GF83.40-P-2001T Refrigerant Circuit Function

Component Identification:

Function
Function The refrigerant compressor (A9), which is driven by the motor, compresses the gaseous refrigerant which is heated up during the process, routed into the condenser (1) and thus cooled down. The refrigerant's compression heat is then withdrawn on the surface of the condenser (1). While cooling down, the refrigerant liquefies.
When the refrigerant flows through the fluid reservoir (2), it is cleansed of any chemical and mechanical contamination.
The cooled and liquefied refrigerant flows through the expansion valve (3) into the evaporator core (4), which is located in the fresh- air flow. The refrigerant is then vaporized. Through this evaporation process heat is extracted from the fresh air flowing past from outside over the tube and fin system so that air cools down.

The air humidity carried along is converted to condensed water, which is routed to the outside. The air dries out.
The refrigerant compressor (A9) draws in the coolant which has turned gaseous through the collection of heat and compresses it again.
The pressure and refrigerant temperature sensor (B12/2) monitors the pressure and temperature of the refrigerant.
The refrigerant pressure sensor (B12) monitors the pressure of the refrigerant.
Cool air can be routed into the passenger compartment through the various air vents when the engine is running and the blower switched on. The degree of cooling intensity is dependent upon the previously set in-car temperature and the blower output.
