Car air conditioning compressors are devices that compress the refrigerant from a gaseous state and send it to the condenser, where it cools and changes to a liquid state. The liquid refrigerant passes through the evaporator, where it absorbs heat from the cabin air and returns to a gaseous state. The cycle is repeated continuously to keep the air conditioning running. The operation of air conditioning compressors depends on the type of compressor the vehicle has. The most common types are the piston compressor, the rotary compressor, and the vane compressor. There are different brands of air conditioning compressors, some of the most popular brands are: - Denso: This is a Japanese company that manufactures high-quality, energy-efficient compressors.
