Abstract:

This paper reviews the current research of water extraction from air. The progress and future trends of different absorbents for absorption of water from air，including solid，liquid，composite water absorbents and other new absorbing water technologies are discussed. The energy utilization patterns for two major methods of water extraction from air，condensation method and absorption/desorption method are summarized and compared. Forecast of water extraction from air is presented on the basis of absorption /desorption method and reasonable use of solar energy or waste heat.

摘要：

综述了空气取水的基本研究现状，对可用于空气取水的固体吸附剂、液体吸收剂、复合吸湿材料以及新型吸湿技术等各类吸湿材料的研究现状和发展趋势进行了详细的讨论，并对冷却结露式取水方法与吸湿/解吸式取水方法的能源利用方式进行了讨论和比较。在此基础上，对采用吸湿/解吸方法同时合理利用太阳能和余热来取水的研究前景进行了展望。
