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.

Abstract: A refrigerating apparatus may include a main body having an interior space in which an article is accommodated, a door configured to open and close an opening of the main body, a compressor configured to compress a non-azeotropic mixed refrigerant, a condenser configured to condense the compressed non-azeotropic mixed refrigerant, a hotline provided at a contact portion between the main body and the door through which the condensed non-azeotropic mixed refrigerant flows, an expander configured to expand the non-azeotropic mixed refrigerant, heat of which is radiated by the hotline, and an evaporator configured to evaporate the expanded non-azeotropic mixed refrigerant to supply cold air to the interior space. According to such structure, even when the non-azeotropic mixed refrigerant is used, a function of the hotline to prevent dew formation may be normally performed with hot refrigerant.
