摘　　要：除湿器和再生器是溶液除湿系统的重要传热传质部件。建立了一个测试叉流除湿、再生模块性能的实验台 ,以溴化锂溶液为除湿剂 ,用除湿量、除湿效率和体积传质系数描述除湿效果 ,实验测试了溶液和被处理空气的进口参数对除湿器性能的影响。由实验数据得到的准则关联式 。Establishes a performance test-bed for cross-flow dehumidifiers and cross-flow regenerators which are major components for heat and mass transfer in liquid desiccant air conditioning systems. Selects moisture removal rate, dehumidifier effectiveness and volumetric mass transfer coefficient to describe the mass transfer performance of the dehumidifier and carries out the performance test of a dehumidification module using LiBr solution as liquid desiccant. Proposes the dimensionless mass transfer correlation obtained from the experiment results be used in design of the cross-flow dehumidifier.
