Research status of supercooled water ice making: A review

This review summarizes the theoretical conditions of making fluid ice from supercooled water, the ice making process, and two system forms of making ice from supercooled water. Theoretical conditions include thermodynamic principles and ice nucleus generation mechanism; the ice making process includes the preparation of supercooled water, the release of supercooled state, the separation of ice and water, and the storage of ice crystals; the system forms include direct cooling systems and indirect cooling systems. At the same time, the ice making rate per cycle of supercooled water, the influencing factors of ice blocking and the application scenarios of fluid ice are discussed. Finally, the advantages and disadvantages of making fluid ice from supercooled water are summarized, and future research is made.
