Abstract

Abstract: Icing characteristic is important for refrigeration,freezing desalination and chemical engineering. A new freezing method is proposed in this paper,which is driven by humidity difference in 0℃ environment.The evaporation-refrigeration of liquor driven by absolute humidity difference in zero centigrade was studied.Based on heat and mass balance,an unsteady-state thermodynamic model was established with movement characteristic of icing on the surface of liquor,which could simulate icing development under different conditions.The effects of absolute humidity difference,airflow velocity and mass diffusion coefficient on icing development were analyzed.The results indicate that above factors have evident effects on the liquor evaporation-refrigeration.The model and results will provide a theoretical basis and guidance for liquor evaporation-refrigeration driven by absolute humidity difference and its applications.

Key words: evaporation-refrigeration, icing, humidity difference

摘要： 针对湿度(绝对湿度)差驱动下溶液的蒸发冷冻过程进行了分析研究,在热质平衡理论的基础上,考虑溶液表面冰体的形面变化特征,建立了蒸发冷冻过程中溶液表面冰体生长的热力学非稳态模型,分析了不同蒸发冷冻时刻,气-液界面间湿度(绝对湿度)差、气流速度以及气-液界面间质扩散对溶液表面冰体发展分布的影响,研究表明湿度(绝对湿度)差、气流速度和质扩散系数对溶液的蒸发冷冻作用明显。该理论模型及研究结果为强化湿度差驱动下溶液的蒸发冷冻及工程应用提供了理论指导和依据。
