<p><P>PROBLEM TO BE SOLVED: To provide a solar hot water supplier for safely supplying hot water, while preventing an overheated hot water supply, without requiring a shutoff valve having a large opening area. <P>SOLUTION: This control method of hot water supply temperature uses a solar hot water supplier 30 comprising: a heat collecting apparatus 1; a hot water storage tank 3 for storing the hot water heated through the heat collecting apparatus 1, and a water-hot water mixing device 14 for diluting the hot water from the hot water storage tank 3 with the water from a feed water branch pipe 11; and a control part 7/8. There are provided another branch pipe 11c bypassed to the lower stream or upper stream of the mixing device 14 from the branch pipe 11, and a shutoff valve 12 in the middle of the branch pipe 11c. The shutoff valve 12 is forcedly opened when a water-hot water mixture temperature TK is higher than a target water-hot water mixture temperature TM by a prescribed temperature to mix water with hot water, closed in detecting a water flow stoppage by a water flow sensor 19. <P>COPYRIGHT: (C)2003,JPO</p> |
