Receiver Dryer: Description and Operation
Purpose
-
Filter out chemical and mechanical impurities in the refrigerant
-
Reservoir for storage of refrigerant
-
Drying the refrigerant
Function
The liquefied refrigerant travels under pressure to the receiver/drier where it flows through a precious metal web to the filter block.
The pores of the filter block are matched precisely to the molecular size of the refrigerant so that the refrigerant can flow through the filter block.
All other substances are filtered out and deposited on this molecular screen. The purified refrigerant flows through a riser pipe to the expansion valve.
An observation glass on the receiver/drier allows the fluid level to be checked.
