为了克服全球能源贫困和气候变化，迫切需要绿色建筑。空调系统作为建筑中的耗能大户，必须更加节能环保。吸收式空调系统是一种理想的空调系统，但由于其回热过程中存在能量浪费，导致空调系统性能较低。电驱动膜再生法可以改善这一状况。但是，当浓度差较大时，性能不稳定。双级膜系统可以通过减小浓差来解决这一问题，但缺乏实验支持。为了改进，进行了理论和实验工作：进行了实验以测试真实性能。在此基础上，对影响该模型的一些参数进行了分析。揭示了溶质浓度、电压、温度和溶质迁移量等因素的影响。随着浓度差的减小，双级系统的能量利用率提高，系统性能更好。在某些条件下，双级系统的性能比单级系统高出20%。当吸收剂溶液为LiBr时，双级系统的最大性能系数可大于3。这使其成为未来应用的一个有前途的系统。
To overcome the worldwide energy poverty and climate change, greener buildings are urgently needed. The air-conditioning system, as a huge energy consumer in buildings, must be more energy conservative and environment friendly. Absorption air-conditioning system is an idea option except for its low performance caused by energy waste in the thermal regeneration process. That can be improved with the membrane regeneration method driven by electric power. However, the performance is unstable with higher concentration difference. Double-stage membrane system can solve this problem by reducing the concentration difference, but yet lacks experiment support. To improve, theoretical and experimental work has been made: Experiments have been conducted to test the true performance. Based on which, analysis has been made on some influential parameters. It has revealed the influences of the solute concentration, voltages, temperatures and the transferred solute mass. The double-stage system has better performance as the energy efficiency increases with the decreasing concentration difference. Under some conditions, the performance of the double-stage system is 20% higher than that of the single-stage system. When the absorbent solution is LiBr, the maximum coefficient of performance of the double-stage system can be higher than 3. That makes it a promising system for future application.
