PURPOSE:To improve the energy-saving effect by a method wherein the heat of solidification liberated at the phase change from liquid to solid and the heat of fusion absorbed at the phase change from solid to liquid of straight-chain alpha olefin sealed as medium within a spherical shell are put to good use. CONSTITUTION:The heat accumulating body A consists of the spherical shell 1 and straight-chain alpha olefin with its melting point lying between -24-80 deg.C sealed within the spherical shell 1 as heat transfer medium. If the body A is intended to be used, for example, as building material parts, a large number of the bodies A are packed tightly between concrete walls 5 and formed as one body product together with the concrete walls 5 at the excecution of the concrete walls 5. As a result, the heat insulating effect, heat accumulating effect and heat shock absorbing effect of the concrete walls 5 is remarkably increased, resulting in enabling to sharply economize energy consumption at air-condition or the like. |
