Abstract: A method for controlling a refrigerator includes driving a compressor, operating a switching valve to allow a refrigerant to flow into at least one main expansion valve, opening a cool air passage connecting a refrigerating compartment to a main evaporator to cool the refrigerating compartment, operating the switching valve to switching a flow direction of the refrigerant into at least one deep-freezing expansion valve when a temperature of the refrigerating compartment is cooled to a temperature lower than a set temperature, thereby cooling the deep-freezing storage chamber, and operating the heater.
