溶液除湿系统在生产和生活中已得到广泛应用,提高溶液除湿系统节能优势的关键措施之一是提高其再生子系统的效率.本文采用已得到实验验证的填料塔模型和逆流换热器模型,分别描述再生塔中溶液—空气传热传质过程和空气—空气换热器中逆流换热过程,然后用正交设计法安排数值实验.通过对实验结果的方差分析,确定了各运行参数及它们之间的交互作用的相对重要性.方差分析结果表明:以再生塔内水份蒸发速率作实验指标时,重要参数包括溶液入口温度和浓度、干空气与溶质之间的质量流量比率、再生空气入口温度;以再生塔再生效率作实验指标时,干空气与溶质之间的质量流量比率以及溶液入口温度是重要参数;参...

The liquid desiccant dehumidification system has been widely used in industries and lives,And one of the key measures to improve the energy saving advantages of liquid desiccant system is to increase the efficiency of the regeneration sub-system.In this study,models for the regeneration tower and counter-current heat exchanger,which are recognized by previous experiments,are employed and the corresponding VC ＋ ＋ computer programmodules are used to describe the heat and mass transfer processes between the liquid desiccant solution and moist ai...
