- Compressor: The compressor is the heart of the air conditioning system. It compresses the refrigerant gas and sends it to the condenser.
- Condenser: The condenser is a heat exchanger that cools the compressed refrigerant gas and turns it into a liquid.
- Evaporator: The evaporator is another heat exchanger that absorbs heat from the air inside the car and turns it into a cool, refreshing breeze.
- Expansion valve: The expansion valve controls the flow of refrigerant into the evaporator.
- Receiver-drier: The receiver-drier stores refrigerant and removes moisture from the system.
- AC lines: AC lines connect the components of the air conditioning system and allow the refrigerant to flow between them.
- AC compressor clutch: The AC compressor clutch engages and disengages the compressor, depending on whether or not the air conditioner is turned on.
- AC compressor clutch relay: The AC compressor clutch relay controls the flow of power to the AC compressor clutch.
- AC control head: The AC control head allows the driver to select the desired temperature and fan speed for the air conditioning system.
- AC evaporator temperature sensor: The AC evaporator temperature sensor measures the temperature of the air coming out of the evaporator and signals the AC control head to adjust the fan speed and compressor speed accordingly.
- AC refrigerant: AC refrigerant is the fluid that circulates through the air conditioning system and absorbs heat from the air inside the car.
