Split systems firmly occupy a leading position among domestic and semi-industrial climate systems. The optimal price-quality ratio, choice of design and wide functionality ensure a steady demand for split-system air conditioners 24. At the same time, most owners have little understanding of the principle of operation of a split-system air conditioner and its device.
Split system air conditioner device
All split-system air conditioners are arranged in the same way. The outdoor unit is installed on the street (building wall, facade, roof). It contains the compressor and condenser - the most important components of the cooling system, as well as the fan and some other components. The electronic inverter control module is also located in the external unit. If the air conditioner is equipped with a "winter kit", the control board is built in here as well.
According to the design of split-clock air conditioners, all control boards are located in the indoor unit.
The indoor unit is wall-mounted, ceiling-mounted, floor-mounted. The electronic control board is located here, which controls many functions:
- reads signals from the remote control;
- controls the air temperature;
- regulates the cycle of switching on and off cycle air conditioners;
- regulates the operation of the evaporator fan;
- changes the direction of the blinds;
- carries out time control (timer).
This is an important element of the split-system air conditioner device.
The principle of operation of a split air conditioner
The principle of operation of split air conditioners is based on the ability of the heat carrier to radiate and take heat during evaporation or condensation.
Split air conditioner device is based on the following working units:
- Compressor... Provides pressure change;
- Evaporator... Extracts heat from indoor air;
- Capacitor... Transfers heat to the atmosphere;
- Refrigerant... Heat transporting substance.
According to the principle of operation of the split-system air conditioner, the coolant enters the compressor from the evaporator in the form of steam, here it is compressed and fed to the condenser. Now the coolant gives off heat to the street, its temperature decreases, it turns into a liquid. After passing through the expansion valve, the coolant is transferred to the evaporator, here the pressure drops and the refrigerant evaporates. The principle of operation of the split air conditioner is based on cyclicality.
