摘要
A continuous cycle unit to extract water from air was built, in which a new composite adsorbent SiO 2· x CaCl 2· y H 2O(CaCl 2 mass content is 38 4%)prepared by the authors was used.Each adsorber contains 1 5 kg 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 27 kg fresh water was obtained on night time operation(air average temperature 10 4 ℃ and relative humidity 77%), and 0 15 kg 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 0 kg adsorbent could be filled in each adsorber, and 0 06 kg fresh water was obtained in the condition of air average temperature 17 8 ℃ and relative humidity 55% with the same operation time.
