THE GENERAL DATA

Put in action the engine of the car the compressor compresses a gaseous coolant to a high pressure, thus the coolant temperature considerably raises. Then compressed and нагретый the coolant moves in the condenser established on a radiator of system of cooling. The condenser cools a gaseous coolant which turns to a liquid. The liquid coolant arrives in the receiver / a dryer where from it water is endowed, then submits a liquid to the evaporator located in the block of a heater in salon of the car. In the evaporator the liquid coolant evaporates, passing in a gaseous state and reduces temperature of air arriving in salon. Further the gaseous coolant arrives to the compressor and the cycle repeats again.

The conditioner relay operates electric chains of the fan of the condenser and the conditioner compressor. Relay management is carried out by the engine management block. If the cooling liquid exceeds some temperature, the engine management block switches off the relay therefore the central air is switched off. At start-up of the engine or acceleration of the car the engine management block switches off the relay therefore the central air during 5 is switched off with.

The fan blows air through the evaporator core therefore the stream of the cooled air submitted to salon of the car increases. Frequency of rotation of the fan is defined by position of the switch of the fan and the block of resistors.

The conditioner compressor is a primary element of a central air of air. If the conditioner compressor fails, there is no compression and coolant moving on a contour of a central air of air. The conditioner compressor is put in action by a belt from a pulley of a cranked shaft.

Coupling of the compressor of the conditioner includes the compressor. Coupling has electromagnetic management.

The condenser is established before a radiator. The condenser fan increases air stream through the condenser.

The block of the fan / of the evaporator contains the fan engine, the conditioner relay, the core of the evaporator and the broad valve.
The evaporator core carries out functions of cooling and осушки air. At cooling of air the moisture from air is besieged on the evaporator and in car salon cooled dry air arrives.

The broad valve allows a liquid coolant to extend under a high pressure, entering into the evaporator. The valve passes certain quantity of a liquid coolant to exclude evaporator flooding.

Drained air can be reheated, passing through a heater radiator. The heater radiator heats up a hot cooling liquid passing through it.

In the receiver / a dryer the liquid coolant from the condenser where from it water leaves arrives and then the coolant arrives to the evaporator.

The central air is filled by coolant R-134a.
