Abstract: A refrigerating system may include a compressor configured to compress a non-azeotropic mixed refrigerant, a condenser configured to condense the compressed non-azeotropic mixed refrigerant, a three-way valve configured to branch the non-azeotropic mixed refrigerant condensed by the condenser, a first evaporator configured to supply cold air to a first interior space, a second evaporator configured to supply cold air to a second interior space at a temperature higher than at a temperature of the first interior space, and a capillary tube configured to expand the non-azeotropic mixed refrigerant branched by the three-way valve and supply the expanded non-azeotropic mixed refrigerant to at least one of the first evaporator or the second evaporator. With such features, a high-efficiency refrigerating system to which the non-azeotropic mixed refrigerant is applied may be implemented.

Abstract: A method for controlling a refrigerating system using a non-azeotropic mixed refrigerant is provided. The refrigerating system may include a first evaporator configured to supply cold air to a freezer compartment located upstream and a second evaporator configured to supply cold air to a refrigerating compartment located downstream, based on a flow direction of the non-azeotropic mixed refrigerant. The method may include a first operation comprising operating a compressor, a freezer compartment fan to blow air to the first evaporator, and a refrigerating compartment fan to blow air to the second evaporator; a second operation comprising when the freezer compartment reaches a target temperature or the refrigerating compartment reaches a target temperature, continuously operating the compressor, and stopping the freezer compartment fan or the refrigerating compartment fan corresponding to one of the freezer compartment or the refrigerating compartment that reaches the target temperature; and a third operation comprising when both the freezer compartment and the refrigerating compartment reach the target temperatures, turning off both of the refrigerating compartment fan and the freezer compartment fan and stopping the compressor.
