Receiver Dryer: Description and Operation

Connected to the condenser assembly outlet pipe, the sealed receiver-dehydrator assembly acts as a refrigerant storage container receiving R134a liquid.

At the center of the receiver-dehydrator is the desiccant which acts as a drying agent for moisture that may have entered the system. The filter and baffle on the upper end of the component is for retaining the desiccant bags and removing contamination from the A/C system.
