ICE-HEAT ACCUMULATION TYPE AIR CONDITIONER

摘要

PROBLEM TO BE SOLVED: To perform a demand control of electric energy of an ice-heat accumulating type air conditioner based on an estimate of thermal load in a residential space and properly control the operation of the air conditioner. SOLUTION: A heat demand curve 5 is estimated through data analysis of heat demand time series basic data that have been accumulated, and heat demand time series data that show the heat load state in a residential space at present, and changes in electric power consumption of a device is forecasted from the estimated result. The period of time near the peak of the electric power consumption is designated as a demand control time band 6 and heat release operation of a heat accumulating device 12 and operational state of a heat source device 11 are delicately controlled so as to cut down part of the electric power consumption.
