METHOD FOR DETECTING OPERATION OF AIR CONDITIONER AND SYSTEM FOR DETECTING OPERATION OF AIR CONDITIONER

摘要

PROBLEM TO BE SOLVED: To provide a method for detecting an operation of an air conditioner and a system for detecting an operation of an air conditioner in which a characteristic electrical power variation generated at the time of starting an operation of the air conditioner can be caught.SOLUTION: An electrical power time sequence of total electrical power of an entire house is got by an input unit 111 of electrical power time sequence, and a rapid increasing of electrical power is detected when an electrical power variation equal to or more than a rising electrical power width occurs at an electrical power time sequence of the got entire electrical power and at a rising time width stored in a parameter memory unit 122. Under a condition in which the rising up of electrical power is detected, a small waveform is detected under application of the got electrical power time sequence, the maximum small waveform time width, the minimum small waveform time width, the maximum small waveform electrical power width and the minimum small wave form electrical power width stored in the parameter memory unit 122. It is determined whether or not the small waveform is detected continuously by two times or more. When the small waveform is detected continuously by two times or more, a time from the rapid increasing start time to the present time is assumed as an operation of the air conditioner and when the small waveform is not detected continuously by two times or more, it is assumed that the air conditioner is not operated.SELECTED DRAWING: Figure 6
