Researchers in Israel have proposed an innovative atmospheric moisture harvesting system based on a model where water vapor is separated from the air prior to cooling and condensation. The model simulated its three interconnected cycles (air, desiccant, and water) over a range of ambient conditions, and optimal configurations for different operational conditions. Compared to specifications of commercial atmospheric moisture harvesting systems their model represented saving of 5–65% of the electrical energy requirements due to the vapor separation process. They showed that the liquid desiccant separation stage that was integrated into atmospheric moisture harvesting systems could work under a wide range of environmental conditions using low grade or solar heating as a supplementary energy source, and that the performance of the combined system was superior… read more.
