Car Air Conditioning Evaporators

VS - Air Conditioning Evaporator - Valeo India


The outdoor air cools down as it passes through the evaporator fins, transferring the heat to the refrigerant.

The cool air is then blown into the cabin at temperatures between 2°C and 10°C

Air conditioning is often considered a means to cool air, but one of its most important roles is dehumidifying the air.

Reducing humidity levels in the cabin is essential in cold weather, as multiple passengers will quickly produce condensation on the vehicle’s windows. 

As cabin air moves through the A/C system, the condensation process on the evaporator fins effectively removes condensed moisture from the cabin air.

This condensation (water) is then collected and evacuated beneath the vehicle.
