摘      要：Atmospheric water harvesting(AWH)is a promising solution to the water shortage *** sorption-based AWH(SAWH)systems seldom obtain both wide climatic adaptability and high energy efficiency due to the lack of thermodynamic *** achieve the ideal harvesting circulation in SAWH systems,the“optimal harvesting window”(OHW)design based on thermodynamic analysis was first proposed and validated by our ***“OHW”theory indicates the water production rate and energy efficiency could be improved by properly reducing the adsorption *** the humidity increases,the optimal adsorption temperature should be closer to the dew point of the *** results revealed that,loaded with 3 kg widely adopted silica gel,the daily water production could reach 5.76-17.64 L/d with ultrahigh energy efficiency of 0.46-1.5 L/*** prototype could also achieve optimal performance in wide climatic conditions in terms of 13-35℃and 18%-72%***,the performance of photovoltaic(PV)-driven SAWH was *** showed that a 1 m^(2)PV panel could generate 0.66-2 L water per day in Shanghai throughout the year,the highest in opening ***,this work introduces a promising concept that can help achieve large-scale,ultra-fast,energyefficient AWH worldwide.
