Aiming at heat and mass transfer process of the adiabatic countercurrent dehumidifier,adopting dehumidifying effi-ciency,volumetric mass transfer coefficient and moisture resistance as the evaluation index of the dehumidification performance, the correlative mathematical model was constructed;By experimenting on the moisture device of adiabatic countercurrent packed tower with LiCl liquid as dehumidizer,compares of experimental and simulation results to verify the reliability of the theoretical model;And based on multiple groups of measured data,proposed the experimental correlation for evaluation index of the adiabat-ic countercurrent dehumidifier by the multi-element linear regression method,and the correlation coefficient was close to 1 ,in or-der to provide certain reference for optimizing the performance of liquid desiccant air conditioning system.%主要研究了绝热逆流除湿器的传质以及传热过程,选用除湿效率、体积传质系数和湿阻作为评价除湿性能的主要指标.本文对此搭建了相关的数学模型;在搭建的以LiCl溶液为除湿剂的绝热逆流填料塔除湿装置上进行试验研究,并与仿真结果进行对比,验证了理论模型的可靠性;并基于多组试测数据,应用MATlab多元回归法,提出了适用于LiCl溶液绝热逆流除湿器评价指标的试验关联式,且关联系数均接近1,可以为溶液除湿空调系统的性能优化提供相关的参考.
