Like the condenser, the car evaporator is designed to remove heat from your car. Unlike condensers though, car evaporators are located inside the passenger compartment. The evaporator receives cool liquid refrigerant which has been cooled by change of state in the condenser, the warm cabin air flows through the evaporator which causes the air to cool and liquid refrigerant to increase in temperature and change to vapour. The Vaporised cold, low-pressure air absorbs heat from the cabin and swaps it for cool air that is blown in.

Car evaporators
also act as dehumidifiers and protect the driver and passengers from pollen and dust. If your in-car AC is under performing, rest assured that it's no big deal replacing your evaporator. Car evaporators for every make and model are easily available your local motor factor - see our factor finder!
