A refrigerator comprising: a first freezing cycle device which includes a first compressor, a first condenser, a first expansion mechanism, and a first evaporator, through which refrigerant circulates; a first fan which circulates cool air in a freezing compartment to the first evaporator and the freezing compartment; a second freezing cycle device which includes a second compressor, a second condenser, a second expansion mechanism, and a second evaporator, through which the refrigerant circulates; a second fan which circulates cold air in a refrigerating compartment to the second evaporator and the refrigerating compartment; a third fan which blows outside air to the first condenser and the second condenser; an outside air sensor which detects the temperature of the outside air; and a control module which is connected to the outside air sensor and is configured to control the first compressor, the second compressor, the first fan, the second fan, and the third fan, characterized in that the control module is configured to perform a high-temperature initial simultaneous operation when an outside air temperature is an outside air set temperature or more, and is configured to perform a high-temperature initial alternation operation when a freezing compartment temperature exceeds a freezing compartment set temperature and a refrigerating compartment temperature is a refrigerating compartment set temperature or less during the high-temperature initial simultaneous operation, and wherein the control module is configured to drive the first compressor and the second compressor together and to drive each of the first fan, the second fan, and the third fan, during the high-temperature initial simultaneous operation, and is configured to alternately drive the first compressor and the second compressor during the high-temperature initial alternation operation. a first freezing cycle device which includes a first compressor, a first condenser, a first expansion mechanism, and a first evaporator, through which refrigerant circulates; a first fan which circulates cool air in a freezing compartment to the first evaporator and the freezing compartment; a second freezing cycle device which includes a second compressor, a second condenser, a second expansion mechanism, and a second evaporator, through which the refrigerant circulates; a second fan which circulates cold air in a refrigerating compartment to the second evaporator and the refrigerating compartment; a third fan which blows outside air to the first condenser and the second condenser; an outside air sensor which detects the temperature of the outside air; and a control module which is connected to the outside air sensor and is configured to control the first compressor, the second compressor, the first fan, the second fan, and the third fan, characterized in that the control module is configured to perform a high-temperature initial simultaneous operation when an outside air temperature is an outside air set temperature or more, and is configured to perform a high-temperature initial alternation operation when a freezing compartment temperature exceeds a freezing compartment set temperature and a refrigerating compartment temperature is a refrigerating compartment set temperature or less during the high-temperature initial simultaneous operation, and wherein the control module is configured to drive the first compressor and the second compressor together and to drive each of the first fan, the second fan, and the third fan, during the high-temperature initial simultaneous operation, and is configured to alternately drive the first compressor and the second compressor during the high-temperature initial alternation operation.
