Installation dimensions of the air conditioner. Features of internal units of split systems, their sizes and fastenings

During operation of a household split system, you may feel bad smell rotted along with air flows from the device. It indicates the need for preventative cleaning of the unit. In addition to the repulsive odor, clogged nodes can cause rapid wear of the power unit, increased energy consumption and allergic reactions in humans.

You can entrust this procedure to an employee service center. But if you have been using a split system for quite some time, you can handle the work yourself, saving money. You just need to familiarize yourself with the disassembly procedure and preventive cleaning.

Indoor unit dimensions

Before installing the indoor unit of the air conditioner, you should inquire about its dimensions. This is especially important during repairs, because modern technologies quite often involve the installation of suspended ceiling systems, which can affect the height of the ceiling, as well as the parameters of the device being described.

On sale you can find non-standard models that have unique sizes. The block length usually varies from 700 to 800 mm. Products up to 900 mm are somewhat less common. Experts recommend taking into account average length at 770 mm.

As for the height, it is usually 250-290 mm. The average value is 270 mm. The depth is not of much interest to consumers, but it reaches 240 mm. The minimum value is equivalent to 170 mm. From this we can conclude that the average size indoor unit 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 contradictions on this issue. Some instructions set the minimum distance to 50mm, while others go as high as 300mm. Optimal value equal to the figure from 60 to 150 mm.

Experts usually install an air conditioner at a distance of 100 mm. Before installing the indoor air conditioner unit, 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. This value can be increased to 250 mm. The average distance from the block to the wall is 400 mm.

Classification of indoor units

In order to disassemble, it is necessary to determine the type of indoor unit of the air conditioner, which can be represented by:

wall split system;
duct air conditioner;
cassette device.

The most common are wall-mounted models, which are more affordable and are sometimes also called household models. Their installation can be carried out in a room for any purpose, and the power within 7 kW allows cooling up to 70 m 2 of area. Such blocks are usually installed at the top of the wall, near 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, since this requires a separate ventilation system. If you are wondering how to disassemble the indoor unit of an air conditioner, you can find this information below. It is for such a device that recommendations are given in the article.

In addition to household air conditioners, some manufacturers supply the market with semi-industrial appliances whose power reaches 10 kW. Outwardly, they resemble traditional split systems, but in terms of parameters they are semi-industrial equipment.

Duct air conditioners are installed with suspended ceilings that hide them completely. Distribution of cooled air is ensured using thermally insulated air ducts, which are located in the inter-ceiling 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 in an apartment. The main feature of channel systems is the ability to supply fresh air to the extent guaranteed by the functioning of full ventilation.

Cassette air conditioners require a suspended ceiling during installation. When compared to ducted designs, cassette designs distribute cooled air through the bottom of the unit. It's closing decorative grille and usually has the following dimensions: 600 x 600 and 1200 x 600 mm.

Disassembling and cleaning the air conditioner

To clean the indoor unit of the air conditioner, it is necessary to disassemble it. For this purpose, screwdrivers of different configurations and sizes are prepared. Make sure you have a box for collecting fasteners. You will need an electrical and functional diagram of the device. In some models they are applied to inner side top cover.

For the cleaning internal elements you will need:

clean rags;
detergent;
vacuum cleaner.

The first step is to turn off the power to the air conditioner. This complies with electrical safety regulations. The plug must be removed from the socket. The top cover of the unit is removed. The bolts are unscrewed, of which there may be two or three. They usually close decorative plugs. 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 air flow guides should also be removed. The blinds are removed from the grooves. To make the process easier, you need to bend them slightly. These elements direct the flow of cold air into the room and also require intensive washing.

Removing the bottom cover

The next step is to detach the bottom cover. Will need to be removed drainage tube and power cord. During this process, you should release the three latches and disconnect the drain pan along with the outlet hose from the block.

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, you need to press out the side fastenings, and then pull the device towards you. Before this, the grounding wires are unscrewed.

Removing the fan motor

Now you can remove the fan motor. To do this, the bolts that are secured to the chassis are unscrewed. The evaporator is lifted and the motor is removed out along with the rotary fan. The motor must be separated from the fan, but first you will 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 need to be washed. Assembly is carried out in reverse order.

Cleaning the outdoor unit

External and internal air conditioner units require equal maintenance. The frequency for the first is twice a year, which is true even with intensive use. A vacuum cleaner must be used for this, but the device must be powerful enough to remove 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 the help of professionals who will remove the air conditioner using climbing equipment or a tower. You can clean it yourself 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 operation of the split system, dust settles on the fan impeller, where a “coat” of dirt forms. This prevents air from flowing through 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 device. This indicates that the amount of dirt is so large that it is not retained on the internal components. As a preventive measure, from time to time you can dismantle the fan and wash it chemicals. But not all models allow you to easily remove this part of the system.

Often, during renovations, many people think about installing a split system and plan the design of rooms to fit the size of the air conditioner. Indoor unit of this device it is necessary to place it in such a way that it is not only correctly positioned, but also looks most harmonious in the intended interior.

The purchase and selection of the air conditioner itself is often planned closer to the end of the repair, and the “power” needs to be supplied now. So, this article was written for such cases. In it we will look in detail at what distances need to be taken into account for subsequent installation, and we will identify the most universal sizes of indoor units (wall-mounted household appliances).

First, we would like to immediately warn you that there are “non-standard” models of air conditioners that may have unique sizes and characteristics. And therefore this article should not be taken as 100% universal.

Air conditioner size. Split system indoor unit

More often living rooms have a small area (up to 25 sq. m.) For such rooms, air conditioners up to 2.7 kW are suitable (not to be confused with power consumption) - they are usually called "sevens" or "nines". As a rule, “sevens” and “nines” (of the same model) have the same overall dimensions, as well as the same tube diameter. Therefore, further we will take into account the same dimensions and characteristics of the considered standard sizes.

Overall dimensions of the indoor unit, which interest us primarily

block length. The most standard length of internal blocks is 700-800 mm. Slightly less common are up to 900 mm. By personal experience It is best to take into account the average length of 770 mm.
block height. Most often these dimensions lie in the range of 250-290 mm. For planning, we will take into account 270 mm.

We are not very interested in depth (170-240 mm). Thus, we have identified the average size of the indoor unit 770 x 270 mm.

Distances from walls and ceiling

Air conditioners “on/off”. We route the cable so that it is subsequently located under the indoor unit ( 300 mm to the left. and below by 100 mm. from the center of the block).
Most

Air conditioning has long become a common household appliance. Of the variety of devices for air cooling, the most popular are split systems, consisting of two unit blocks, one of which is installed outside the room, and the other is located inside. The indoor unit of an air conditioner is a complex device that takes warm air from the premises and sends it back already chilled.

Any air conditioner functions due to the properties of liquids to release thermal energy when releasing liquid and absorbing heat when it evaporates.

The indoor unit is always placed indoors (usually mounted on the wall or ceiling), and the outdoor unit is taken outside. Both blocks are connected to each other by electrical wiring and copper pipeline, through which freon continuously circulates during operation.

Regardless of the design and dimensions, the indoor unit of a split system must have the following components in its design:

Compressor. Responsible for compressing the refrigerant and circulating it through a closed circuit.
Evaporator (heat exchanger). In this radiator, freon is converted from liquid to gas.
Fan. Forces air flow to the evaporator.
Thermostatic valve. Helps reduce refrigerant pressure before the evaporator. As a rule, it is a thin, curved spiral copper tube.
Set of filters. They retain dust and larger fractions of debris inevitably contained in room air.
Air distribution system.
Blinds that control the direction of air flow.
Temperature sensors.
LED indicators.
Information table.

Indoor unit design

Note! Since the internal unit of a split system is often located at an unattainable height, the device always includes a remote control.

The external unit is simpler in design, and instead of an evaporator, the device contains a condenser - a unit responsible for the phase transition of freon from a gaseous to a liquid state.

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 monoblock window models and multi-split systems.

All modern systems conditioners of this brand are different:

multifunctionality;
energy efficiency;
low noise level;
stylish design;
effective system air filtration.

The multi-stage cleaning system not only cleans the air flow of contaminants, but also disinfects it, killing bacteria and microorganisms.

Compact windows

The smallest ducts have a block height of 199 mm. These are so-called low-profile duct-type blocks, which are produced for operation in powerful multi-zone systems.

Ordinary duct air conditioner, designed to work in a room of 40 square meters. m, like the ADH1800E model, it has the corresponding power (5 kW) dimensions 1340x260x600 mm.
