A/C Receiver Drier - Operation






OPERATION

The A/C receiver/drier performs a filtering action to prevent foreign material that may be in the refrigerant from contaminating the A/C expansion valve and the A/C compressor. Refrigerant enters the A/C receiver/drier as a high-pressure, low temperature liquid. Desiccant inside the A/C 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 A/C receiver/drier acts as a reservoir to store surplus refrigerant.

The A/C receiver/drier is integral to the A/C condenser and has no serviceable parts.

CAUTION: The A/C condenser and receiver/drier must be replaced as an assembly if an internal failure of the A/C compressor has occurred. Failure to replace the A/C condenser and receiver/drier can cause serious damage to the replacement A/C compressor A/C Condenser - Removal .

The A/C receiver/drier cannot be repaired and the A/C condenser and receiver/drier must be replaced as an assembly, if the receiver/drier is leaking or damaged, or if an internal failure of the A/C compressor has occurred.
