Air compressor function

The air conditioning system in a vehicle is basically a compressor refrigerating machine with a circulation system in which a gaseous refrigerant is compressed to a smaller volume. This dissipates heat, which is discharged via the capacitor, which liquefies the refrigerant. Then it is fed into the evaporator where it must absorb heat from the environment again to return to its gaseous state. It can be cooled at the cooling fins of the evaporator, which passes through a fan into the interior of the vehicle. The pressure required to liquefy the refrigerant is generated in the air compressor which is usually driven by the vehicle engine. On the other hand, an electric air conditioning compressor has its own electric motor as a drive.The compressor often works according to the principle of an axial piston pump, in which the gaseous refrigerant is compressed and densified by piston arranged in the flow direction. There are also compressors which operate on the positive displacement principle. Well-known manufacturers of air compressors include Denso, Behr Hella, Valeo, Van Wezel, AC Delco and Waeco.

If the air compressor is defective

A defective air compressor results in impaired cooling performance, and ultimately in failure of the air conditioning. To rule out other causes, the air conditioning system should first be checked for a loss of coolant. A damaged compressor must be replaced in most cases, under certain circumstances the air conditioning compressor can be repaired.

Removing and Replacing the air conditioning compressor

With the necessary skills and some technical skill, you can replace a defective air conditioner compressor on your own. For this purpose, various other peripheral components such as the filter drier must be removed first and the coolant supply lines usually should be bridged. The compressor itself is attached by screw which must be loosened. When installing a new compressor, there should be a thorough flushing of the refrigerant supply lines to prevent dirt particles from getting into the cooling circuit, which can damage the air conditioner.
