Where Does the Highlander's Air Conditioning Usually Leak Refrigerant?

[Ophelia]

The Highlander's air conditioning system usually leaks refrigerant from the joints of the air conditioning pipes, the expansion valve, the compressor, or the evaporator. Additional Information: 1. Air Conditioning Components: The car air conditioning system generally consists of the compressor, the electronically controlled clutch, the condenser, the evaporator, the expansion valve, the receiver-drier, the pipes, the condenser fan, the vacuum solenoid valve, the idle speed controller, and the control system. 2. Working Principle: When the compressor is running, it sucks in low-temperature, low-pressure gaseous refrigerant from the evaporator. After compression, the temperature and pressure of the refrigerant 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 and liquefies, turning into a liquid. The liquid refrigerant flows through the throttling device, where its temperature and pressure decrease, and it enters the evaporator. Inside the evaporator, the low-temperature, low-pressure liquid refrigerant absorbs heat from the inside air passing through the evaporator and evaporates, turning into a gas. The gas is then sucked back into the compressor for the next cycle.
