Receiver Dryer: Description and Operation
RECEIVER/DRIER-A/C
DESCRIPTION
The receiver/drier (1) stores unnecessary refrigerant, filters the refrigerant, helps remove moisture from the refrigerant and retains any refrigerant vapor
that may leave the A/C condenser (2) until it becomes a liquid. The receiver/drier is installed on the high-side of the A/C system and is connected
directly to the right end of the A/C condenser. The receiver/drier can be easily serviced by removing the grille and air cleaner housing.
OPERATION
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 an internal failure of the A/C compressor has occurred, the
receiver/drier must be replaced.
