Title:
AIR-CONDITIONING HOT-WATER-SUPPLYING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2011/108073
Kind Code:
A1
Abstract:
In order to have increased overall efficiency, the disclosed air-conditioning hot-water-supplying system is provided with a hot-water-supply assist means (80) for using heat generated through a heating operation for a hot-water-supply operation. A control device (1a) is provided with: a means (S10) for estimating the current air-conditioning load; a means (S11) for estimating current air-conditioning power consumption; a means (S12) for estimating the current hot-water-supplying load; a means (S13) for estimating current hot-water-supplying power consumption; a means (S16) for provisionally determining the estimated air-conditioning load; a (S18) means for adding a predetermined value to the provisionally determined air-conditioning load, calculating a new air-conditioning load; a means (S18) for calculating air-conditioning power consumption on the basis of the new air-conditioning load; a means (S19) for calculating the hot-water-supplying load on the basis of the new air-conditioning load; a means (S20) for calculating the hot-water-supplying power consumption on the basis of the new air-conditioning load; a means (S22) for comparing total power consumption values; and an assist control means that controls the operation of the hot-water assist means in a manner so as to approach the new air-conditioning load in the case (Yes in S22) where the total power consumption values decrease.
