| Résumé : | Ice slurry, which is a mixture of fine ice crystals and liquid water, is utilized in ice storage systems owing to its good flowability and large latent heat of fusion. In the present study, a method was developed to generate ice slurry without the deposition of an ice layer on a cooled surface. This method is based on freezing-point depression of the aqueous solution, which is maintained under highpressure conditions. To control the timing for solidification and to generate ice slurry, we investigated the relationships among the pressure, temperature, and concentration of the aqueous solutions. We developed an ice slurry generator based on the new method that controls the pressure and temperature of the aqueous solution. Experimental results showed that the characteristics of the ice slurry generation were closely related to the pressure and initial stage temperature of the test fluid. |
