型になるという欠点があった。As shown in Fig. 1, the conventional thermal storage type hot water supply system stores solar heat absorbed by a heat collector 1 in a heat storage tank 2, and uses this heat for hot water supply (when there are two phases (- indicates the heater 3 is used as an auxiliary heat source). It is used by heating to a predetermined temperature, and consists of a heat collection channel 4 that collects solar heat and a hot water supply channel 5.The sensible heat of water is used for the heat storage agent 6, but the heat storage density is small. The drawback was that the heat storage tank was large.

には使用できないという欠点があった。On the other hand, conventional heat storage systems have utilized latent heat storage agents that utilize phase change latent heat of solid-liquid to reduce the size of heat storage tanks. This has the advantage of higher heat storage density than the sensible heat type. However, latent heat storage agents that utilize the latent heat of solid-liquid phase change are generally made of organic materials such as paraffin or inorganic water salts such as sodium sulfate, and are sealed in airtight containers to avoid contamination with hot water supply water. However, if this container is damaged (2), there is a risk that the latent heat storage agent may be mixed into the supplied water ('), so it cannot be used for hot water supply.

う利点を有する。The present invention relates to a hot water supply system using a latent heat storage agent that utilizes phase change latent heat of solid-liquid. This provides a system that does not mix into the hot water even if the water is damaged, and has the advantage of enabling a latent heat storage type hot water system.

ある。In addition, with the configuration shown in FIG. 2, even if the closed container of the latent heat storage agent 11 is damaged, the heat storage agent 11 will only be mixed into the heating medium 18 in the heat collection flow path, and the hot water 14 will be separated from the partition wall. 16, it is possible to prevent water from flowing into the hot water supply 14, which has the advantage that it can be used as a heat storage system for hot water supply.
