Receiver Dryer: Description and Operation
Receiver/Drier
The receiver/drier stores unnecessary refrigerant, filters the refrigerant, helps remove moisture from the refrigerant and retains any refrigerant vapor that
may leave the A/C condenser until it becomes a liquid. The receiver/drier is installed on the high-side the A/C system between the front and rear sections
of the A/C liquid line. The receiver/ drier can be serviced by removing the air cleaner housing.
The receiver/drier performs a filtering action to prevent foreign material in the refrigerant from contaminating the A/C expansion valve. Refrigerant
enters the receiver/drier as a high-pressure, low temperature liquid. Desiccant inside the receiver/drier absorbs any moisture which may have entered and
become trapped within the refrigerant system. In addition, during periods of high demand operation of the A/C system, the receiver/drier acts as a
reservoir to store surplus refrigerant.
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.
