Air conditioning accessories include circuit control boards, wire controllers, manifolds, refrigerants, electronic expansion valves, motors, compressors, liquid mirrors, and ball valves.

1. When the refrigerant passes through the evaporator, it exchanges heat with the outside high temperature air, so that the low temperature and low pressure liquid absorbs the outside heat and evaporates, and the refrigerant becomes a low temperature and low pressure gas; With heat exchange, the heat is sucked away, so the hot air becomes cold air.

2. The low-temperature and low-pressure gaseous refrigerant passes through the compressor, and the compressor compresses the gaseous refrigerant, so that the refrigerant becomes a high-temperature and high-pressure gas.

3. The high-temperature and high-pressure gaseous refrigerant passes through the condenser. At this time, the temperature of the refrigerant is higher than the outdoor temperature. Therefore, the condenser exchanges heat with the air with a lower temperature outside the refrigerant. At this time, the air absorbs the refrigerant. temperature. As a result, the cooling of the refrigerant becomes a liquid at high pressure and normal temperature, and the temperature of the outside air increases due to the absorption of heat, which is why the air blown from the outdoor unit of the air conditioner is hot.

4. The high-pressure and normal-temperature liquid refrigerant passes through the throttle valve. The function of the throttle valve is to adjust the flow and reduce the temperature and pressure. Therefore, after passing through the throttle valve, it becomes a low temperature and low pressure gas.
