PURPOSE:To increase heat accumulating efficiency by a method wherein a latent heat accumulating material is sealed in a heat accumulating capsule accommodating metallic fine wires and the capsule, sealing the heat accumulating material of high melting point, is arranged at the inside of the capsule sealing the heat accumulating material of low melting point. CONSTITUTION:The heat accumulating vessel 1 accommodates the heat accumulating capsules 2, 3, 4, sealing the latent heat accumulating material, and is partitioned by partitioning walls 5, 6 so that the heat accumulating chambers 7, 8, 9 become concentric. The latent heat accumulating materials are sealed into the heat accumulating capsule so that the metallic small vessel 14 is filled with the metallic fine wires 15 and a space between the metallic fine wires is filled with the latent heat accumulating material. In case heat is accumulated, heated heat medium flows into the heat accumulating chamber 7 through a heat medium pipe 12, the heat thereof is exchanged with the latent heat accumulating material in the capsule 4 and accumulates the heat in the form of melting latent heat of the heat accumulating material, thereafter, it flows into the chamber 8, the heat thereof is exchanged with the medium temperature heat accumulating material in the capsule 3 to melt the same material or rise the temperature in case it is in a molten condition, then, flows into the chamber 9 accommodating the capsule 2 sealing the low-temperature material and accumulates heat here, therafter, flows out of the heat medium pipe 13. According to this method, the heat accumulating efficiency is improved and heat dissipating speed may be increased. |
