| Abstract: | A continuous cycle unit to extract water from air was built, in which a new composite adsorbent SiO2•xCaCl2•yH2O(CaCl2 mass content is 38.4%)prepared by the authors was used.Each adsorber contains 1.5kg adsorbent.The operating characteristics of the unit were measured in the condition of Februany and March in east China.When adsorption and desorption time was two hours, 0.27kg fresh water was obtained on night-time operation(air average temperature 10.4℃ and relative humidity 77%), and 0.15kg fresh water was obtained on day-time operation(air average temperature 22.2℃ and relative humidity 44%).When macro-porous silica gel is taken as adsorbent,1.0kg adsorbent could be filled in each adsorber, and 0.06kg fresh water was obtained in the condition of air average temperature 17.8℃ and relative humidity 55% with the same operation time. |
