System and method for measuring amount of electric power consumption in a refrigerator

A method for measuring an amount of electric power consumption of a refrigerator, comprising the steps of:

• measuring the amount of electric power consumption and a time of a defrosting cycle in a refrigerator during an 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 an average of electric power consumption per a cycle and an average of operating time per a cycle in the refrigerator during an operation of refrigerating cycles after the defrosting cycle;
• and
• calculating a total amount of the electric power consumption of the refrigerator as follows:
• ##EQU4## where n=1, 2, or 3, k=1 or 2, Wh represents the total amount of the electric power consumption of the refrigerator, Whdef is the amount of electric power consumption during the defrosting cycle, DT represents a defrosting cycle time, CT is the average operation time per cycle, and Whln is the average amount of electric power consumption per refrigerating cycle.
