Air conditioning (Receiver drier): Description and operation

Receiver drier

The receiver drier removes moisture and solid impurities from the refrigerant and also acts as a refrigerant reservoir.

Two screws secure the receiver drier to the LH front sidemember in the engine compartment. The receiver drier housing is manufactured in aluminium and contains zeolite desicant to absorb moisture. A mesh screen in the housing removes solid impurities. Inlet, outlet and trinary pressure switch connections are located in the top of the housing.

Liquid refrigerant enters the receiver drier, passes through the desicant and mesh screen, and through a tube to the outlet connection.
