A car air conditioner is a very important part of a car (especially in summer), and unfortunately, it often happens that it stops working. Often the cause of a breakdown is the failure of the compressor for car air conditioners . And he is the main part of the entire climate control system. The whole system depends on how it works.
A special system is installed inside the compressor that divides it into two zones. High and low pressure areas. The low pressure zone draws in air, and the high pressure zone pumps air.
Compressors are of the type with reciprocating and rotary vane principle of operation. However, there are rare devices with a spiral type supercharger, as well as with a piston, which have a rotating swash plate. An air conditioning compressor with a tilted disc allows you to change the volume of the chambers, thereby changing the operation of the air conditioning system.
In reciprocating air conditioners, where refrigerant is pumped using a piston, the number of such pistons varies from one to several pieces. Compressors with several pistons are installed in modern air conditioners.
When the compressor is on, the engine power drops by about one and a half, and in some up to fifteen horsepower, and leads to increased fuel consumption. Therefore, it is worth choosing a compressor with the optimal power ratings specifically for your car.
The principle of operation of the compressor is to suck in itself refrigerant, which has a gaseous state and low pressure. Thanks to this, the oxygen in the system is cooled, and we feel a pleasant cold breeze. In some car brands, a container is installed that allows you to fill in liquid refrigerant, and already directly in it, the process of converting it into gas takes place. Very often air conditioner compressors fail due to wear of the intake valve, therefore, if the air conditioner is not working properly, you should pay attention to it.
