Abstract: A method for measuring the amount of electric power consumption of a refrigerator comprises the steps of: measuring the amount of electric power consumption and a time of a defrosting cycle in a refrigerator during operation of a defrosting heater after starting a measurement of the amount of electric power consumption and during two cycles of operating a compressor after operating the defrosting heater; measuring the average of electric power consumption per cycle and the average of operating time per cycle in the refrigerator during performance of refrigerating cycles after the defrosting cycle; and calculating the total amount of electric power consumption of the refrigerator using the amount of electric power consumption during the performance of the defrosting cycle, the average amount of electric power consumption of the refrigerator during the performance of the refrigerating cycle, the time for performing the defrosting cycle, and the average time for performing the refrigerating cycle.
