What is A/C Compressor

A car AC compressor is a device that is part of a vehicle’s air conditioning system, responsible for compressing and circulating refrigerant gas through the system.It is typically located at the front of the engine and is driven by a belt connected to the engine’s crankshaft.

When the car AC is turned on, the compressor receives a signal from the car’s electronic control module (ECM) to begin compressing refrigerant gas. As the gas is compressed, it increases in pressure and temperature. The high-pressure, high-temperature gas is then sent through the air conditioning system’s condenser, where it is cooled and condensed into a high-pressure liquid.

The liquid refrigerant then flows through the system’s expansion valve, where it is allowed to expand and become a low-pressure gas. This low-pressure gas flows through the evaporator, where it absorbs heat from the air inside the car, cooling it down. The cooled air is then blown into the car’s cabin by the system’s blower motor.

The car AC compressor is a critical component of the air conditioning system, and if it fails, the system will not be able to function properly. Symptoms of a failing compressor include a lack of cold air coming from the vents, unusual noises from the engine bay, and an increase in engine temperature.

The cold refrigerant flows into the evaporator core, which is located in or right at the dash. The blower motor blows air across the evaporator core.

As the warm air moves across the evaporator, the heat is removed from it, transferred to the refrigerant, and cold air enters the passenger compartment. Warm refrigerant leaves the evaporator, and heads back towards the A/C Compressor, where the cycle begins again.

Check Before Buy

However, before buying air conditioner compressors, it is necessary to consider three elements: quality, reliability and cost. Well-known air conditioning compressors from all over the world are Denso, Direct Industry, Danfoss, etc
