POWER CONSUMPTION ESTIMATION DEVICE AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To attain a high precise power consumption of an outdoor unit even if a watthour meter is not installed for every air conditioner.SOLUTION: A power consumption estimation device 10 includes an operation data acquisition part 11 for collecting actual data about an indoor unit operation factor and an outdoor unit frequency from an air conditioning controller 1 and storing them in an operation data accumulation part 16 as operation data; operation maximum frequency calculation part 12 for getting an outdoor unit frequency corresponding to data of 100% of indoor unit operation factor as the operation maximum frequency; and a consumption power calculating part 13 for calculating a present consumption power in reference to an outdoor unit rated capability, a present outdoor unit frequency and an operation maximum frequency. When there is no data of indoor unit operation factor of 100%, the operation maximum frequency calculation part 12 estimates an operation maximum frequency through regression analysis in view of a relation between the indoor unit operation factor and the outdoor unit frequency.SELECTED DRAWING: Figure 1
