中文摘要	再生器是溶液除湿空调系统中的重要传热传质部件。搭建了叉流再生器性能测试的实验台,并建立了叉流再生器中传热传质过程的数学模型。以溴化锂溶液为除湿剂,采用总换热量、全热效率描述再生器的热质交换总体效果,采用再生量、再生效率描述传质效果,实验测试了溶液和空气的进口参数对再生器性能的影响,并与逆流再生器的实验结果进行了比较。以实验得到的量纲一传质系数作为数学模型的输入条件,数值计算结果与73组实验数据吻合很好,全热效率和再生效率的偏差均集中在±15%以内。; 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 �%.
