Receiver Dryer: Description and Operation

The receiver/dehydrator functions as a moisture separator and as an additional pulsation dampener that receives high pressure refrigerant liquid. The receiver/dehydrator only allows refrigerant and refrigerant oil to continue on to the TXV. A desiccant filter, mounted on the bottom of the receiver/dehydrator, acts as a drying agent for any moisture that may have accumulated in the system. The desiccant filter is serviceable.
