Car Air Conditioning and Its Operation
Car air conditioning is an essential system that provides a comfortable driving experience, especially during hot summer days. The system regulates the temperature and humidity levels inside the car, making it ideal for long drives. If you are still getting familiar with this system’s operations, this article will provide you with all the information you need.
The car air conditioning system comprises components such as a compressor, condenser, evaporator, and expansion valve. These work together in a closed loop to cool down the cabin’s air.
When you turn on your car’s AC, the compressor draws refrigerant gas from the evaporator and compresses it into a high-pressure liquid that flows through the condenser. The refrigerant then cools down as it passes through the condenser and turns into low-pressure gas before moving back to the evaporator, which absorbs heat inside your vehicle.
What Causes a Terrible Air Conditioning Smell?
