Abstract：

Regenerator is a crucial component in the liquid desiccant air conditioning system. Establishes a performance testbed for crossflow regenerators and a mathematical model for the heat and mass transfer. Using lithium bromide aqueous solution as liquid desiccant, adopting the total heat transfer rate and enthalpy efficiency to describe the combined heat and mass transfer performance and the moisture removal rate and regenerative efficiency to describe the mass transfer performance of the regenerator, explores the effect of air and desiccant inlet parameters on the regenerator performance by experiment, and compares the result obtained with those of other counterflow configurations previously published. The numerical simulation result obtained by taking the dimensionless mass transfer coefficient as the input parameter of the mathematical model is consistent with the 73 groups of the experimental data and the discrepancies of the enthalpy efficiency and regenerative efficiency are mainly within ±15%.
