摘　　要：太阳能溶液除湿空调系统是一种具有较大节能潜力的新型空调系统。然而,太阳能热再生系统严重依赖于环境工况,在高温或高湿的气候条件下其再生后得到的除湿溶液将不能满足除湿的需求。提出一种用于溶液除湿空调系统的新型太阳能溶液预处理电渗析再生系统,分析了该系统的工作原理,建立了该系统的耗能模型,并与传统太阳能热再生系统进行了对比研究。研究结果表明,太阳能溶液预处理电渗析再生系统具有较高的节能潜力。The liquid desiccant air-conditioning system has attracted more and more attentions in recent years. As a renewable energy, solar thermal energy can be used to regenerate the desiccant solution in the liquid desiccant air-conditioning system. One problem in the solar thermal energy regeneration system is that solar energy depends on weather conditions, so that the solar thermal energy regeneration system cannot meet the dehumidification requirements when the air is hot and wet. In this paper, a new regeneration system for solar desiccant pre-treatment electrodialysis is proposed to improve the reliability of solar desiccant regeneration system. The performance of the new system is compared with that of traditional solar thermal regeneration system and the influential factors on the performance of the new system are examined. The results reveal that the new system will be more energy efficient.
