GENERAL INFORMATION

Arrangement of elements of central air of air on the car

1–compressor;
2–compressor coupling;
3–kondensor;
4–receiver;
5–kondensor fan;
6–heater block;

7–switch of double pressure;
8–pipe No. 1;
9–pipe No. 2;
10-pipe of low pressure;
11-pipe of a high pressure;
12-a soaking-up pipe

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 within 5 seconds 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 located on the left side of the engine and 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 block of the fan / evaporator contains the engine of the fan, the relay of the conditioner, the core of the evaporator and the broad valve.

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.

Prevention

Do not add coolant R-12 in central air intended for coolant R-134a. These coolants should not mix up, as it will lead to failure of central air of air.

Do not allow contact of a coolant to skin.

At work near central air put on goggles.

At coolant hit on skin or in eyes do not pound the struck place, immediately wash out cold water not less than 15 minutes and address to the doctor. Self-treatment is not allowed.

The gaseous coolant is heavier some air and rather quickly should gather below, for example under the car.

At carrying out welding works near air central air always delete from it a coolant. Electric welding near pipelines with a coolant can cause coolant decomposition under the influence of ultra-violet radiation.

Do not subject central air detail to influence of high temperature or an open flame. The overheat can lead to pressure increase in system and to ignition.
