Condenser

BUCUN BENGKEL : When the refrigerant is discharge from the compressor it is a hot, superheated vapor. It is ready to give up the heat that it collected in the evaporator, and also the heat gained during the compression process, to the medium used to cool the condenser. The purpose of the condenser is to remove the heat from the hot discharge gas and charge it to a liquid.

Refrigerant Flow at The Condenser

During this cooling process the sensible heat must first be removed from the vapor by the condenser cooling medium, lowering its temperature until it has reached the condensing temperature. The latent heat of condensing is then removed from the vapor, changing it to a liquid (condenses). In later model condensing units, extra rows are added to the condenser coil so that the liquid refrigerant can be cooled below the condensing temperature (sub cooled). Sub cooling is an essential part of any modern refrigeration condenser because it helps to increase the overall efficiency of the unit by reducing flash gas at the flow control device.

Condenser theory dedicates that the amount of heat given up by the refrigerant in the condenser must always equal the amount of heat gained by the cooling medium.
