| Zusammenfassung: | In a latent heat storage material composition prepared by mixture of a latent heat storage material with an additive that adjusts the physical properties of the latent heat storage material, the latent heat storage material includes an inorganic salt hydrate containing nw (2≤nw) molecules of hydration water. The additive is a melting point modifier for adjusting the melting point of the latent heat storage material and is a substance belonging to a sugar alcohol, and is a substance having the physical property of producing negative dissolution heat upon dissolution in hydration water contained in the latent heat storage material. In a whole amount of the latent heat storage material composition, the substance belonging to a sugar alcohol has a concentration that satisfies formulae (1) and (2) per 1 mole of water of hydration of the latent heat storage material. Formula (2): 0.01≤xs≤1. |
