摘　　要：利用一维耦合传热传质模型得出的简单控制方程进行数值模拟,全面分析溶液入口参数,空气入口参数,溶液空气流量比L/G,整体传热传质过程的刘易斯数Le,传递单元数NTU等因素对出口空气温度、含湿量的影响。得到溶液入口温度、浓度,溶液空气流量比L/G是最主要影响因素的结论,为设计和改进液体除湿空调系统提供了有益的思路。In this paper,one-dimensional model is used to describe coupled heat and mass transfer processes in the packed bed liquid desiccant dehumidifier.Numerical simulation has been implemented with derivative ordinary control equations.The influencing factors for outlet air parameters are:the inlet parameters of solution and air(such as temperature and concentration),flow rates ratio L/G,Lewis factor,number of transfer units(NTU). The results show that the most important factors are:the inlet temperature and concentration of solution,number of transfer units(NTU).
