Description of the Related Art A latent heat storage material has a high heat storage density and a constant phase change temperature as compared with a sensible heat storage material, and has been put to practical use taking advantage of the advantage that the heat extraction temperature is stable. . Ice, sodium sulfate decahydrate, calcium chloride hexahydrate, sodium acetate trihydrate and the like are known as latent heat storage materials. However, the phase change temperature of these latent heat storage materials is relatively low, and a high phase change temperature of about 90 to 190 ° C. is desired. As a heat storage material for hot water supply and waste heat utilization of boilers and utilization of solar energy, Is inappropriate.

解決すべき問題点が多い。Erythritol has a large heat storage capacity, excellent thermal stability and is non-toxic, but its phase change temperature is constant due to the substance. Therefore, in order to use sugar alcohol as a heat storage material, it is required to adjust the phase change temperature to be suitable for a heat storage system. At the 16th Japan Thermophysical Symposium (1995, P221), it was reported that the addition of pentaerythritol, pentaglycerin and neopentyl glycol to erythritol reduced the phase change temperature of erythritol to around 100 ° C. However, there are many problems to be solved, such as the double peak of coexistence of two phases and the decrease in heat storage to less than half.

Usually, it is 1 to 30% by weight, preferably 3 to 20% by weight. When the content of the melting point modifier is more than 30% by weight, the content of the sugar alcohol in the heat storage material composition decreases and the amount of heat storage decreases, while when the content is less than 1% by weight, the effect of lowering the melting point is obtained.

熱伝達効率が高いという利点がある。Examples of the method of using the heat storage material composition of the present invention include a capsule type in which the heat storage container is filled with the heat storage material composition and a microcapsule type in which a heat storage container is not required. The capsule type is obtained by injecting the heat storage material composition into a heat storage container such as a capsule and sealing the heat storage container. The material of the capsule may be any material that does not deform or melt in the operating temperature range, and examples thereof include metals such as stainless steel and aluminum, glass, and engineering plastics such as polycarbonate. The shape of the capsule is not particularly limited, and examples thereof include a sphere, a plate, a pipe, a constricted cylinder, a twin sphere, and a corrugated plate, and are appropriately selected depending on the application. The microcapsule type is a product in which fine heat storage material particles or their aggregates are covered with a coating such as a resin that does not melt and deteriorate in the operating temperature range.
There is an advantage that heat transfer efficiency is high.
