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.

Abstract: A refrigerator includes a compressor, an input current detector to detect input current of alternating current (AC) power inputted to the refrigerator, a converter to convert the inputted AC power into direct current (DC) power, a capacitor to store the converted DC power, an inverter to output AC power using the converted DC power for driving of the compressor, a DC terminal voltage detector to detect voltage at two terminals of the capacitor, and a compressor microcomputer to control the inverter and to calculate refrigerator power consumption based on the detected input current and the detected DC terminal voltage. The refrigerator enables simplified power consumption calculation.
