摘　　要：该文旨在比较LiBr和LiCl溶液的再生传热传质性能。通过搭建的溶液再生实验台,分别采用LiBr和LiCl溶液实验测试了一系列在溶液调湿空调的再生器中常见的工况;整理再生实验数据,针对评价传热传质性能的指标——再生量,拟和了经验公式,通过经验公式可以计算出实验范围内任意工况下的传热传质性能;再生量是衡量传热传质性能的最直观指标,进口参数等效时,LiBr和LiCl溶液的再生量差别很小,在进口溶液浓度较低(LiBr溶液在40%～43%)时,LiCl溶液的再生量较高;而进口溶液浓度较高(LiBr溶液在48%～50%)时,LiBr溶液的再生量略高。The regenerating capability of LiBr and LiCl solution was compared in the paper.A series offamiliar working conditions in regenerator adopting LiBr and LiCl solutions separately were tested.Experience formulas of regenerating mass per second which was guideline to evaluate heat and mass transfer performance were educed according to experience data.The difference of regenerating mass per second between LiBr and LiCl solution is small in equal condition.In lower concentration（LiBr is 40%-43%）,LiCl solution has higher regenerating mass,while in higher concentration（LiBr is 48%-50%）,LiBr solution has higher regenerating mass per second.
