11.Receiver Drier (LHD Model)
A: MECHANISM
The amount of refrigerant necessary to circulate in the system varies with change in the heat load.
The receiver drier stores part of the liquid refrigerant until an increased heat load requires its use
again. The receiver drier also has the following functions:
1) It removes bubbles from the liquid refrigerant. (If bubbles are present, the refrigerant passing
through the expansion valve varies in quantity, temperature, and pressure, resulting in insufficient
cooling.)
2) It removes moisture from the refrigerant.
3) It removes foreign substance from the refrigerant.
The receiver drier contains a strainer to remove foreign substance and desiccant to absorb mois-
ture from refrigerant.
