Operation theory of refrigeration cycle components ■Condenser 1) Role: A device which radiates heat to the outside (water/air) to make liquid state for the high temperature / high pressure gas refrigerant discharged from compressor 2) Types A. Air-cooling Type : Condense air by circulating naturally or manually. 1) Natural Convection Type : Used for the household refrigerator which has small condensing capacity.
  • Page 24 PRODUCT SPECIFICATIONS ■Evaporator 1. Role: As the low pressure liquid refrigerant flowed from capillary absorbs heat inside of the refrigerator, it becomes low pressure gas and refrigerate the foods. 2. Theory: The low pressure refrigerant flowed to evaporator operates cooling which takes ambient evaporated potential heat with maintaining the evaporation up to evaporate completely.
