Receiver Dryer: Description and Operation

Receiver/Drier With Refrigerant Lines - Typical:

A receiver/drier is used on 2.4L and RHD models. The receiver/drier is mounted on the right side of the engine compartment and is located between the A/C condenser outlet and A/C evaporator inlet.

The receiver/drier cannot be repaired. If the receiver/drier is faulty or damaged, or if the refrigerant system has been contaminated or left open to the atmosphere for an indeterminable period of time, or if the A/C compressor has failed, the receiver/drier must be replaced.

The receiver/drier performs a filtering action to prevent foreign material in the refrigerant from contaminating the expansion valve. A desiccant bag is mounted inside the receiver/drier canister to absorb any moisture which may have entered and become trapped within the refrigerant system. In addition, during periods of high demand air conditioner operation, the receiver/drier acts as a reservoir to store surplus refrigerant. Refrigerant enters the receiver/ drier as a high-pressure, low temperature liquid.
