冰蓄冷是一种很有潜力的空调节能方法。冰浆是一种理想的蓄冰材料。传统的利用过冷水制备冰浆的方法存在冰块不稳定的问题，并且严重依赖于电力。针对这一现状，提出了一种新型的利用内部废热的冰浆制备系统。该系统由两个主要过程组成：蒸发过冷过程和液体过冷过程。本文对这两个过程进行了理论和实验研究。对蒸发过冷过程及整个系统的性能进行了仿真分析。对这两种工艺进行了实验研究。理论分析结果与实验结果吻合较好。与传统系统相比，该系统可以减轻电力负荷，提高效率。这些改进主要归功于系统本身产生的内部废热的再利用。
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.
