A novel ice slurry producing system: Producing ice by utilizing inner waste heat

Ice storage is a potential energy saving method for air conditioning systems. An ice slurry is an ideal material for ice storage. The conventional ice slurry producing method using supercooled water suffers from the instability of ice block and depends heavily on electric power. A novel ice slurry producing system utilizing inner waste heat was proposed to improve this situation. This system consists of two major processes: an evaporative supercooling process and a liquid dehumidification process. Both theoretical and experimental works are presented about these two processes. Simulation analysis has been made on the evaporative supercooling process and the performance of the whole system. Experiments were performed about the two processes. The theoretical conclusion agrees well with the experimental results. Compared with the conventional system, this new system can alleviate the burden on electric power and raise the efficiency. Those improvements are essentially attributed to the reutilization of the inner waste heat generated from the system itself.
