<p><P>PROBLEM TO BE SOLVED: To provide technology capable of quickly stabilizing a hot water supply temperature at a desired temperature in feedback control of a mixing unit. <P>SOLUTION: A hot water supply system comprises: a hot water storage tank; a water supply passage for supplying water to the hot water storage tank; a hot water supply passage for supplying hot water from the hot water storage tank; a bypass passage as a mixing unit for adjusting a temperature by mixing the water in the water supply passage to the hot water in the hot water supply passage, and branched from the water supply passage and joined to the hot water supply passage while bypassing the hot water storage tank; the mixing unit disposed in the bypass passage and comprising a mixing valve; and a controller for adjusting an opening of the mixing valve. In this hot water supply system, the controller decides the increase and decrease of the opening of the mixing valve on the basis of not only a target mixing ratio and a present mixing ratio in the mixing unit but also a hot water supply flow. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
