Split systems are firmly in the lead among domestic and semi-industrial climate systems. The best price-quality ratio, design choice and wide functionality ensure steady demand for split-system air conditioners 24. However, most owners have little idea of the principle of operation of the split-system air conditioner and its device.
Split system air conditioner
Split system 24 air conditioners consist of two modules: external and internal. Between the two modules are stretched electrical wires and refrigerant tubes.
All split-system air conditioners are designed identically. The outdoor unit is installed on the street (building wall, facade, roof). It contains a compressor and a condenser - the most important components of the cooling system, as well as a 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 integrated here.
According to the arrangement of split-clock system air conditioners, all control boards are located in the indoor unit.
The indoor unit is hung on the wall, the ceiling is installed on the floor indoors. Here is an electronic control board that controls many functions:
- reads signals from the remote control;
- controls air temperature;
- regulates the cycle of turning on and off clock air conditioners;
- regulates the operation of the evaporator fan;
- changes the direction of the blinds;
- carries out temporary control (timer).
This is an important element of an air conditioner split system.
The principle of operation of split air conditioner
The principle of operation of split air conditioners is based on the ability of the coolant to radiate and collect heat during evaporation or condensation.
The split air conditioner device is based on the following operating units:
- Compressor. Provides a change in pressure;
- Evaporator. Removes heat from indoor air;
- Capacitor. It transfers heat to the atmosphere;
- Refrigerant. Heat transporting substance.
According to the principle of operation of the air conditioner of the split system, the coolant in the form of steam enters the compressor from the evaporator, here it is compressed and fed to the condenser. Now the coolant gives 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 an air conditioner split is based on cyclicity.
