Abstract
A refrigerator includes a compressor, a cold storage medium, a power supply to convert AC power supplied from an outside of the refrigerator, and to receive DC power during interruption of electric power, and a controller to perform a control operation to supply a cooling capacity to an interior of the refrigerator by driving the compressor based on the supplied AC power when no interruption of electric power occurs, and to perform a control operation to supply a cooling capacity to the interior of the refrigerator based on the supplied DC power and the cold storage medium during the interruption of electric power. Accordingly, consumption of electric power during interruption of electric power is reduced.
