The role of the AC compressor in cooling your car!

In this article, we will look at the role of the AC compressor in a car's air conditioning system. While your car's air conditioning system is made up of many different components, the AC compressor serves as one of the central components that creates the necessary cycle for the system. Without it, your entire AC system would not be able to perform its primary function - creating cool air in your car.

The main role of the AC compressor is to apply the necessary pressure to the car's coolant to activate the heat transfer characteristics and change the temperature, and also to absorb polluted air inside the car's cabin.

All of this allows you to stay cool in your car during the hot months and have a clean windshield during the cooler months.

To begin with, it is important to know the relationship between the AC compressor and the refrigerant.

A tried and tested refrigerant is Freon, a liquid that helps to expel hot air from the cold. This refrigerant and the compressor are a vital duo that work together to help each other.

The most commonly used and widespread is the SWASH plate type AC compressor.

Are you curious about how it works?

A timing belt and V-belt drive the compressor, which is attached to the engine block of the vehicle. When the AC system is turned on, the belt drive starts moving with an electromagnetic clutch. The switch plate oscillates 6 double-ended pistons, which are responsible for the intake and compression of the air flow.

It is important to note that the AC compressor draws in gas from the refrigerant through the evaporator, which causes a pressure drop. The reduced pressure causes the refrigerant to evaporate at a lower temperature before the compressor takes in this cold vapor and compresses it. During compression, the refrigerant gas is heated and flows through pipes to the condenser. Here, it re-liquefies and releases heat as it cools. It then returns to its gaseous state in the evaporator before being sucked into the AC compressor.
