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。
The simple control equations derived from the one-dimensional coupled heat and mass transfer model are used for numerical simulation. The solution inlet parameters, the air inlet parameters, the solution air flow ratio L / G, the Lewis number Le in the overall heat and mass transfer process, NTU and other factors on the outlet air temperature, moisture content. It is concluded that the solution inlet temperature, the concentration and the solution air flow ratio L / G are the most important influencing factors, which provides a useful idea for designing and improving the liquid desiccant air conditioning system.
