Abstract:
1. A method of manufacturing a heat storage material containing heat storage capsules comprising a phase change material that at least one of absorbs latent heat or discharges latent heat in accordance with change in temperature, the phase change material being charged in outer shells of the heat storage capsules, the method comprising the steps of: binding a periphery of mutually contacting portions of a plurality of heat storage capsules with a molding binder, thereby to mold a granular molded heat storage material; coating an outer peripheral surface portion of the granular molded heat storage material with a coating binder to form a coated granular molded heat storage material having a coating layer; and subjecting the coated granular molded heat storage material to a reaction promoting treatment for promoting a polymerization reaction of at least the coating binder in the coating layer, thereby forming said heat storage material.
