PURPOSE:To store and release heat, utilizing melting latent heat and evaporating latent heat by directly bringing a heat storing element into contact with a heat medium to form boundary face, allowing the boundary face to flow, vibrating the boundary face and mixing both phases when heat is stored to carry out heat exchange and solidifying part of the heat storing element. CONSTITUTION:A heat storing element in which solid liquid phase is changed is directly brought into contact with a heat medium having difference of specific gravity to the heat storing element and flow point temperature lower than solid-producing temperature of the above-mentioned heat storing element to form a boundary face. When heat is stored, the above-mentioned boundary face is allowed to flow and vibrated and/or both element phases are mixed and heat exchanging layer is formed to carry out heat exchange and part of the above-mentioned heat storing element is solidified and separated from the liquid phase of heat storing element. Thereby storage and release of cool heat having <=15 deg.C temperature are carried out utilizing latent heat using the heat storing element and heat medium. |
