<P>PROBLEM TO BE SOLVED: To downsize a hot water storage tank which forms thermal stratification therein and sufficiently utilizes a heat storage capacity of a latent heat storage material. <P>SOLUTION: A latent heat storing hot water storage tank includes a hot water storage tank 2, a water supply port 3 for supplying water under pressure to the bottom of the hot water storage tank 2, a hot water discharge port 4 for discharging the hot temperature water at the top of the hot water storage tank 2 to a hot water discharge place, and circulation pipes 5a, 5b for draining the low temperature water at the bottom of the hot water storage tank and heating and returning that water to the top of the tank. In the hot water tank, a plurality of latent heat storing materials 8a, 8b having different transition temperatures from high temperature to low temperature are filled in the hot water storage tank 2 in layers toward the water supply port from the hot water discharge port, and the water flowing in the hot water storage tank between the hot water discharge port and the water supply port is heat exchangeable with the latent heat storage materials 8a, 8b. <P>COPYRIGHT: (C)2012,JPO&INPIT |
