化学蓄熱システムが研究開発されている。[East 11] As a means of effectively utilizing intermittent energy such as solar heat and industrial waste heat, or late-night electricity where the time between supply and demand is different, there are various explicit heat storage systems and solid materials that store energy in the form of heat. Latent heat storage systems or chemical heat storage systems that store heat at a constant temperature by utilizing latent heat during a phase change between a phase and a liquid phase are being researched and developed.

熱蓄熱材として優れている。Referring to latent heat storage systems, substances, depending on their chemical composition, can absorb heat and change from a solid to a liquid at a certain temperature under a certain pressure, and change from a liquid to a solid by releasing heat. The amount of heat absorbed or released due to this phase change is called latent heat, but the latent heat per unit mass is large, in other words, the heat storage density is high, and the phase change temperature, that is, the heat storage temperature, is equal to the temperature of the fluid used. On the other hand, those with moderately high values are excellent as latent heat storage materials.

可能となる。Examples of low-temperature latent heat storage materials include chlorides, some organic substances, their eutectics, and clathrate swollen hydrates, and examples of high-temperature materials include metals and various molten salts. As the molten salt, for example, a caustic soda-based eutectic mixed salt is suitable at temperatures below 450°C. When this is used to store nighttime electricity or critical energy that has traditionally been difficult to use as heat, compared to conventional methods that heat water stored in a tank to raise its temperature and store it as heat. Since the temperature is high and the amount of heat stored per unit weight can be increased, it is possible to downsize the device.

安全に、必要な量を取出すことが困難である。However, when the purpose is to obtain hot water or steam at a temperature of 100°C or slightly higher, for example, a heat storage tank using a eutectic mixed salt of soda carbonate and caustic soda as a heat storage material is used. When water is passed through the heat transfer tubes, the high heat storage temperature has a negative effect on the temperature difference between the water and the heat storage material, so the water in the heat transfer tubes instantly evaporates, and the pressure causes the device to With this device, it is difficult to easily and safely extract a required amount of fluid at a desired temperature from a heat storage material in which heat is stored in a high density.
