決が必要である。However, when the heat cycle of melting heat storage and solidification heat release is repeated over a long period of time, crystals of sodium acetate anhydride gradually precipitate in the system. The production of the anhydrous salt itself does not interfere with the heat cycle, but when it gradually increases in large quantities and begins to settle and accumulate at the bottom of the system, a so-called phase separation phenomenon occurs, making efficient heat extraction impossible. is necessary.

し未発明を完成するに到った。However, the inventors of the present invention have conducted extensive research to solve this problem, and have found that a heat storage material composition consisting of sodium acetate pentahydrate and carboxylic acid undergoes a heat cycle of heating and releasing heat over a long period of time. However, the precipitation of sodium acetate anhydride and phase separation due to precipitation 11 do not occur at all, allowing for efficient heat exchange, and the addition of carboxylic acid slightly lowers the condensation point of sodium acetate trihydrate, so it is relatively The inventors discovered that even if an inexpensive heat collector is used, remarkable effects such as being able to efficiently obtain a predetermined amount of heat can be achieved, and the invention has been completed.
