Gaseous хладон it is compressed by the compressor approximately the same as it occurs in the home refrigerator. The compressor is put in action by cranked shaft of the engine by means of a maple belt. At compression хладон becomes liquid and gets to the evaporator (radiator). Inside хладон evaporates and thanks to it becomes capable to absorb heat. Air passing through the evaporator gets to salon the cooled. Via the condenser near a radiator of water cooling in a motor compartment the coolant gets back to the compressor. For increase in condensation the fan of system of cooling constantly blows air via the condenser.

Maple or poliklinovy belt

For reliable operation of the conditioner the belt of the compressor of the conditioner should be correctly tense maple. Models with the 6-cylinder engine instead of the maple have poliklinovy a belt with the automatic tension device. In more detail about belt drives it is written in the section Generator.

 Help: conditioner repair in house conditions – except for control of a maple belt – is impossible. And even from masterful Audis repair similar systems everyone can not. Therefore at defects it is necessary to find out at first, whether employees have the corresponding qualification, and to address only in such workshops.
