Ice slurry that is a mixture of fine ice crystals and liquid water has been utilized in the ice storage system due to its good flow-ability and large latent heat of fusion. For ice slurry production techniques, there are presently a number of commercially available ice slurry generators. (e.g. Supercooled slurry ice generator, Scraper type generator, and Vacuum type generator etc.). In this study, an ice slurry sequential generating method was proposed. This method is based on the freezing-point depression phenomenon of the aqueous solution, which is maintained at a high-pressure condition. A low concentration NaCl aqueous solution was used as the testing fluid. As a result, we developed the ice slurry sequential generator on the basis of the pressure shift freezing method. Moreover, the experimental results showed that the characteristics of the ice slurry were closely related to the pressure and the initial temperature of the testing fluid.
