Refrigerant System (IHKS and IHKA)

The Refrigerant System transfers heat from the vehicle interior to the outside atmosphere providing the heater assembly with dehumidified cool air. The system is a sealed, closed loop, filled with a charge weight (350 grams) of R134a refrigerant as the heat transfer medium. Oil is added to the refrigerant to lubricate the internal components of the compressor.

The refrigerant system consists of the following components:

• R134a Refrigerant and Lubricant
• Compressor
• Evaporator
• Condenser
• Receiver/Drier
• Expansion Valve
• Cooling Fan
• Pressure Transducer
• Evaporator Temperature Sensor
• Refrigerant Lines
