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.
