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.
