Refrigerant circuit, function

S83.30-2034-12

1 A/C compressor
2 Condenser
3 Receiver/drier
4 Expansion valve
5 Evaporator

A High pressure (gaseous)
B High pressure (liquid)
C Low pressure (liquid)
D Low pressure (gaseous)

The A/C compressor (1) is driven by the engine and compresses the gaseous refrigerant, which is heated during this process and flows to the condenser (2).
The heat in the refrigerant resulting from compression is absorbed by the surface of the condenser (2). The refrigerant liquefies as it cools.
As it flows through the receiver/drier (3) the refrigerant is purified of any chemical or mechanical impurities.
The expansion valve (4) sprays the cooled liquid refrigerant into the evaporator (5), which is located in the stream of fresh air. Here the refrigerant evaporates. This evaporation process absorbs heat from the fresh air flowing by on the outside through the tube and honeycomb system cooling the air.

The moisture entrained in the air condenses and is drained outside. The air is dried. The A/C compressor (1) sucks in the refrigerant which has become gaseous due to the heat absorbed and compresses it again.

Cooled air can be routed to various outlet openings in the passenger compartment with the engine running and blower switched on. The intensity of the cooling depends on the temperature set for the passenger compartment and the blower power.
