System Components - Functional: Receiver-Dryer

The sealed receiver-dryer assembly is connected to the condenser outlet pipe. It acts as a refrigerant storing container, receiving liquid, vapor, and refrigerant oil from the evaporator.

At the bottom of the receiver-dryer is the desiccant, which acts as a drying agent for the moisture that may have entered the system. An oil bleed hole is located near the bottom of the receiver-dryer outlet pipe to provide an oil return path to the compressor. The receiver-dryer is serviceable only as an assembly.
