ある。2. Description of the Related Art Heat is stored using inexpensive nighttime electricity,
Various heat recovery systems have been considered in order to recover exhaust heat and reuse it, or to store heat for emergency backup of heat. The heat storage tank plays a major role as a means for storing the heat recovered by such a heat recovery system. This heat storage tank is roughly classified into a latent heat storage type and a sensible heat storage type. In the latent heat storage type heat storage tank, one that freezes water and stores heat with the latent heat of the ice,
There is one that fills water with CFCs and mixes them by stirring well and generates so-called clathrate so-called clathrate and stores heat with latent heat of the clathrate. For example, there is one that cools to 10 ° C. to 5 ° C. or makes warm water at 40 ° C. to 50 ° C. to store heat.

い等の問題がある。However, each of the heat storage tanks described above has some advantages but many drawbacks.
For example, a latent heat storage type heat storage tank using ice can store heat at a high density, but since it must be kept at a low temperature of 0 ° C or lower in order to use ordinary water to make ice, a heat pump as a heat source device for cooling There is a problem that the efficiency of is low. Further, in the latent heat storage type heat storage tank based on the clathrate, since it is possible to store heat at a relatively high temperature of about 5 to 8 ° C. and high density, it is possible to reduce the space for heat storage and to improve the operating efficiency of the heat source device. However, there is a problem that it takes time to collect CFCs. And
Although the initial cost can be reduced in the sensible heat storage type heat storage tank using water, there are problems such as maintenance and replacement work against water corrosion and a small heat storage density.
