Operation of the conditioner

The compressor of cooling is set in motion through klinoremenny transfer from a bent shaft of the engine. It compresses working gas of a contour of the conditioner up to the pressure of 30 bars. At the same time gas heats up. In the condenser cooling of heated gas with the air passing through it is made. In a consequence of cooling of gas it is condensed and turns into liquid. Under high pressure liquid passes through a throttle. Owing to pressure decrease liquid is cooled and evaporates. Passing through the evaporator, the cooled liquid selects heat from the air blown through it. Air is cooled and comes to interior of the car. The working body in gaseous state under low pressure comes to the compressor.

The description of repair of the conditioner is not provided here. Repair has to be made on specialized HUNDRED. In particular, it is not allowed to open a cooling contour as the contact with liquid can lead to a burn.
