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.
Claims7
A system, comprising:
- a plurality of modules each containing at least one metal organic framework having an adsorption threshold humidity above which said at least one metal organic framework adsorbs water from air and below which said at least one metal organic framework desorbs water to said air, said adsorption threshold humidity differs between said plurality of modules;
- and
- a controller configured to select one or more modules to absorb said water from said air, wherein said controller configured to select said one or more modules based on one or more of:
- relative humidity of said air;
- adsorption threshold humidity of said at least one metal organic framework;
- adsorption rate of said at least one metal organic framework;
- energy cost to desorb said water from said at least one metal organic framework;
- and
- level of water reserves.
