Abstract

PURPOSE:To estimate roughly electric power consumption with a simple structure by counting and detecting the drive time of an equipment which consumes a major part of electricity in the device and then by displaying the electric power consumption by the result of the counting and detection. CONSTITUTION:According to the operation of an air conditioner, etc., its power consumption is monitored at any time and upon occasion, a change-over switch is operated to display the power consumption. Namely, once a signal starting compressor 4 is generated, gate 7 is opened to drive compressor driving-time integrating counter R1, which counts and stores the compressor driving time with reference pulses from unit time pulse generator 8. In case that display change-over switch 5 indicates power consumption display, the contents of register R2 stored previously with the power consumption per time of the compressor and those of integrating counter R1 are multiplied mutually by multiplier MPX, whose output is displayed on display device 9 via display device buffer DB. Thus, the power consumption can roughly be estimated with the simple structure.
