[0017] 1. The cold or hot water resources stored in the utility model can have multiple sources, and the storage of cold or hot water resources can be achieved through the complementarity of multiple sources. For example, the stored hot water resources can be surface water. For example, natural gas becomes liquid at the condensation point of -161.5℃, which is convenient for transportation and storage, but needs to be gasified when used. River water can be stored as hot water resources to gasify natural gas; the stored hot water resources can also come from solar hot water, geothermal exchange hot water, sewage exchange hot water, petrochemical steel and other traditional industrial production cooling exchange hot water resources, etc. The stored cold water resources can be surface water, and can also be natural ice and snow cold water in winter and spring, cold water after LNG gasification completes heat exchange, and cold water resources remaining in the cold chain storage and transportation center station.

[0019] 3. The energy storage system in the present invention is a new way to store clean energy (conventionally in the form of electricity storage). At present, a lot of electricity is abandoned during low-power consumption or unstable electricity such as wind power is mainly stored and regulated in the form of pumped storage power stations, air compression energy storage power stations, batteries, etc., and a lot of electricity is lost in the process; while the energy storage form in the present invention is to use surface water as a carrier to store, regulate, and exchange cold or heat, so that the surface water is heated or cooled and stored, and then it will be directly used according to demand. In this way, unstable electricity or waste heat can be converted into stable water cold and heat resources for temporary storage and reuse.

[0020] 4. The energy is well complementary and has various complementary forms, including cold and hot resources of industrial cooling waste water, solar water resources, geothermal resources, cold and hot resources caused by the temperature difference between day and night, waste heat resources of urban sewage temperature difference, cold and hot resources produced during low electricity consumption, etc., which can complement each other and be temporarily stored and utilized in the form of cold and hot water resources.

[0021] 5. Reduce the occupation of surface water resources.

Gasification with surface water is the safest and most economical; the utility model is used to gasify the LNG, because the water body cooled by the gasifier can be used again after heating, solar hot water heating and other measures, thereby saving more water resources in nature from surface water sources. Studies have shown that the amount of water saved can reach more than 50%.

[0022] 6. The utility model has a wide range of uses. The utility model can be used in river water source air conditioning in urban buildings, heat dissipation in data storage and computing centers, gasified LNG (liquefied natural gas), industrial cooling water in thermal power plants, steel mills, agricultural breeding and other industries.

The outlet of the circulating water body temperature recovery system 6 is connected to the water inlet of the temperature control valve. The temperature control valve 61 senses the water temperature. In the cooling mode, When the temperature of the water flowing out of the circulating water temperature recovery system 6 is above the set temperature threshold, the valve core of the temperature-controlled diverter valve rotates to block the pipeline leading to the cold water source production and manufacturing system 52, and the water flows to the pipeline of the waste water discharge system 7 and is discharged into the river. When the temperature of the water flowing out of the circulating water temperature recovery system 6 is below the set temperature threshold, the valve core of the temperature-controlled diverter valve rotates to block the pipeline leading to the waste water discharge system 7, and the water flows to the water inlet of the cold water source production and manufacturing system 52, thereby realizing the recycling of water.
