摘要
为进一步提高液体除湿空调溶液再生性能,提出一种基于太阳能界面蒸发的溶液再生方式.研究溶液种类、浓度对于再生速率和效率的影响,并与传统热再生及膜再生进行对比.结果表明,在一个太阳强度照射下,温度为26℃、质量浓度为40%的LiCl溶液达到0.39 kg/(m2·h)的再生速率,质量浓度为80%的KCOOH溶液达到0.37 kg/(m2·h)的再生速率.与传统的膜再生以及填料塔热再生相比,该方式展现了较高的再生速率,因此基于太阳能界面蒸发方式有望成为一种新型高效的溶液再生方法.
Abstract
To further improve the regeneration performance of liquid-desiccant air conditioning systems,solar-driven interfacial evaporation was introduced in this work for solution regeneration.The effects of solution type and concentration on the regeneration rate and efficiency are studied.This new regeneration method is also compared with traditional thermal and membrane regeneration methods.The results show that,at 26℃,LiCl desiccant with 40%concentration achieved a regeneration rate of 0.39 kg/(m2·h),and KCOOH desiccant with 80%concentration achieved a regeneration rate of 0.37 kg/(m2·h).Compared to traditional membrane and packed-tower thermal regeneration method,this method demonstrated higher regeneration rates.Therefore,this new method has the potential to become a new efficient desiccant regeneration technique.
