Receiver Dryer: Description and Operation

RECEIVER/DRIER
The receiver/drier is mounted in a bracket secured to the right front strut tower in the engine compartment. The receiver/drier is connected between the front and rear sections of the liquid line between the condenser outlet and the 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 or if the A/C compressor has failed, it must be replaced.

The receiver/drier performs a filtering action to prevent foreign material in the refrigerant from contaminating the expansion valve. Desiccant inside the receiver/drier canister absorbs 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.
