PURPOSE:To provide a refrigerator which employs a non-azeotropic mixt. of bromotrifluoromethane and 1,2-dichlorotetrafluoroethane as refrigerant and has a high efficiency of refrigeration. CONSTITUTION:The refrigerator employs a non-azeotropic mixed refrigerant compsn. obtained by blending bromotrifluoromethane with 1,2-dichlorotetrafluoroethane, as refrigerant to be used within a temp. range of regrigeration operation. Refrigerating power can be controlled within a wide range by varying the blend ratio of the refrigerant to be circulated. |
