  • Page 19: Operation Theory Of Refrigeration Cycle Components

    PRODUCT SPECIFICATIONS 2-7-2. Operation theory of refrigeration cycle components ■Condenser 1) Role: A device which radiates heat to the outside of the refrigerator. As this heat is dispersed, the high temperature/ high pressure vapor refrigerant changes to a liquid state. 2) Types A.
  • Page 20 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.
