HARVESTING OF WATER FROM AIR USING HELICAL COIL

Water scarcity has become a worldwide issue in the current era, this issue is more complicated in the arid areas, where it rains rarely and there is hardly any freshwater source at all. Hence, there is a serious need to find new, sustainable, alternative ways to get drinking water. One of the most interesting methods to get clean water is harvesting humidity from air. Many new initiatives have been taken to develop this old way of getting water, and many technologies have potential to solve the challenge of getting a new, sustainable and renewable source of fresh water in desert areas. This paper presents a thermal process of cooling and dehumidifying the atmospheric air passing through helical coil and extracting water from it. The main objective of the paper is to design a thermal experimental setup as well as a helical coil capable of enchancing the cooling and dehumidifying process. It is known that the arid areas have a hot temperature, where as the underground soil is actually cooler. Hence, a pumping device that pushes the surrounding air with humidity under the ground to pass through pipes network where the humidity will start condensing on the internal walls of pipes, then, the water drops will leak from the pipes directly to the roots of plants in the field or can be used for drinking purpose.
