Defrost Process – Part two
Air defrosting In refrigeration, air defrost is an effective method of combating ice build-up in evaporators. This process uses the air in the chamber itself to defrost the frost efficiently. Its suitability is intensified in chambers above 4ºC, as at lower temperatures its effectiveness is reduced. The system starts with the closing of the liquid solenoid valve, which stops the refrigerant flow to the evaporator and to be emptied by the compressor until it stops. In this case the fans recirculate the air...
