METHOD OF CALCULATING ACTUAL USE AMOUNT OF FUEL ELECTRIC POWER, METHOD OF CALCULATING BURDEN OF FUEL ELECTRIC POWER CHARGE, DEVICE FOR CALCULATING ACTUAL USE AMOUNT OF FUEL ELECTRIC POWER AND DEVICE FOR CALCULATING BURDEN OF FUEL ELECTRIC POWER CHARGE

摘要

PROBLEM TO BE SOLVED: To provide a method or a device capable of determining an appropriate cost burden by a simple configuration and achieving fair energy distribution so as to effectively use energy.;SOLUTION: The method of calculating actual use amount of the fuel electric power of each household is used in the case for adopting a hot water supply system including a water heater A collectively used by a plurality of households H1, H2, H3 and a plurality of water heaters B separately used by the plurality of households H1, H2, H3 and delivering hot water of which the temperature is raised by the water heater A to each of the households H1, H2, H3 via the water heaters B. In this method, on the basis of a use heat quantity qi of each household H1, H2, H3 calculated based on a water inflow temperature to the hot water supply system and a hot water delivery temperature and a hot water delivery amount from the water heaters B and a total use heat quantity Q of the whole households H1, H2, H3 obtained by totaling up the calculated use heat quantity qi of each household H1, H2, H3, a use heat quantity ratio qi/Q of each household H1, H2, H3 with respect to the total use heat quantity is calculated. A product of the use heat quantity ratio of each household H1, H2, H3 and the uel-electric power use amount G of the whole households H1, H2, H3 is defined as the fuel-electric power actual use amount gi of each household H1, H2, H3.;COPYRIGHT: (C)2010,JPO&INPIT
