Evaporator (Heat Exchanger)

BUCUN BENGKEL : The Evaporator is the system component that actually does the cooling of the space or product. Therefore, it is a very important component. It may be defined as a device that absorbs heat into the refrigerant system. It is located in the area to be cooled. The heat is absorbed because of the latent heat of the refrigerant’s vaporization.

The liquid refrigerant inside the heat exchanger comes into contact with warm room air, causing it to evaporate; in other words, it absorbs heat from the surrounding air. The warm room air is drawn in by a fan, cooled, and sent back into the room.

The vapors move into the suction line. The accumulator holds any refrigerant which has not vaporized. The prevents liquid refrigerant from flowing into the suction line. To facilitate evaporation of the refrigerant, copper tubing with high thermal conductivity is used. The copper tubing is surrounded by thin fins to increase the surface area which comes in contact with the room air
