Research Progress on Regenerative Technology and Energy Analysis of Solar Liquid Desiccant Air-conditioning System

本文对太阳能溶液除湿空调系统的最新再生技术进行了的综述，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，对比氯化锂溶液、溴化锂溶液、氯化钙溶液再生分析发现溴化锂溶液的再生进出口浓度差最大，而氯化锂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
