Abstract
A refrigerator includes a motor to drive a compressor, an output current detector to detect an output current flowing to the motor, a compressor controller to calculate a power consumed in the compressor based on the detected output current, a plurality of power consuming units, and a main controller to receive the calculated compressor power consumption information, and when the plurality of power consuming units operate, to calculate a final power consumption using power consumption information stored for each power consuming unit and the calculated compressor power consumption information. Accordingly, computation of a power consumption may be simply performed.
