PURPOSE:To make the handling of materials easy and widen their use range by sealing heat storage materials having large heat of fusion and phase change heat into microcapsules. CONSTITUTION:Sealing heat storage materials such as natural wax, petroleum wax, the hydrate of inorganic compound, etc., changing their phases into microcapsules allows the surfaces of those materials to be used as the microcapsules in a solid phase even when the materials are in a liquid phase. Sealing the heat storage materials into fine capsules makes heat absorption and heat radiating area larger and the efficiency of heat storage and heat release is remarkably improved. The heat absorbing and releasing effect of the heat storage materials can be increased by adding metal fine fragments and/or powder into the heat storage materials or containing the metal fine fragments and/or powder in the inside of the capsules. Thereby, the handling of the heat storage materials is made easy and the materials can be used in a wide range such as the interior material of buildings, clothes, etc. |
