Abstract

Disclosed is to provide a refrigerator system using non-azeotropic refrigerants, its cooling capability is improved at starting up and/or at going up interior room temperature. On a single-stage type refrigerating system using non-azeotropic refrigerant, composing with a compressor (1), a condenser (2), and an evaporatior (10),heat exchanging between returned-refrigerant from evaporator and high-pressure refrigerant toward evaporator, electromagnetic valves (5-1 to 5-5) of capillary tubes (6-1 to 6-5) as expansion valves of evaporator are fully open, at moments of large load neede such as at starting up, the system is controlled flux of referigerant gas and pressure of it by closing them one by the other corresponding to going down of interior room temperature. As the state of interior room temperature is high and low boiling point constituent is not condensed, cooling capality of high boiling point referigerant performs in maxium.
