A refrigerator includes a control module which controls a first compressor, a second compressor, a first fan, a second fan, and a third fan, in which the control module performs a high-temperature initial simultaneous operation when the outside air temperature is at the outside air set temperature or more, performs a high-temperature initial alternation operation when the freezing compartment temperature is at the freezing compartment set temperature or less and the refrigerating compartment temperature is at the refrigerating compartment set temperature or less during the high-temperature initial simultaneous operation. The control module drives the first compressor and the second compressor together during the high-temperature initial simultaneous operation, and alternately drives the first compressor and the second compressor during the high-temperature initial alternation operation.

Refrigerator

A refrigerator that includes a compressor configured to compress a refrigerant; a condenser configured to condense the refrigerant; a first evaporator that is configured to evaporate the refrigerant, the evaporated refrigerant being configured to cool a refrigerating compartment; a second evaporator that is configured to evaporate the refrigerant, the evaporated refrigerant being configured to cool a freezing compartment; a first heat exchanger; a refrigerating-compartment expansion device that is coupled to the first heat exchanger and that is configured to expand the refrigerant and provide the expanded refrigerant to the first heat exchanger; a second heat exchanger coupled to the second evaporator; and a freezing-compartment expansion device that is coupled to the second heat exchanger and that is configured to expand the refrigerant and provide the expanded refrigerant to the second heat exchanger, wherein the first heat exchanger is configured to cool the second heat exchanger is disclosed.
