Where Does Car Refrigerant Usually Leak From?

[SanKingston]

Car air conditioning refrigerant leaks usually occur at the air conditioning pipe joints, expansion valve, compressor, evaporator box, and other locations. Below is additional information: 1. Components: A car air conditioning system is generally composed of the compressor, electromagnetic clutch, condenser, evaporator, expansion valve, receiver-drier, pipes, condenser fan, vacuum solenoid valve, idle speed controller, and control system. 2. Working Principle: When the compressor operates, it draws in low-temperature, low-pressure gaseous refrigerant from the evaporator. After compression, the refrigerant's temperature and pressure rise, and it is sent to the condenser. Inside the condenser, the high-temperature, high-pressure gaseous refrigerant transfers heat to the outside air passing through the condenser, causing it to liquefy into a liquid. When the liquid refrigerant flows through the throttling device, its temperature and pressure decrease, and it enters the evaporator. Inside the evaporator, the low-temperature, low-pressure liquid refrigerant absorbs heat from the cabin air passing through the evaporator, causing it to evaporate into a gas. The gas is then drawn back into the compressor to begin the next cycle.
