Mass of clathrate hydrate, formation method thereof, heat storage method, heat storage device

摘要

PPROBLEM TO BE SOLVED: To provide a technique useful for establishment of heat storage technique using a clathrate hydrate, overcoming lowliness of heat conductivity of clathrate hydrate as latent heat thermal storage material, enabling much latent heat accumulation and capable of withstanding utilization to actual heat storage air conditioning system, etc., in a block body of the clathrate hydrate produced by heat exchange between an aqueous solution containing a clathrate hydrate-producing substance and a heat sink. PSOLUTION: The block body of clathrate hydrate is obtained by cooling the aqueous solution containing the clathrate hydrate-producing substance. Since the block body of clathrate hydrate has a solidifying point not lower than 0C, the block body is obtained by cooling the aqueous solution to a temperature not higher than an eutectic point of the clathrate hydrate and ice.
