ある。The present invention has been devised in view of such circumstances, and a problem to be solved is to solve the above-mentioned problems of the conventional heat storage tank. However, in particular, it is a regenerative heat storage medium that is harder to warm than water (harder to cool than water) and that can store latent heat and release heat at a plurality of predetermined temperatures based on a phase transition between a solid phase and a liquid phase. It can be used as a heat storage tank for cooling and also as a heat storage tank for heating by using it as a heat storage medium that has a larger latent heat amount than conventional products and hardly causes a supercooling phenomenon, and has complicated piping and switching valves. It is an object of the present invention to provide a heat storage tank having features such as no need to dispose, a small occupied space, few restrictions on installation, a high degree of freedom in designing and manufacturing, and a low cost.
