Heat storage system

Japanese Patent JP6132015

B2

A heat storage system is provided that comprises a heat storage material having a higher specific gravity in a solid phase than in a liquid phase; a heat storage tank for containing the heat storage material; a cooling side heat exchanger arranged at an upper section inside the heat storage tank and for cooling the heat storage material; a heating side heat exchanger arranged at a lower section inside the heat storage tank and for heating the heat storage material; a wall surface heater for heating a side wall of the heat storage tank; and a solid phase exfoliation unit for allowing the heat storage material, which is cooled by the cooling side heat exchanger and becomes the solid phase, to exfoliate from the cooling side heat exchanger, wherein the solid phase exfoliation unit comprises a solid piece which is added to the heat storage material for colliding with the cooling side heat exchanger due to a flow of the heat storage material in the liquid phase, and allowing the heat storage material, which becomes the solid phase, to exfoliate from the cooling side heat exchanger.
