It helps to lower the temperature and pressure of the refrigerant.

Conditioner in the machine works almost like a refrigerator and a mechanical part which consists of many parts including configuring warm air from the car and throws it into the cold cabin inside the car.

This helps maintain a constant temperature in a small car where sometimes the air conditioner stops working or insufficient cooling air. However, just like other devices, the conditioner needs proper maintenance and repair respectively.
