Condenser and Receiver Drier

Condenser And Receiver Drier







The condenser transfers heat from the refrigerant to the surrounding air to convert the vapor from the A/C (air conditioning) compressor into a liquid. A receiver drier module, integrated onto the LH (left-hand) side of the condenser, incorporates a filter and a desiccant to remove solid impurities and moisture from the refrigerant. The receiver drier module also functions as a reservoir for liquid refrigerant, to accommodate changes of heat load at the evaporator.

The condenser is installed immediately in front of the radiator. The condenser on 3.0L diesel models has a smaller frontal area than those on 4.2L and 4.4L models, but is of a similar design.

The condenser is classified as a sub-cooling condenser and consists of a fin and tube heat exchanger installed between two end tanks. Divisions in the end tanks separate the heat exchanger into a three pass upper (condenser) section and a single pass lower (sub-cooler) section, which are interconnected by the receiver drier module. The desiccant cluster and the filter in the receiver drier module are serviceable items retained in position by a threaded plug.
