Abstract
Provided herein are atmospheric water harvesting systems that are tailored with an optimal adsorption threshold, based on energy cost and water availability considerations. The systems include a plurality of adsorbent modules, each containing metal organic frameworks of various adsorption thresholds. Such a design enables real time adjustment to achieve optimal harvesting conditions in changing atmospheric conditions, whether for daily or seasonal humidity variations.
Claims17
An atmospheric water harvesting system, comprising:
- a plurality of modules arranged into an adsorption stack, wherein each module independently comprises a metal organic framework positioned on or incorporated into a support, and wherein said metal organic framework adsorbs water from surrounding air when positioned within said adsorption stack;
- a desorption chamber, configured to receive a module saturated or nearly saturated with said water from said adsorption stack, and cause desorption of water from said module as water vapor;
- a condensation chamber, positioned adjacent to or near said desorption chamber, and configured to condense at least a portion of said water vapor from said desorption chamber into liquid water;
- and
- a robotic arm, configured to (i) select and grasp said module in said adsorption stack, and (ii) transfer said module into said desorption chamber.
