在平板降膜溶液除湿/再生实验平台上，以 LiCl 水溶液作为除湿溶液，实验研究了空气、溶液的入口参数对空气出口参数的影响，并根据实验数据得到了耦合传热传质系数的关联式，为NTU-Le模型提供了重要的数据支持，同时将实验数据与NTU-Le传热传质模型计算所得的数据进行比较，来验证NTU-Le传热传质模型在平板降膜溶液除湿/再生过程中的适用性和准确度。结果显示：实验数据和模型计算值之间的偏差均在10%以内，表示NTU-Le模型适用于平板降膜溶液除湿/再生过程。

To investigate the heat and mass transfer performance of liquid desiccant dehumidification/regeneration in falling-film plates, experiments were performed in the dehumidifier and regenerator using LiCl solution as the liquid desiccant. Effects of inlet air and solution parameters on their outlet parameters were examined experimentally. Empirical correlations coupling heat and mass transfer coefficients were presented, and the calculation results from NTU-Le heat and mass transfer model was compared with experimental data to verify the accuracy and suitability of the model. The results show that the error between simulation results and experimental data is within 10%, so that the NTU-Le model is suitable for the liquid desiccant dehumidification and regeneration in falling-film plates. The experimental results also provide reliable data for further analysis of heat and mass transfer performance between air and desiccant.
