PURPOSE:To prevent the temperature in the interface between a space part and a heat- accumulating material filled part from decreasing, and to improve a heat radiant characteristic, by providing a connecting pipe between the heat radiated space part and the heat-accumulating material filled part, in a solar heat accumulating apparatus for supplying hot-water or for heating rooms, utilizing a heat-accumulating material and a phase transition heat-transferring medium. CONSTITUTION:At the time when heat accumulating performance is finished, the inside of a heat accumulator tank 1 has been filled with the melt of a heat-accumulating material 2 and the saturated steam of a heat-transferring medium 3. Then cooling water is fed into a heat radiating vessel 5 for a space part, the steam in a space part A from the heat-transferring medium 3 is condensed, and it heats the cooling water in the vessel 5. Then the steam pressure in the space part A is decreased, so that the mixed liquid of the melt of heat-accumulating material 2 and the heat-transferring medium 3 is drawn up to the space part A by the intermediary of a connecting pipe 6. In such a manner, convection is smoothly taken place in the melt of heat-accumulating material 2, accordingly, the temperature in the interface C is prevented from lowering. On the other hand, the condensed heat-transferring medium 3 is dripped down to the heat-accumulating material 2 and is evaporated again. With such an arrangement, a heat radiant characteristic can be improved in the titled apparatus. |
