Abstract: A control method for a refrigerator includes sensing a temperature of a storage room; operating a cool air supply at a cooling power when the sensed temperature of the storage room is equal to or above a first reference temperature; operating the cool air supply at a delay power, which is less than the cooling power, when the sensed temperature of the storage room is equal to or below a second reference temperature, which is less than the first reference temperature while the cool air supply is operating at the cooling power; and adjusting the cooling power or the delay power of the cool air supply according to the temperature of the storage room while the cool air supply is operating at the delay power, and operating the cool air supply at the determined adjusted cooling power or delay power.

Abstract: 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.
