A/C Compressor

The A/C compressor, short for air conditioning compressor, is a component of a car’s air conditioning system. It is responsible for pressurizing and circulating the refrigerant that cools the air inside the vehicle. The compressor is driven by the engine’s belt and pulley system, and it is responsible for compressing the refrigerant gas, which causes it to become hot, and then pumping it through the car’s air conditioning system. The compressed refrigerant is then passed through the condenser, which cools the refrigerant and turns it back into a liquid. The cooled liquid refrigerant is then sent through the evaporator, which is located inside the car’s cabin. The evaporator absorbs heat from the air inside the vehicle, which cools the air and sends it through the car’s vents to provide cool air inside the vehicle. The compressor is a key component of the air conditioning system that is responsible for circulating the refrigerant throughout the system to cool the air inside the vehicle.
