An Evaporative Style for Dynamic Ice-slurry producingwith Super-cooled water

摘要

Ice-slurry is an ideal form of ice product for ice-storage, which is an effective measure to save energy. The conventional producing method using super-cooled water suffers the troubles of instability and heavy dependence on electronic power. We propose a novel method to improve that: spraying water is super-cooled by evaporating in a chamber where the air is of low humidity and low wet bulb temperature; a refrigeration cycle and an inlaid liquid-dehumidifying unit are adopted to recover the air to run the cycle; the rejected heat from the condenser is used to drive the liquid dehumidifying unit. System and performance analysis were made. The results indicate that compared to the conventional super-cooled water system, this new system could avoid the ice block, and shoulder off the heavy dependence on the electric power while raise the efficiency by a maximum value of 98% under certain conditions.
