Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration and cold storage, and in particular to an anti-blocking supercooling method dynamic ice slurry cold storage system. Background Art

[0002] As the proportion of renewable energy in the power grid gradually increases, the importance of energy storage technology becomes increasingly prominent. As a phase change storage technology, ice storage has become a key means of peak load shaving in summer due to its significant phase change potential. Dynamic ice storage, especially dynamic ice slurry storage generated by supercooling method, achieves the decoupling of heat exchange and phase change process in time and space, and has significant advantages. The generated ice slurry is in slurry form, and the ice crystal particles are usually no more than 1 mm, with good fluidity and rapid release of cold energy.

[0003] Since supercooled water is in a metastable state, achieving a continuous, efficient and reliable supercooled water ice slurry process requires precise control of its formation and release process. First, it is necessary to ensure that the water in the supercooler always remains in a supercooled state without freezing, which requires strict regulation of the operating conditions of the supercooler. Secondly, after the supercooled water enters the ice storage container, it needs to be released from supercooling and crystallized under appropriate conditions to form ice slurry. In addition, it is necessary to effectively prevent the ice crystals formed in the ice storage container from flowing back to the supercooler to avoid causing the supercooling state of the supercooled water to be released, resulting in ice blockage.

[0004] This series of operations is complex and has high requirements on the system. Therefore, the supercooling method dynamic ice slurry cold storage technology is prone to problems such as low ice slurry conversion efficiency, poor system reliability, and easy ice blockage in practical applications. Therefore, improving the efficiency and reliability of the supercooled water ice slurry process has become an important issue that needs to be solved in this field. Utility Model Content
