A: Refrigerant inlet (from condenser)

Function
(PC400-K5E2-042-K-00-A)
The receiver drier temporarily stores the high pressure and high temperature liquid refrigerant from the
condenser so that it can be supplied to the evaporator according to the need of cooling.
It sends the stored refrigerant from its bottom to the evaporator, allowing the refrigerant to be liquefied
completely ever when it contains bubbles due to the lower heat dissipation of the condenser.
The built-in filter and desiccating agent eliminate foreign substances in the circulation circuit and water
content in the refrigerant.
