Abstract:A novel vacuum ice slurry producing system with jet-pumps was proposed to deal with the problems of high energy consumption and ice blockage. In this novel system, one steam driven by a jet-pump was used to create vacuum in a hermetic vessel where water was sprayed through a nozzle to produce ice slurry, while the other steam was used to provide enough cold energy to make the left vapor in the hermetic vessel condense. Mathematical models of this novel system were established and theoretical simulation on the performance characteristics was also implemented based on the MATLAB program. Results show that the novel system is feasible and practicable, and the system performance is affected by many factors, such as the temperature of the generators, condensing temperature, evaporation temperature, and the cooling load of the refrigerator sub-system. The findings are helpful to improve the performance of ice slurry producing system.
