The air-conditioning compressor is usually powered by the engine via a V-belt or ribbed V-belt. The compressor compresses and/or transports the refrigerant in the system. Different compressor designs are available.
The refrigerant is sucked in as a gas at low temperature from the evaporator; it is then compressed. It is then forwarded in a gaseous state at high temperature and high pressure to the condenser. The compressor can be dimensioned depending on the size of the system. The compressor is filled with special lubricating oil. Part of the oil circulates through the air-conditioning system with the refrigerant.
Behr Hella Service only has new compressor in its product range. This makes any used part return and deposit processing unnecessary, as it is usual among re-fabricated compressors.
