Experimental Investigations and Modeling of Atmospheric Water Generation Using a Desiccant Material

Harvesting atmospheric water by solar regenerated desiccants is a promising source that energy-efficient, environmentally clean, and viable. However, the generated amounts of are still insignificant. Therefore, more intensive fundamental research must be undertaken involving experiments modeling. This paper describes several experiments, which were conducted to predict improve behavior absorption/desorption Calcium Chloride (CaCl2) desiccant, where uncertainty did not exceed ±3.5%. The absorption effect in deep container was studied experimentally then amplified pumping air into solution. latter measured thin solution layer under variable ambient conditions. Pumping inside liquid desiccant containers increased rate 3.75% per hour, yet when using solution, it found have 6.5% hour same maximum amount absorbed vapor partial pressure relation investigated, mean absolute error between proposed formula content 6.9%. An empirical formula, one-dimensional mathematical model, developed coupling three differential equations compared experimental data. model 3.13% 7.32% for desorption, respectively. Governing conservation subsequently formulated. models combined solved numerically. Findings obtained from simulation Additionally, scenarios modeled tested Jeddah, Saudi Arabia, various
