Document Type and Number:
Japanese Patent JP6999030
Kind Code:
B2
Abstract:
There is provided a latent heat storage material that retains the cold insulation capability thereof and is still restrained from supercooling. The latent heat storage material includes: quaternary ammonium ions and first anions that together form a quaternary ammonium salt; water; and calcium carbonate, wherein the quaternary ammonium salt and the water can form a clathrate hydrate, the quaternary ammonium salt and the water have a composition ratio in which the quaternary ammonium salt and the water can at least form the clathrate hydrate, and the calcium carbonate has an addition ratio relative to a mass of an aqueous solution that is the latent heat storage material excluding the calcium carbonate, the addition ratio being higher than a solubility of the calcium carbonate in the aqueous solution at an onset temperature of melting of the aqueous solution that is the latent heat storage material excluding the calcium carbonate.
