【 摘 要 】

Only three-dimensional of the world's water is H2O, and common fraction of that's tucked away in frozen glaciers or otherwise out of stock for our use. As a result, some 1.1 billion individuals worldwide lack access to water, and a complete of two.7 billion realize water scarce for a minimum of one month of the year. An AWG extracts water from air. Water vapour within the air are often extracted by condensation-cooling the air below its saturation point, exposing the air to desiccants. At the same time applying thermophoresis method where the system is cooled to its max and surrounding atmospheric air is forcefully heated such that during there contact water droplets formation is increased and efficiency is increased which would be inversely proportional to the time taken. Even if applying cascade system of refrigeration, the efficiency of water generation from humid air is increased.
