Function diagram, function
The refrigerant compressor (1) driven by the motor compresses the gaseous refrigerant, which causes it to be heated up, and sends it into the condenser (2) where it is cooled down.
The surface of the condenser (2) is used to withdraw the compression heat from the refrigerant. While cooling down, the refrigerant liquefies.
When the refrigerant flows through the fluid reservoir (3) it is cleansed of any chemical and mechanical impurities.
The cooled and liquefied refrigerant flows through the expansion valve (4) into the evaporator (5), 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 honeycomb system. This process cools down the fresh air.

The air humidity carried along is converted to condensed water, which escapes into the open. The air dries out. The refrigerant compressor (1) aspirates the refrigerant which has turned gaseous on account of the heat absorption and then compresses it yet again.

When the engine is running and the blower switched on, the interior can be supplied with cooled air through the various air outlets. Cooling intensity is dependent upon the preset in-car temperature and blower setting.
