Receiver Dryer: Description and Operation
RECEIVER/DRIER - FRONT
The filter-drier is mounted in a bracket secured to the right front strut tower in the engine compartment. The filter-drier is connected between the
front and rear sections of the liquid line between the condenser outlet and the evaporator inlet. The filter-drier cannot be repaired. If the filter-drier
is faulty or damaged, or if the refrigerant system has been contaminated or left open to the atmosphere for an indeterminable period, it must be
replaced.
The filter-drier performs a filtering action to prevent foreign material in the refrigerant from contaminating the expansion valve. A desiccant bag is
mounted inside the filter-drier canister to absorb any moisture which may have entered and become trapped within the refrigerant system. In
addition, during periods of high demand air conditioner operation, the filter-drier acts as a reservoir to store surplus refrigerant. Refrigerant enters
the filter-drier as a high-pressure, low-temperature liquid.
