The Expansion device plays an important role in the Air Conditioning system. It is used to absorb the heat released and to provide cool air into your Air Conditioning unit. It has aluminum fins which the hot air passes through and the moisture in the Air Condenses on the surface. The hot air passing through the Evaporator boils the refrigerant which helps the Evaporator absorb a great amount of heat. The absorbed heat is let out of the vehicle along with the refrigerant. The Expansion device has three pressure points to regulate the amount of refrigerant entering the Evaporators. They are the Evaporator, bulb and the spring.
