Air central air
Put in action the car engine the compressor compresses a gaseous coolant to a high pressure, thus the coolant temperature considerably raises. Then the compressed and warm coolant moves in the condenser established on a radiator of system of cooling. The condenser cools a gaseous coolant which turns into liquid. The liquid coolant arrives in the receiver / dryer where from it water is endowed, then submits liquid to the evaporator located in the block of a heater in salon of the car. In the evaporator the liquid coolant evaporates, passing to 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 relay of the conditioner operates electric chains of the fan of the condenser and the conditioner compressor. The management of the relay is carried out by the control unit the engine. If cooling liquid exceeds some temperature, the control unit the engine switches off the relay therefore central air is switched off. At start-up of the engine or car acceleration the control unit the engine switches off the relay therefore central air during 5 pages is switched off.
The fan blows air via 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 compressor of the conditioner is primary element of central air of air. If the compressor of the conditioner fails, there is no compression and coolant moving on a contour of central air of air. The compressor of the conditioner is put in action by a belt from a pulley of a cranked shaft.
Coupling of the compressor of the conditioner turns on the compressor. Coupling has electromagnetic management.
The condenser is established before a radiator. The fan of the condenser increases an air stream via the condenser.
The core of the evaporator carries out functions of cooling and an air osushka. When cooling air moisture from air is besieged on the evaporator and in salon of the car the cooled dry air arrives.
The broad valve allows a liquid coolant to extend under a high pressure, entering into the evaporator. The valve passes a certain quantity of a liquid coolant to exclude evaporator flooding.
The drained air can be reheated, passing through a heater radiator. The radiator of a heater heats up hot cooling liquid passing through it.
In the receiver / dryer the liquid coolant from the condenser where from it water is removed arrives and then the coolant arrives to the evaporator.
Central air is filled with coolant R–134a.
