1. A method for controlling a refrigerating apparatus including a non-azeotropic mixed refrigerant, the refrigerating apparatus including a first evaporator to supply cold air to a freezer compartment and a second evaporator to supply cold air to a refrigerating compartment, the first evaporator disposed upstream of the second evaporator in a direction of the non-azeotropic mixed refrigerant flow,
the method comprising:
operating a first operation in which includes, operating a compressor, operating a freezer compartment fan to blow air to the first evaporator, and operating a refrigerating compartment fan to blow air to the second evaporator;
in response to the freezer compartment reaching a first target temperature during the first operation or the refrigerating compartment reaching a second target temperature during the first operation, operating a second operation, the second operation including, continuously operating the compressor after the first operation, and stopping the freezer compartment fan or the refrigerating compartment fan corresponding to the freezer compartment that reaches the first target temperature or the refrigerating compartment that reaches the second target temperature, respectively; and
in response to the freezer compartment reaching the first target temperature during the second operation and the refrigerating compartment reaching the second target temperature during the second operation, operating a third operation, the third operation including, stopping both the refrigerating compartment fan and the freezer compartment fan after the second operation.
