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 high-temperature outside air, so that the low-temperature and low-pressure liquid absorbs the heat from the outside and evaporates, and the refrigerant becomes a low-temperature and low-pressure gas; The heat is exchanged, and 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 outside air at a lower temperature relative to the refrigerant. At this time, the air absorbs the refrigerant. The temperature is up. As a result, the refrigerant cools down and becomes a high-pressure and normal-temperature liquid, while the outside air increases in temperature due to heat absorption. This is why the wind blown out by 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 rate, reduce temperature and pressure. Therefore, after passing through the throttle valve, it becomes a low-temperature and low-pressure gas.
