摘要:再生器是太阳能液体除湿系统的核心设备,其效率直接影响整个系统的性能。分析了再生器出口参数由
进口参数和效率直接获得的可行性,并建立叉流液体再生系统,采用氯化锂为再生溶液,Celdek 填料为热质交换
介质,实验测试溶液和空气进出口参数对再生器全热效率和湿度效率的影响规律,并进行线性回归,结果表明:
全热效率主要受溶液流量、温度以及空气流量、温度和含湿量的影响;湿度效率和溶液流量、温度、浓度以及
空气流量关联性强,与其它变量关系很小;线性回归方程计算结果和实验结果误差基本在 20%以内,可通过进口
参数预测出口状态。

Abstract:Regenerator is one of the ponents in a liquid ant air-conditioning system driven by
solar energy, whose efficiency directly affects the whole performance. Feasibility to obtain outlet parameters of
the regeneration through its efficiency and import parameters was analyzed, and a cross-flow regenerator was
established in which LiCl solution and Celdek structured packing were used. Enthalpy efficiency and moisture
efficiency were adopted to describe the heat and mass transfer performance of the regenerator. Influence of
ant and air inlet parameters on the regenerator performance was e
