Patent ID: 10414244

Abstract:
A refrigeration system includes a primary evaporator that cooperates with a compressor, which compresses first refrigerant containing lubricant oil, to form a refrigeration cycle that circulates the first refrigerant. At the primary evaporator, the first refrigerant absorbs heat from second refrigerant and is thereby evaporated. The refrigeration system further includes a condenser, at which the second refrigerant releases heat to the first refrigerant and is thereby condensed. The refrigeration system also includes a secondary evaporator that cooperates with the condenser to form a refrigerant circulation circuit, in which the second refrigerant is circulated. At the secondary evaporator, the secondary evaporator absorbs heat from a primary cooling subject and is thereby evaporated. A refrigerant flow passage of the primary evaporator and a refrigerant flow passage of the condenser are independently formed, so that the refrigeration cycle and the refrigerant circulation circuit are independently formed.
