The refrigerant compressor driven by the motor compresses the gaseous refrigerant, which is thereby heated up and routed to the condenser.
The refrigerant's compression heat is then withdrawn on the surface of the condenser.While cooling down, the refrigerant liquefies.
When the refrigerant flows through the fluid reservoir it is cleansed of any chemical and mechanical impurities.The water contained in the refrigerant is separated and collected.
The expansion valve sprays the cooled and liquefied refrigerant into the evaporator, which is located in the fresh-air flow. Here the refrigerant is 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 escapes into the open. The air dries out.
The refrigerant compressor 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.
