摘要
本文对太阳能溶液除湿空调系统的最新再生技术进行了综述,并对太阳能光热再生、太阳能光伏再生和太阳能光伏/热(PV/T)再生这3个再生方法进行了模拟对比。结果表明:在理想状态下,光伏/热电渗析(PV/T-ED)再生比光伏电渗析(PV-ED)再生节能40.5%,光伏电渗析再生比光热再生节能51.6%。光伏/热电渗析再生系统在理想工况下运行时,对比LiCl溶液、LiBr溶液、CaCl_2溶液再生分析发现LiBr溶液的再生进出口浓度差最大,而LiCl溶液再生后除湿能力最强。
Solar liquid desiccant air-conditioning represents a new,environmentally friendly,and energy-saving air-conditioning system.Solar-energy solution regeneration is one of the most important aspects of the system.In this study,a comprehensive review of the latest regeneration technologies for solar liquid desiccant air-conditioning systems is presented.The following three regeneration methods were simulated and compared:photothermal,photovoltaic,and PV/T.The results showed that under ideal conditions,the PV/T-ED regeneration was 40.5%greater than PV-ED regeneration in terms of energy-saving,whereas PV-ED regeneration was 51.6%better than PT regeneration.When the PV/T-ED regeneration was operated for LiCl-H2O,LiBr-H2O,and CaCl2-H2O under ideal conditions,it was found that the LiBr-H2O had the largest concentration difference between the inlet and outlet,whereas the LiCl-H2O had the strongest dehumidification capability after regeneration.
