| Abstract | ||||
| Clean drinking water is essential to humans and other life forms, so this paper investigates the methods of obtaining fresh water from the humid atmosphere. The study was carried out experimentally and theoretically. It was designed and manufactured a simple construction unit for this purpose. The unit was manufactured and tested in Kuwait. The study was extended to analyze the effect of ambient temperature and humidity on the system performance. As the ambient humidity decreases, the mass of water absorbed by the system also decreases due to low potential for mass transfer. The heat transfer analysis was covered. The night-time moisture absorption and the day-time moisture desorption take place in the same unit. The unit was consisted of a flat, blackened, tilted surface and is covered with a single glazing. During the night, the strong absorbent flows down as a thin film over the glass cover in contact with the humid ambient air. Due to absorption of moisture from the ambient air at night, the absorbent becomes diluted. The results are compared with different previous studies. | ||||
