Receiver Dryer: Description and Operation
RECEIVER-DRYERIt acts as a refrigerant storing container, receiving liquid and some 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.
