The conditioner

Gaseous хладон it is compressed by the compressor approximately the same as it occurs in a house refrigerator. The compressor is put in action by cranked shaft of the engine by means of клинового a belt. At compression хладон becomes liquid and gets to the evaporator (radiator). Inside хладон evaporates and thanks to it begins capable to absorb heat. Air passing through the evaporator gets to salon the cooled. Through the condenser near to 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 through the condenser.

Клиновой or поликлиновой a belt

For reliable work of the conditioner should be correctly tense клиновой a belt of the compressor of the conditioner. At models with the 6-cylinder engine instead of клинового costs поликлиновой a belt with the automatic tension device. In more details about belt drives it is written in section the Generator.

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