Since the ice crystals have a density less than that of water, the ice crystals may be suspended at the upper portion of the inner cavity of the refrigerator 40 after entering the refrigerator 40; when cold energy is needed, the temperature of the water flowing back is higher, the cold energy is absorbed after the water is fully contacted with the ice crystals through upper spraying, and finally the water is discharged out of the refrigerator 40 in a form of frozen water, so that a heat exchanger is not needed, and the refrigerator is economical and reliable, and the heat exchange efficiency is high due to the large contact surface. After the chilled water is supplied with cooling energy, it is determined whether the return flow is required according to the water level in the refrigerator 40.
According to the seawater desalination and ice cold accumulation coupling system provided by the embodiment, the process of condensing and melting seawater desalination water by a decoupling freezing method is performed, desalted ice is used as a cold accumulation medium, and a refrigerating unit can be used for desalting and cold accumulation at the same time, so that the utilization rate of each part of the system can be effectively improved, and the production benefit is improved; the system can be used in combination with renewable energy sources for power generation, and can also be used in the scenes of island, ships, energy micro-nets and the like.
The present invention has been described in detail with reference to the accompanying drawings, but the embodiments of the present invention are not limited to the above embodiments, and those skilled in the art can make various modifications to the present invention according to the prior art, which are all within the scope of the present invention.
