The evaporator’s main function is to absorb heat. As warmer air (from outside the vehicle, pulled in by the blower fan) passes over the aluminum fins of the cold evaporator fins, the cold low pressure liquid refrigerant that has just passed through the TXV will be heated, and turn into a gas – just like the liquid from the aerosol can.
At the same time, the moisture contained in the air condenses on its surface. Dust and pollen passing through stick to its wet surface and then drain off to the outside of the vehicle. The water can often be seen to drip from the bottom of the vehicle on humid days.
The ideal temperature of the evaporator is about ‘0’ degrees Centigrade (Celsius). The refrigerant enters the evaporator under low pressure, the warm air passing over the fins causing the refrigerant to boil. It absorbs a very large amount of heat. This heat is carried off with the refrigerant, leaving the passengers in the vehicle with cold, dry air.
