摘　　要：冰蓄冷技术是一种有潜力的节能技术,流态冰是实现冰蓄冷的良好选择。利用低含湿量制取流态冰的冰蓄冷系统可以克服现有流态冰制取方法的缺点。系统通过溶液除湿循环降低水蒸气分压力,水滴在此环境中持续蒸发至过冷状态,之后使用传统过冷水法的解冷器获取流态冰。溶液除湿过程与水滴蒸发过冷过程是系统的两个重要组成部分,经过对两个过程的实验研究,结果验证了新系统的可行性并揭示了进一步优化的方法;同时,实验中得到了冰晶颗粒,这也显示了系统的应用前景。Ice storage is a promising technology for energy saving. Ice slurry is favorable material for ice storage. To overcome the short- comings of the present method of ice slurry production, a new ice storage system is developed to produce ice slurry with low humidity. It drives a liquid desiccant cycle to obtain an environment of low water vapor pressure. Droplets keep on evaporating in such an environment and become super-cooled. Then the super-cooled state will be released with a releaser to get ice slurry in the same way of the conventional super-cooled water method. The system mainly consists of two important processes, liquid dehumidification and evaporative super-cooling. These two processes were investigated by experiments. The results prove the feasibility of the new system and expose some method for fu- ture optimization. Meanwhile, Ice slurry was formed in the experiments, which shows a good potential of the system.
