にそのまま系外に排出されている。(Prior Art and Problems to be Solved by the Invention) Generally, in water production plants that produce fresh water from seawater, various methods such as a multi-stage flash method and a freezing method are put into practical use. By the way, the water production plant using the above-mentioned freezing method cools seawater to below the freezing point, freezes the water in the seawater, and then extracts fresh water by melting the ice. However, in current water production plants, the cold energy used for freezing and the concentrated brine produced during freezing are not used for any other purpose and are directly discharged from the system.

因がある。On the other hand, thermal storage type cooling and air conditioning equipment that stores heat using cheap electricity at night and uses it for cooling during the day has begun to attract attention. Studies have begun to consider ice heat storage systems that can store a large amount of heat in a relatively small volume by melting and utilizing this ice. However, in this ice heat storage system where heat is stored simply by ice, the refrigerant temperature needs to be below the freezing point in order to produce ice, which reduces the mechanical efficiency of the refrigerator and increases the amount of refrigerant transported. There are economic impediments such as an increase in power.

A solar pond power generation system has also been developed that uses these temperature differences to cause evaporation, expansion, and condensation of a secondary medium to generate electrical energy. However, since this system utilizes solar heat, it can be fully used in areas with high amounts of solar radiation during the day, but it is necessary to economically form a concentrated brine layer in the solar pond.
