Quite often, the population is interested in how to find out if an apartment has been privatized or ...
Optimal temperature indoors allow you to provide split systems with a "remote" outdoor unit. For creating comfortable conditions in all areas of the apartment, multi-split systems for 3 rooms are suitable.
Device
Split system — complex view air conditioner, which includes two blocks: external (compressor-condensate unit) and internal (evaporative). outdoor unit mounted outside the building on the wall. The indoor unit (air conditioner) is mounted indoors.
A compressor and condensate unit (CCU) is an element of climatic equipment that performs the function of refrigerant movement in a closed cycle.
KKB consists of several parts:
- compressor - compresses the working substance;
- condenser (heat exchanger) - cools;
- choke (expansion coil) - expands.
KKB includes additional working elements: an engine for a compressor, capillary tubes, a fan. Throttle with drying filter and solenoid valve is combined into a KKB harness.
The evaporator unit is a part of the climatic equipment that performs the function of transferring the refrigerant from a liquid to a gaseous state with heat absorption. The evaporator consists of:
- cooling coil;
- long fan;
- air filters.
The indoor unit can be equipped with additional functionality: remote control, air purification filters, timer, smooth temperature control modes.
The outdoor unit is connected to the indoor heat-insulating and drainage main.
Power is supplied through special electrical connections.
A refrigerant is a working substance (heat carrier) that, under the influence of pressure, passes into various states and changes the temperature of the surrounding air. During the transition from a liquid state to another, as a result of compression and an increase in pressure, energy is absorbed. The return to the liquid state, with the expansion and decrease in pressure, leads to the release of energy to the outside.
Types of split systems:
- Wall mounted;
- Floor and ceiling;
- Channel;
- Column type;
- Cassette type;
- Central air conditioners;
- Rooftop.
In KKB there is a container with a working substance. refrigerant circulating through copper pipes, cools the air that is supplied to the indoor unit from the street. The room temperature drops.
Modern split systems provide for operation in two modes: cooling and heating.
Switching the mode to increase the temperature in the room leads to a reversal of the use of the refrigerant - it begins to evaporate in the outdoor unit, and condenses in the indoor unit.
Split system operation:
- The compressor compresses the working substance in the gaseous state.
- The compressed refrigerant enters the condenser, where heat energy is released during the transition to a liquid state.
- Having lost part of the heat, the working substance enters the line. The refrigerant maintains an elevated pressure.
- The working substance enters the throttle and expands sharply, which leads to cooling.
- The liquid gas enters the evaporator.
- In the evaporator, the refrigerant is blown with warm supply air from the room using a fan. Heating occurs (the evaporator plays the role of a heat exchanger) of the working fluid, which boils and passes into a gaseous state.
- When evaporating, the refrigerant gives off cold to the evaporator and takes heat.
- The gas goes back to the compressor.
- The process continues in a circular fashion.
When changing the mode to heating, the process occurs in the reverse order. The evaporator takes over the function of the KKB and heats the air due to the transition of the refrigerant from a gaseous to a liquid state. KKB turns into an evaporator.
Advantages
A multi split system differs from conventional equipment of this type in that the device in it allows you to connect several internal elements to one external unit. This configuration looks optimal for installation in three rooms at once.
Advantages:
- Wide functional coverage. Different models make it possible to connect from 2 to 9 units with a power of each up to 9 kW. The possibility of a cooling system for rooms with a total area of up to 100 square meters. m.
- Variety of technical capabilities. Allows you to select indoor units with the required power parameters for each room.
- Aesthetics and space saving. Mounting only one outdoor unit on the wall of the building. Such a system does not spoil the facade of the building with numerous communication elements.
- Ease of management and maintenance from one point. Regulation of the system operation in all places of installation.
- Profitability. Consumes less resources.
- Acceptable price. Buying one multi split system is cheaper than buying several conventional models. Installation is also easier and cheaper.
Many experts call the key disadvantage of all multi-split systems that all blocks of such equipment can only work in one direction: for heating or for cooling. But this minus is doubtful, because the control system allows you to adjust the settings of each indoor unit separately, that is, in each room you can adjust the optimal temperature.
The only significant disadvantage of multi split systems is that the failure of the external unit will lead to the cessation of the entire system.
The average life of a split system is more than ten years. At correct installation, competent operation and timely maintenance of the equipment will last fifteen to twenty years.
Models
Present on the market a large number of split systems of various manufacturers. You can choose models from global corporations, or you can purchase a sample from a company that specializes only in the production of air conditioners and other similar equipment.
Leading brands offering quality multi-split systems include:
- Daikin.
- Mitsubishi and Mitsubishi Electric.
- Pioneer.
- Hisense.
- Toshiba.
- hitachi.
Decent and high-quality models are offered by all leading manufacturers. To choose the optimal and efficient air conditioner for 3 rooms, you need to pay attention to the following parameters:
- system type;
- the number of connected blocks;
- power;
- the volume of rooms that the device is able to cover;
- operating modes;
- the presence of an inverter;
- noise level of external and internal blocks;
- availability of additional functions;
- set of means of fixation;
- filtering equipment;
- the presence of a "winter kit".
It is important not to chase the price when installing. Installation of equipment is a complex and expensive task. Dismantling, in the event of a breakdown or replacement, can cost 50% of the cost of the equipment. It is better to overpay for quality at the stage of initial purchase and installation than to pay later for rework and replacement.
In the northern latitudes, it is worth purchasing systems that provide for a "winter kit".
This equipment allows you to protect the outdoor unit from freezing at low temperatures. When installing, use original parts, especially when installing an outdoor unit.
Installation
Installation of air conditioning systems must be trusted experienced craftsmen, since the efficiency, correctness and durability of the equipment operation depend on the literacy of the installation. The best solution- ordering the installation in the company where the equipment is purchased. So, the performers will be interested in a competent installation, for maintenance and repair, if the work is done well, they will turn to them. In the event of a breakdown, employees will not disappear, because not people are responsible for the result, but the company with which the contract for the purchase and installation is drawn up. It is best to mount the system at the construction stage if it is a private house, or during the period of repair in an apartment building.
The sequence of actions when installing a split system for 3 rooms:
- Planning of system placement: location of KKB on the facade of the building, location of indoor units in the premises, passage of communication lines.
- When planning and agreeing, the distance between the blocks, the efficiency of the air conditioner in a particular place, the presence of other engineering networks in the building (heating pipes, water supply, electrical networks). It is important to consider the location in the rooms of furniture, household appliances.
- Marking the locations of blocks and connection lines. Checking the completeness of the equipment.
- Drilling of openings and chasing of channels on a marking.
- Laying a heat-insulating line and wires connecting the blocks.
- Installation of brackets on the facade of the building. Fixing to the brackets of the outdoor unit.
- Installation of indoor units in rooms.
- System operation testing.
- Vacuumization of the route to protect against moisture and foreign objects.
- Works on sealing holes and sealing channels in the walls.
After installing a split system for three rooms, it is important not to forget about the mandatory system maintenance.
Air conditioning units require annual cleaning, filter replacement and refrigerant renewal.
Violation of the maintenance rules will significantly reduce the efficiency of the equipment, reduce the service life and increase the risk of breakdown.
Multi split systems for three rooms gained wide popularity among owners large apartments and private cottages. The advantage of choosing such a split system is in rational use space and energy savings. When installing a multi-split system, only one outdoor unit is installed, to which all indoor units are connected. At the same time, any variability of configuration is allowed - the buyer can choose indoor units of various capacities and even types (depending on the area and design features of the premises). So, wall, ceiling, floor-ceiling and other indoor units can be connected to the outdoor unit.
The choice of outdoor unit is determined by the required total capacity of all indoor units. Functionally, the indoor units of a multi-split system are no different from standard air conditioners, with the exception of more convenient control and energy efficiency. The energy consumption of the equipment depends on the energy efficiency class. The most economical and reliable models are split systems with an inverter compressor type.
Multi split system for 3 rooms has such advantages as:

Models are presented in a wide price range, so you can choose a split system based on your budget, stated requirements, design features and floor space.
How does a multi split system for 3 rooms work? On the technical side of the issue, everything is implemented quite simply. The internal elements included in the kit are installed where it is required by the owner of the premises, while a single external unit is mounted on the outside of the building on:
- facade.
- roof.
- Balcony.
Or at any other suitable point where there is an inflow fresh air. All these functional elements are combined into a single network using highways into which an inert gas (usually freon) is pumped. However, despite such unity, when a multi-split system is installed, 3 units are able to support various temperature conditions, independently of each other. This makes it possible to provide optimal parameters microclimate individually for each room.
It should be noted that not a single multi-split system for 3 rooms, which you can buy from us, can simultaneously function in the modes of air conditioning and heating of air masses. This is due design features such air coolers presented to your attention in a wide range.
When is it worth buying a multi-split for 3 rooms
Despite the advantages of such technical solution, the purchase of equipment is not always justified. Although the price for equipment such as a multi-split system for 3 rooms is lower than for separate air conditioners, the difference will be offset by the cost of installation.
Therefore, such devices should be chosen in cases where many bulky external units cannot be mounted on a building. That's why the best option this technique will become:
- Buildings of historical and cultural value.
- Buildings, the facade of which overlooks busy highways.
- Private houses and cottages.

Multi-split systems for 3 rooms It consists of three indoor units and one outdoor unit. Split systems are selected depending on the area of the room. For example, an indoor unit with a power of 2.0 kW to 2.5 kW is suitable for 20 m2, as a rule, these are the 7th and 9th models, if a room of 30-35 m2 is an indoor unit with a power of 3.5 kW. The length of the route along which freon circulates depends on the distance between the indoor units and the outdoor unit. The longer the route, the more expensive the installation. The power of the outdoor unit is selected by the sum of the power of the three indoor units. Manufacturer of multi-split systems for 3 rooms must be reliable and known, because if the outdoor unit fails, the whole system does not work. And what else you need to know, such systems do not automatically switch from cold to warm, you first need to switch to the desired mode on one of the remotes. Today, such air conditioners are produced by inverter - they save electricity compared to conventional ones up to 30%.
