioner not enough.
The floor-to-ceiling module of the split system has a number of positive characteristics, thanks to which it is very popular among the owners of volumetric commercial premises and offices. The main advantages are:
- high performance indicators;
- the possibility of cooling the air in rooms of complex configuration (elongated, round, curly);
- uniform distribution of air flows over the entire area;
- no direct hit of the cold stream on people.
The floor-to-ceiling design has several disadvantages. Because of them, not every owner of the premises will make a choice in favor of this device. Among the most significant are the following:
- high cost of the module;
- the high cost of installation work;
- large air conditioner.
Disassembly and cleaning of the air conditioner.
Channel products
They are intended only for complex air conditioning of offices, apartments and entire buildings. All indoor units are completely hidden in the attic or behind a false ceiling. Only remains visible ventilation grille and anemostats (devices used to regulate airflow and pressure in complex system).
Channel type design needs equipment additional system air ducts. As a rule, these elements are made of flexible materials and are hidden behind the ceiling. With the help of special tubes, they are connected to an external module, which is located on the street.
The main advantages of channel devices:
- lack of visibility of the internal module and most of the design details;
- the possibility of transferring fresh air through the air duct system into the room;
- the ability to reduce the temperature in several rooms at once.
Ducted air conditioners are very difficult to install so this process can take a long time. In addition, the cost of installation work is quite high. Other disadvantages include uneven cooling various rooms buildings, the difficulty of maintaining the set temperature, as well as the need for space to accommodate all elements and the module.
What to do if the air conditioner drips? First of all, you need to get to the drainage.
column apparatus
Air conditioners of this type are used to maintain the temperature in a room where a fairly powerful flow of cold air is needed (museums, theaters, restaurants). Their indoor unit is the size of a refrigerator and is installed in a place inaccessible to people. The module shutters can move in different planes, which allows you to precisely adjust the direction of air flow.
The main advantage of this model of the device is a large cooling capacity. In addition, the installed equipment is located in a separate room and does not disturb the decoration of the ceilings and walls of the room.
Among the shortcomings are the following:
- large weight of the indoor unit;
- significant dimensions, compared with other models;
- a strong current of cold air generated near the module.
Mobile equipment
This option is used only in cases where it is not possible to install any other type of air conditioner. The mobile device is a block that contains all the components of the design. You need to place it in a room where the desired air temperature will be maintained. The advantages of such a device are ease of installation and the possibility of frequent transportation or movement from one room to another.
Disadvantages of mobile installations:
- big weight;
- poor performance;
- high price;
- inconvenience due to condensate drain;
- the need to bring the duct outside the room;
- high noise level.

Types and types of household air conditioners
Similar climatic devices are installed in large apartments, country houses and small offices. Monoblock models and split systems are divided by the number of blocks. If several indoor devices are connected to the outdoor unit, then these are multi-split systems.
- Split systems are air conditioners consisting of two blocks - external and internal blocks. Internal, as a rule, wall-mounted, mounted indoors. External put outside. A connecting route of freon pipes is laid between the blocks and electrical connections. Household split systems are widely used in apartments, offices, cottages, small houses.
- Multi split systems are household air conditioners that consist of several indoor units and one outdoor unit. Internal are installed in different rooms so that you can set your own temperature and other climate control parameters for each of them. Multi split systems are installed in large apartments or private houses and offices. One outdoor unit installed on the street.
How to choose the best home air conditioner?
Before buying climate equipment, it is important to pay attention to the size of the room, the place where the indoor unit will be located, and what additional functions necessary.
During the operation of a household split system, you can feel bad smell rot along with air currents from the device. It indicates the need for preventive cleaning of the unit. In addition to repulsive amber, clogging of nodes can cause rapid wear of the power unit, increased power consumption and the occurrence of allergic reactions in humans.
This procedure can be entrusted to an employee service center. But if you have been using a split system for a long time, you can handle the work yourself, saving money. It is only necessary to familiarize yourself with the procedure for disassembly and preventive cleaning.
Indoor unit dimensions
Before installing the indoor unit of the air conditioner, you should take an interest in its dimensions. This is especially important when renovating modern technologies quite often provide for the installation of suspended ceiling systems, which can affect the height of the ceiling, as well as the parameters of the described device.
On sale you can find non-standard models that have unique sizes. The length of the block usually varies from 700 to 800 mm. Products up to 900 mm are somewhat less common. Experts recommend taking into account an average length of 770 mm.
As for the height, it is usually equal to 250-290 mm. The average value is 270 mm. Depth is not of great interest to consumers, but it reaches 240 mm. Minimum value equivalent to 170 mm. From this we can conclude that the average dimensions of the indoor unit of the air conditioner are 770 x 270 mm.
Knowing these parameters allows you to determine at what distance from the ceiling and walls to hang equipment. There are a lot of controversies on this issue. In some instructions minimum distance is 50 mm, while in others it reaches 300 mm. Optimal value equal to a figure from 60 to 150 mm.
Specialists usually install air conditioning with a distance of 100 mm. Before installing the indoor unit of the air conditioner, it is important to consider whether there will be curtains in the room. The step between them and the split system is usually 150 mm. You can increase this value up to 250 mm. The average distance from the block to the wall is 400 mm.
Classification of indoor units
In order to carry out disassembly, it is necessary to determine the type of the indoor unit of the air conditioner, which can be represented:
- wall split system;
- channel air conditioner;
- cassette device.
The most common are wall models, which are more affordable and are sometimes also called household. Their installation can be carried out in a room for any purpose, and the power within 7 kW allows you to cool up to 70 m2 of area. Such blocks are usually installed in the upper part of the wall, not far from the window, since the design provides for the presence of an outdoor unit, and the nodes must be interconnected.
Wall-mounted air conditioners are not capable of supplying fresh air to the premises, as this requires a separate ventilation system. If you wondered how to disassemble the indoor unit of the air conditioner, you can read this information below. It is for such a device that the recommendations in the article are given.
Apart from domestic air conditioners, some manufacturers supply semi-industrial devices to the market, the power of which reaches 10 kW. Outwardly, they look like traditional split systems, but in terms of parameters they are semi-industrial equipment.
Ducted air conditioners are installed with suspended ceilings that hide them completely. The distribution of cooled air is ensured by means of heat-insulated air ducts, which are located in the interceiling space. Such structures can cool several rooms at once. The power of the equipment reaches 25 kW, which makes it possible to provide cooling for a cottage or several rooms of an apartment. As a main feature channel systems the possibility of supplying fresh air in the volume that is guaranteed by the functioning of full ventilation.
Cassette air conditioners require a false ceiling during installation. When compared to duct designs, cassettes distribute cooled air through lower part block. It is closed with a decorative grill and usually has the following dimensions: 600 x 600 and 1200 x 600 mm.
Dismantling and cleaning the air conditioner
To clean the indoor unit of the air conditioner, it is necessary to disassemble it. For this, screwdrivers of various configurations and sizes are prepared. You should take care of the presence of a box for collecting fasteners. Requires electrical and functional diagram device. On some models, they are printed on inside top cover.
To clean the internal elements you will need:
- clean rag;
- detergent;
- a vacuum cleaner.
The first step is to de-energize the air conditioner. This is in accordance with electrical safety regulations. Remove the plug from the socket. The top cover of the block is removed. Bolts are unscrewed, which can be two or three. Usually they are closed with decorative caps. The top cover of the indoor unit is removed. If it is covered with a layer of mold and dirt, it should be washed in the bathroom with detergents and brushes.
When disassembling the indoor unit of the air conditioner, you will need to remove the air filters. They are made of plastic and are designed for rough air purification. Sometimes they are fixed on the lid or inside the air conditioner. The filters are washed under an intense stream of water. A brush will help with this.
The airflow guides should also be removed. Blinds are removed from the grooves. To facilitate the process, you need to slightly bend them. These elements direct the flow of cold air into the room and also need enhanced flushing.
Removing the bottom cover
The next step is to remove the bottom cover. Will need to extract drainage tube and power wire. In the process of this, three latches should be pressed and the drain tray together with the outlet hose should be disconnected from the unit.
Removing terminal blocks
The indoor unit of the air conditioner has terminal blocks. They are disconnected during disassembly, and then the electronic control unit and transformer are removed. In order to remove the first one, it is necessary to wring out the side fasteners, and then pull the device towards you. Before this, the ground wires are unscrewed.
Removing the fan motor
The fan motor can now be removed. To do this, the bolts are unscrewed, which are strengthened to the chassis. The evaporator is raised and the engine is pulled out along with the rotary fan. The motor must be separated from the fan, but first you have to warm up the bolt head with a soldering iron. This will unlock the thermal lock on the motor pulley. Once the fan blades can be removed, they must be washed. Assembly is carried out in the reverse order.
Cleaning the outdoor unit
Outdoor and indoor units of air conditioners are equally in need of maintenance. The frequency for the first is twice a year, which is true even with intensive use. A vacuum cleaner is required for this, but the device must be powerful enough to pull dust from external filters and heat exchange radiators.
On your own or with the help of specialists
If the unit is located at an impressive height, then you can unscrew the protective grille and vacuum it, as well as wipe the insides from dust. Otherwise, you can seek help from professionals who will remove the air conditioner using climbing equipment or a tower. Cleaning yourself can be done using compact senders, but the air conditioning system will have to be de-energized and turned on only 30 minutes after the end of the service.
Finally
During the operation of the split system, dust settles on the fan impeller, where a “fur coat” of dirt is formed. This prevents the passage of air flow when blowing the evaporator. The latter freezes over, and the user does not receive normal cold and intense air flow.
Cleaning the fan of the indoor unit of the air conditioner is also required when you see black flakes flying out of the appliance. This suggests that the amount of dirt is so large that it does not hold onto the internal nodes. As a preventive measure, from time to time you can dismantle the fan and wash it. chemicals. But not all models make it easy to extract this part of the system.
