Function:

The air conditioning compressor is one of the core components of the air conditioning system, and its main role is to achieve the cooling or heating cycle through the compression of refrigerant, so as to achieve the purpose of regulating the indoor temperature and humidity. The following is the specific role of the air conditioning compressor:
1. Compression of refrigerant
The main function of the air conditioning compressor is to compress the low-temperature, low-pressure refrigerant gas into a high-temperature, high-pressure gas. This process is a key step in the refrigeration cycle, providing the impetus for the phase change and heat transfer of the refrigerant. Principle: The compressor compresses the refrigerant gas by means of a piston, a scroll and a scroll.
2. Promote the refrigerant cycle
The compressor is the power source of the refrigerant cycle, which makes the refrigerant circulate in the air-conditioning system by continuously compressing and discharging the refrigerant.
3. Realisation of cooling and heating functions
Air conditioning compressor through the refrigerant cycle to achieve cooling and heating functions, the specific process is as follows:
- Refrigeration mode:

- Compression: the compressor will be low-temperature, low-pressure refrigerant gas compressed into a high-temperature, high-pressure gas.

- Condensation: the high temperature and high pressure refrigerant gas in the condenser to release heat and liquefaction, the heat will be emitted to the outdoors.

- Expansion: the liquid refrigerant is throttled down through the expansion valve or capillary tube and becomes a low-temperature, low-pressure liquid.

- Evaporation: The low-temperature, low-pressure refrigerant liquid absorbs heat from the indoor air and vaporises in the evaporator, thus lowering the indoor temperature.
4. Adjustment of the operating state of the air-conditioning system
The operating state of the air-conditioning compressor (such as speed, power, etc.) can be adjusted through the control system to adapt to different cooling or heating needs.
5. Protection of the air-conditioning system
Compressor also through the built-in protection devices (such as overload protector, pressure switch, etc.) to protect the air conditioning system from damage.
- Overload protection: When the compressor load is too large or the current is too high, the overload protector will automatically cut off the power supply to prevent the compressor from overheating and damage.
- High and low pressure protection: through the pressure switch to monitor the pressure in the system, when the pressure is abnormal (such as high pressure is too high or low pressure is too low), the protection device will cut off the power supply of the compressor to prevent damage to the system.
