PURPOSE:To enhance heat-exchanging efficiency by transferring a multiplicity of capsules filled with a heat-accumulating material from a first container to a heat- releasing part, causing the capsules there to release thermal energy to an external heat-transmitting medium, and housing the capsules into a second container. CONSTITUTION:A heat accumulator 1 uses capsules filled with a heat-accumulating material, the capsules being, for example, spherical. A multiplicity of the capsules contained in a first container 2 are fed out of the container 2 to a heat-releasing part 4 while being regulated in quantity by a regulator 5, and release thermal energy to a heat-transmitting medium at the part 5. The heat-transmitting medium having had a low temperature deprives the heat-releasing part 4 of heat, thereby being heated to a predetermined temperature, and is sent out to be utilized. The capsules having released the thermal energy are contained into a second container. The heat- accumulating material, which is enclosed in the capsules, can be moved without adhering to wall surfaces of the heat-releasing part even upon solidification thereof through the release of heat. It is therefore possible to recover latent heat at a high rate, and to speedily take off a large quantity of heat by optimizing the quantity of the heat- transmitting medium and the quantity of the capsules fed out. |
