Effectiveness and Performance of a Counterflow Liquid Desiccant Regeneration Tower in a Hot-Humid Climate 湿热气候下逆流式液体干燥剂再生塔的效率和性能
再生过程是液体除湿空调系统的重要组成部分。在这项研究中,太阳能辅助液体干燥剂填充再生塔在湿热气候下进行了测试。再生器的设计参数分为受控参数、输入参数和输出参数。使用之前公布的结果评估再生器性能。根据干燥剂的特性,推导并实验评估了一种新的再生器有效性定义。提出了一个经验有效性关联式和一个快速模型来预测出口干燥剂浓度和温度。 此外,还报告了设计变量对有效性的影响。新的有效性和湿度有效性用于优化设计参数。单位:SICitation:ASHRAE Transactions,第115卷,pt。2009年1月1日,芝加哥
The regeneration process represents the vital part of the liquid desiccant air conditioning system. In this study, a solar assisted liquid desiccant packed regeneration tower is tested in a hot-humid climate. The regenerator design parameters are classified as controlled parameters, input parameters and output parameters. The regenerator performance is assessed using previous published results. A new regenerator effectiveness definition based on the desiccant properties is deduced and assessed experimentally. An empirical effectiveness correlation and a quick model are presented to predict the outlet desiccant concentration and temperature. Also, the effect of the design variables on the effectiveness is reported. The new effectiveness and the humidity effectiveness are used to optimize the design parameters.Units: SI
