より回収利用する。When the latent heat storage material 4 is heated by a heat medium from outside the latent heat storage material 3, the temperature of the latent heat storage material 4 rises, reaches a melting point, and is melted. When the heating by the heat medium is completed after the latent heat storage material 4 is completely melted, the heat transfer from the high temperature heat storage tank 1 to the surrounding environment of the low temperature heat storage tank 1 causes the heat storage tank 1, that is, the latent heat storage material 4 to be heated. The temperature gradually decreases. The temperature of the latent heat storage material 4 eventually reaches the melting point, but solidification does not immediately start due to the supercooling phenomenon. The temperature continues to drop further and remains liquid until the solidification onset temperature below the melting point.
In this operation, it is necessary that the latent heat storage material 4 does not fall below the solidification start temperature, and control is performed so that the latent heat storage material 4 does not reach the solidification start temperature. When taking out the stored heat, if the latent heat storage material in the supercooled state is caused to solidify, the supercooled state is broken and solidification occurs, and at that time, the latent heat is released. The latent heat generated in this manner is recovered and used by performing a heat exchange operation with a heat medium.

材４を加熱し、融解させる。In the present invention, the step of heating (heat storage) the latent heat storage material, the step of storing heat, and the step of recovering heat (release of heat) from the latent heat storage material are sequentially performed. In the heat storage step, a region A occupying most of the heat storage tank and a region B occupying a small portion of the heat storage tank are formed by using the heat exchange means.
Then, a heat medium having a temperature equal to or higher than the melting point of the latent heat storage material is caused to flow in and flow through, thereby heating the latent heat storage material in the latent heat storage material. The specific operation is as follows. Opening / closing means (valve) and driving means (pump) for specifying the path are installed in this passage. This route is
It is as follows. Closing the opening / closing means (valves) 8, 11;
The opening and closing means (valves) 9 and 10 are opened, and the heat medium means (pump) 12 is operated. Using a heat medium having a temperature equal to or higher than the melting start temperature of the latent heat storage material 4, the latent heat storage material 4 is heated by circulating in the order of the communication pipe b → the area B → the communication pipe d → the area A → the communication pipe a, Let melt.

As long as the temperature of the latent heat storage material is kept higher than the temperature at which solidification starts (solidification start temperature), this supercooled state is maintained and heat is preserved. Since the shape of the heat storage tank 1 and the heat insulating material constituting the heat storage tank 1 are designed so that the latent heat storage material 4 does not fall below the solidification start temperature during the storage period, the temperature of the latent heat storage material 4 falls below the melting point, It approaches the solidification onset temperature, but begins to solidify within the storage period and does not crystallize.

ｃの経路で循環させる。In the heat recovery process, the heat exchange means is operated to set the heat medium to a temperature lower than the solidification start temperature of the latent heat storage material 4.
By moving the heat medium cooled by the heat exchange means below the solidification start temperature of the latent heat storage material 4 in the region B occupying a small portion, crystals are generated, and the crystals are used as nuclei (to induce solidification). In this way, the entire latent heat storage element is solidified to generate heat of fusion. The specific operation is as follows. The area A occupying the majority and the area B occupying a small part are separated by a separator. Therefore, the heat medium does not flow into the region A that occupies most of the heat medium. The heat medium injected only into the area B occupying a small area can cool only the latent heat storage material existing in the area B occupying the small area without affecting the area A occupying the most area. The latent heat storage element is partitioned by a separator having openings, but a very small crystal caused by the induction of solidification generated in the area B occupying a small area becomes a nucleus, and the crystal grows. To the latent heat storage material of the latent heat storage body existing in the area occupying the area. When the solidification is started, the supercooled state is broken, the temperature of the latent heat storage material rises to the melting point, and the generated heat is recovered by the heat medium. Induction of coagulation in the process of releasing heat is performed by the following operation. Opening / closing means (valves) and heat medium driving means (pumps) are provided in the path of this step. Open the opening / closing means (valves 8, 10) and open / close the opening / closing means (valves 9, 1).
1) is closed, and the heat medium driving means (pump 12) is operated. The heat medium having a temperature lower than the solidification start point by the heat exchange means 5 is circulated through the communication pipe b → the area B occupying a small portion → the communication pipe c.

熱利用される。In this manner, the solidification is induced by lowering the temperature of a part (region B occupying a small part) of the latent heat storage material 4 to the temperature at which solidification starts. The remaining latent heat storage material in the region A, which occupies the most part, has the fine crystals generated as described above serving as nuclei even if the temperature does not drop to the solidification start temperature, and the entire latent heat storage material 4 is crystallized. Coagulation occurs due to ripples in movement. When the solidification is started, the temperature of the heat storage material rises to or near the melting point due to the stored heat of fusion. Next, the opening and closing means (valves 8 and 10) are closed, the opening and closing means (valves 9 and 11) are opened, and the heating medium driving means (pump 12) is operated to flow the heating medium. The heat medium flows through the path of the communication pipe b → the area B occupying a small portion → the communication pipe d → the area A occupying the majority → the communication pipe a, so that the temperature of the latent heat storage material 4 becomes a melting point or a temperature close to the melting point. The recovered heat is recovered by a heat carrier. The recovered heat is passed to the heat utilization facility 6 and is used by heat exchange.
