摘　　要：系统地总结和分析了流态冰制取技术的研究现状和进展.在此基础上,提出并详细介绍了2类新型流态冰制取方法:溴化锂吸收式低压制冰和与溶液除湿相结合的流态冰制取方法.2类新方法都能利用温度为100℃左右的低位热源作为驱动能源,并通过溶液吸湿制造低压环境.相比传统方法,节省了大量电能.对新方法进行分析总结后,提出了溶液深度除湿蒸发冷冻预冷流态冰制取方法.建立了溶液深度除湿蒸发冷冻预冷实验装置,并进行了实验初探.结果表明,当空气含湿量被降低到3 g/kg时,该装置能有效地制取0℃左右的空气和冷冻水.实验验证了该系统的可行性,并对其优化提供了数据支持.The research actualities and developments of ice slurry producing technologies were re-viewed and analyzed systematically.Two kinds of novel ice slurry producing systems,lithium-bro-mide absorption low-pressure system and the system combined with liquid dehumidification process, were proposed.Both of these two methods can utilize a heat source around 100 ℃ as the driving en-ergy,and create a low vapor pressure environment by using a moisture absorption solution.Com-pared with the conventional systems,the two new methods can alleviate the burden on electric power and raise the efficiency.Then an ice slurry producing system assisted by a deep liquid dehumidifica-tion process and an evaporative pre-cooling process was proposed.Moreover,a testing system was established,and tentative experimental study was carried out.The experiment results show that when the air is dehumidified to 3 g /kg,the air and chilled water around 0 ℃ can be produced effectively. The experiment validates the feasibility of the novel ice slurry producing system and lays the founda-tion for the system optimization.
