う問題があった。(Problems to be Solved by the Invention) In the heat storage system described above, during the cold storage operation, the amount of heat held by the vapor evaporated from the concentrated liquid is released to the outside of the system by the cooling water in the process of cooling the diluted liquid. Therefore, the loss is large in terms of heat economy. Further, in order to heat by the heat storage system, the concentrated liquid heat exchanger 1 and the diluted liquid heat exchanger 2 must be replaced with each other and the concentrated liquid tank 3 and the diluted liquid tank 4 must be replaced with each other, which makes the operation complicated. . In addition, if the temperature of the cooling water 12 is high during the cooling operation, the concentration X B2 of the concentrated liquid exceeds the crystal concentration with respect to the temperature T W to crystallize, which causes a problem that the operation cannot be performed.
