The introduction of new technological solutions in household equipment often runs counter to practical expediency. The example of climate control technology is most illustrative in this sense. So, recently the market has been actively filling up with products intended for indoor use. The features of such systems include the complete elimination of dirty installation operations, which attracts a considerable audience of consumers. But despite all the ease of installation and further maintenance, such models are not able to come close to the performance characteristics provided by external unit air conditioner as part of a split system. Another thing is that owners of outdoor installations also have to deal with troublesome tasks, but of a different kind.
What is an external unit?
The outer segment, which is part of the split system complex, includes a condenser, valve decoupling, pipes, filter driers and a fan. Depending on the modification and design, the internal “filling” may change, but a traditional air conditioner kit with a remote unit has exactly this set of elements. By the way, the most noticeable differences are observed in the so-called winter systems, which provide for the presence of special controllers for controlling the fan. Modern air conditioners also use multifunctional power switching relays. Such devices are designed for non-standard operation of the compressor under conditions of high or low temperatures. Unlike the internal segment, outdoor unit does not have electronic modules - its operation is completely subordinated to the mechanical function.
Block Dimensions
The outdoor unit is available in the market in different configurations and shapes. And although manufacturers strive to unify model lines in order to simplify segmentation, the choice of standard sizes is still quite wide. If we talk about average parameters, it is 770 mm wide, 450 mm high and 245 mm thick. In this case, the radius of the fan varies on average from 200 to 250 mm. Of course, there are also units whose dimensions deviate from these indicators. Thus, the Mitsubishi line includes an external air conditioner unit of almost square shape, which is 880 mm wide and 840 mm high. As for the parameters of the internal segment, they are not so impressive. Usually these are long narrow modules of medium size - 700 x 200 x 200 mm.
Selecting a location for installing the unit
Usually, when choosing the optimal point for installing air conditioners outside, users are faced with the problem of combining ease of use and protection of the module. For example, the location of the block at height is the best option from the point of view of its safety, but in this case, access to the air conditioner for maintenance purposes becomes more difficult. A good solution would be to place the module on the wall near a window opening or loggia. In this case, other nuances must be taken into account, including the absence of direct rays of the sun and permission for installation from neighbors, since a noisy unit can cause inconvenience to people living on the same level of the building.
In addition, it produces condensation, which will flow down in drops. Accordingly, you will have to negotiate with neighbors on the lower floors. If the installation location of the unit is successfully agreed upon with other residents, you can begin direct installation operations. By the way, another condition for installing an outdoor unit is the possibility of laying communications in the wall.
Installation of the external air conditioner unit
When installing air conditioners, special installation kits are used, which include pipes with flex, brackets with sets of fixing hardware, drainage communications, etc. The physical installation of the segment is carried out using load-bearing components, which are embedded in the walls using anchor elements. At the same stage, brackets are used, the power potential of which is oriented towards the mass of a particular module. Also, the installation of an external air conditioner unit provides for its communication connection with the internal segment. To do this, a hole is made in the wall required diameter, which will allow you to organize, in addition to the main wiring, also the laying vacuum pump and manifold. At the final stage, communications are directly connected between the two blocks.
Features of installing the indoor unit
When installing the evaporative unit, that is, the internal module of the air conditioning system, it is especially important to maintain the correct position of the unit. Typically this unit is mounted directly under ceiling surface with a slight indentation. Mechanical fixation is also carried out using suitable brackets. True, in in this case The weight of the equipment is not so great, which simplifies the work process. After marking, the master installs anchor elements and, if necessary, attaches supporting profiles. Next, the indoor unit of the air conditioner is installed with strict adherence to the horizontal position. Also, according to the instructions, some models of such segments must have slight slope towards the drainage passage.
Maintenance and care
Under standard operating conditions, the air conditioner must be serviced every six months. Most of the work is done with the external unit, which is most susceptible to contamination. Specialists usually check the condition of filters, refrigerant levels, operating pressure module traces, etc. The most difficult operation is replacement working fluid. The refrigerant is a chemically unsafe substance, so it is better to trust its refilling experienced craftsmen. But caring for the remaining components is quite accessible to ordinary users. For example, the answer to the question of how to clean the external unit of an air conditioner is quite simple. First of all, it should be disassembled, after which, using a rag or vacuum cleaner, remove internal surfaces module from dust and dirt deposits. In the process of such maintenance, external filters and heat exchange radiators are cleaned, which extends the service life of the air conditioner.
External unit in multi-systems
The concept of the technical implementation of a split system provides for the possibility of using several indoor modules in one complex, which are serviced by one outdoor unit. Unlike standard configurations, the external module of such a system has engineering differences. For integration into a multi-system, it is equipped with an additional thermostat, which allows you to more effectively control the fan and compressor settings. In turn, the indoor unit of the air conditioner acts as a source of information signals that determine the control of the outdoor module. That is, the user using remote control accesses the panel indoor unit, and he, in turn, regulates the bypass communications system on the freon line via a digital channel.
Question of price
In modern modifications, split-system type air conditioners are not cheap, which is largely due to the complexity of the design. Even in the entry-level segment, the cost of an air conditioner with a remote unit is rarely less than 20 thousand rubles. Of course, you can also find options for 15 thousand rubles. from little-known brands, but their quality raises doubts both among specialists and among users themselves, who often complain about problems.
Decent quality models are offered by Fujitsu, Daikin, Mitsubishi, etc. The average cost of an air conditioner from the range of these companies varies in the range of 30-40 thousand rubles. At the same time, the most technologically advanced and productive kits can be valued at 70-80 thousand rubles.
Conclusion
The use of air conditioners with a design that requires the installation of a remote unit causes many problems during installation and further maintenance. And this does not take into account the difficulties in transporting equipment. These factors allow us to speak of such units as obsolete. Especially against the backdrop of the proliferation of mobile devices of modest size. However, the external air conditioner unit remains relevant in the market. This explains his high performance, functionality and safety during operation, since the main operating units are located outside the living space. And if for household use you can find a low-power replacement for a split system in the form of a monoblock, then in the context of maintenance office premises, public buildings and institutions, multifunctional complexes still have no equal.

Greetings to all visitors to the Air Conditioner website! There are situations when you need to know the dimensions of the outdoor unit of the air conditioner. This question arises when the block is planned to be placed in limited space. Sometimes these dimensions play a decisive role in the choice.
It happens that in the allocated space there is not enough space for free arrangement of blocks. Then you have to choose a different installation location or, for example, replace two external units with one (this will already be a multi-split system).
On the Internet by a certain model air conditioner you will find the characteristics where indicated dimensions blocks. But if you have not yet decided on a specific model, then you will need to know at least the approximate dimensions. Today we will try to determine the average dimensions of the outdoor unit, focusing on the characteristics household wall split systems.
What determine the dimensions of the outdoor unit?
The dimensions of the block body, of course, are determined by the dimensions of the component parts. The largest parts of the external unit are the capacitor (radiator) and. The size of the blocks depends on their performance. The more powerful the air conditioner, the greater the “capabilities” and dimensions of its main components.
It's no secret that air conditioners come in different cooling capacities. In most cases, there is a direct relationship between the cooling capacity and the dimensions of the unit (especially one line). But when comparing different brands or models, you may get different numbers!
Of course, the more powerful the air conditioner, the larger its parts, the larger the dimensions of the units. But now “splits” with inflated characteristics are appearing. To reduce the price, they are assembled from budget components, which hardly provide the declared cooling capacity. This is also why different brands may have significantly different dimensions for the same power.
Dimensions of the external unit of the air conditioner
If we consider the productivity of a “split” up to 2.7 kW, then the height of the external unit will be approximately 42-60 cm. On average, this figure will be about 50 cm. You may need the height of the bracket “foot” - usually 7 cm.
The width (without taps “protruding” beyond the body) is usually 66-80 cm. Taking into account my experience, I suggest taking the distance of 70 cm. The depth of small air conditioners is usually 23-30 cm.
Thus, we received the approximate dimensions of the external unit:
- height 50 cm;
- width 70 cm (note that the service taps “protrude” beyond the body by an additional 6 cm);
- depth 27 cm.
I will supplement these figures with the distance between the external block and the wall of the building - on average 15 cm. Taking into account this indentation, the external block will be located at a distance of 42 cm from the wall (cladding) of the house.
For clarity, we present the average dimensions of external units for household air conditioners in the form of a table.
Focusing on these figures, do not forget about the variety of climate control equipment. If you have limited space for the outdoor unit, then before purchasing the device, still check the dimensions for a specific air conditioner model.

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 room and sends it back already cooled.
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 units are connected to each other by electrical wiring and a 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 that are 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 remote control.
The external unit is simpler, and instead of an evaporator, the device contains a condenser - a unit responsible for the phase transition of freon from gaseous state into liquid.
Modern split systems include an outdoor unit and indoor air conditioner unit. When installing a multi-split system air conditioner of free configuration with one outdoor and several indoor units, it is possible to choose the internal units of the air conditioner of duct, cassette, floor, ceiling types, which allows you to ideally fit the indoor air conditioner unit into the design of any, even the most sophisticated, interior. Let's take a closer look device of the internal unit of the air conditioner and their varieties.
Air conditioner indoor unit. Device
Air conditioner indoor unit wall type comprises:
1. Front panel- represents plastic grill, through which air enters the unit. The panel can be easily removed for servicing the air conditioner (cleaning filters, etc.)
2. Coarse filter- represents plastic mesh and is designed to retain coarse dust, animal hair, etc. For normal operation The air conditioner filter must be cleaned at least twice a month. The latest air conditioners from some manufacturers use an automatic filter cleaning system.
3. Fine filter- comes in different types: carbon (removes unpleasant odors), electrostatic (retains fine dust), etc. The presence or absence of fine filters does not have any effect on the operation of the air conditioner, but does affect the purity of the air inhaled by a person in the room. Air conditioners with serious air purification systems are more expensive. Premium segment air conditioners are equipped with such filters (for example, Mitsubishi Electric MSZ-FD25VA and MSZ-FD35VA air conditioners).
4. Fan - has 3 - 4 rotation speeds.
5. Evaporator - a radiator in which cold freon is heated and evaporated. The air blown through the radiator is cooled accordingly.
6. Horizontal blinds - regulate the direction of the air flow vertically. These blinds are electrically driven and their position can be adjusted using a remote control. In addition, the blinds can automatically perform oscillatory movements to evenly distribute air flow throughout the room.
7. Display panel- on the front panel of the indoor unit of the air conditioner there are indicators (light emitting diodes) or LED displays showing the operating mode of the air conditioner, the selected temperature and other necessary information. If the air conditioner has a self-diagnosis mode, the display displays an error code possible malfunction. It is very comfortable.
8. Vertical blinds- serve to adjust the direction of the air flow horizontally. Usually in household air conditioners The position of the blinds can only be adjusted manually. Possibility of automatic adjustment vertical blinds using a remote control is present only in some models of the "Premium" segment.
9. Condensate tray(not shown in the figure) - located under the evaporator and serves to collect condensate (water formed on the surface of the cold evaporator). From the pan, water is discharged outside through a drainage hose.
10. Control board(not shown in the figure) - usually located with right side indoor unit. This board contains an electronics unit with a central microprocessor.
11. Union connections(not shown in the figure) - located in the lower rear part of the indoor unit. They are connected to copper tubes connecting the outdoor and indoor units.
Wall type indoor unit
The appearance of the indoor unit of the air conditioner, or in other words its type, may be different. The most popular are wall-mounted split systems, which include wall-mounted indoor unit. This is the most cost-effective multi system layout, because... Wall-mounted indoor units are cheaper than other types of indoor units.
Duct type indoor unit
These indoor units are used where hidden installation of an air conditioner is necessary and there is no desire to place anything on the walls or ceiling. Channel-type indoor units are usually located in dressing rooms or hidden behind suspended ceiling in a specially designated place. These units require a service hatch for periodic service. Supply of cold or warm air into the room is carried out using air ducts.
Cassette indoor unit
This type of indoor units is used when it is not possible to place wall units. The cassette indoor unit can be single-flow or 4-flow. Single-flow cassette units are usually used for air conditioning in apartments and country houses. For large, voluminous office premises, shops, etc., four-flow cassette indoor units are used.
Air conditioner dimensions of the indoor unit
As you already know, a split system can include Various types blocks, the dimensions of the indoor unit differ accordingly. The dimensions of the indoor unit of a wall-mounted air conditioner vary depending on the manufacturer and the power of the air conditioner. The higher the power of the wall split system, the more indoor unit dimensions. On average, the width of an indoor unit air conditioner ranges from 780 to 1100 mm.
Offered by some companies, such as Fujitsu. The Fujitsu Standart series air conditioner has a small internal unit with dimensions of 260x790x198mm. In the line of wall Daikin air conditioners presented the latest split system Daikin Emura FTXG25J, which has thinnest indoor unit size- block thickness is only 156 mm!
LG offers original wall mounted indoor units of air conditioners LG ART COOL GALLERY square shape. These indoor units provide a unique ability to replace images. You can install in LG air conditioner indoor unit any picture or photograph.
Air conditioners with 2 indoor units are most often used to condition several adjacent rooms. This system uses one outdoor and two indoor units. Indoor units can be wall-mounted, cassette or duct-mounted. Systems with two indoor units are called multi split systems.
