| 摘 要： | 本文依据氯化钙溶液和氯化锂溶液对空气中水蒸气的不同的吸收能力,提出并搭建了两级双溶液除湿/再生模块实验装置.对氯化钙溶液的预除湿能力进行了实验验证,分析了处理空气流速、氯化钙溶液流速和氯化锂溶液流速对模块的除湿性能的影响,以及再生空气速度对系统再生性能的影响.并进一步计算了系统的能耗情况,在增加空气热回收率为50%的再生空气热回收器的典型工况下,最低平均再生热量降低至3.3 kJ/g,系统COP为2.05.

| Abstract: | An experimental setup of two-stage liquid-desiccant dehumidification/regeneration has been built based on the difierent absorbing water abilities of calcium chloride and lithium chloride.The experimental results prove that calcium chloride can pre.dehumidify air effectively,and lithium chloride can deeply dehumidify air and assure the requirement of the air humidity ratio.The effects of air velocity and desiccant flow rate on the dehumidification performance are investigated,as well as the effect of air velocity on the regeneration performance.It found that the COP of the system is 2.05 when the average regeneration heat is 3.3 kJ/g,the lowest among the investigated conditions. |
