Abstract

A non-azeotropic mixed refrigerant cycle and a refrigerator equipped with the same are disclosed. The non-azeotropic mixed refrigerant cycle includes a first refrigerant tube (P1) to guide a refrigerant from a condenser (2) to a first evaporator (4), a second refrigerant tube (P2) to guide the refrigerant from the first evaporator to a second evaporator (5), a third refrigerant tube (P3) to guide the refrigerant from the second evaporator to a compressor (1). A downstream portion of the first refrigerant tube is arranged within the second refrigerant tube, to form a first heat exchanger (7) having a double tube structure. An upstream portion of the first refrigerant tube is arranged within the third refrigerant tube, to form a second heat exchanger (8) having a double tube structure.
