摘要/Abstract

摘要： 在顺流型平板降膜热质交换测试装置上对氯化锂水溶液与湿空气除湿、再生性能进行了实验研究,结合NTU-Le模型,着眼于湿空气与溶液耦合热质交换特性,获取了顺流条件下不同空气流量、溶液流量、溶液温度工况的耦合传热传质系数随运行参数的变化情况。研究结果为相关过程模型验证提供可靠数据,同时也为相关设备性能分析与计算提供重要基础数据。

Abstract: Experiments on liquid desiccant dehumidification and regeneration were performed to investigate the characteristics of heat and mass transfer between aqueous solution of lithium chloride and air with parallel flow.Based on the NTU-Le model,the coupled heat and mass transfer coefficients were obtained according to the experimental results,and the effects of mass flow rates of air and liquid desiccant and liquid desiccant temperature were analyzed.The results provide reliable data for the related model validation and equipment performance analysis and calculation.

Key words: liquid desiccant dehumidification/regeneration, parallel flow, heat and mass transfer
