methodology of procedure to convert hot air into water in brief
Answers
Answer:
Many atmospheric water generators operate in a manner very similar to that of a dehumidifier: air is moved over a cooled coil, causing water to condense. The rate of water production depends on the ambient temperature, humidity, the volume of air passing over the coil, and the machine's capacity to cool the coil. These systems decrease air temperature, which in turn reduces the air's capacity to carry water vapor. This is the most common technology in use, but when powered by coal-based electricity it has one of the worst carbon footprints of any water source (exceeding reverse osmosis seawater desalination by three orders of magnitude) and it demands more than four times as much water up the supply chain than it delivers to the user.[2]
An alternative available technology uses liquid, or "wet" desiccants such as lithium chloride or lithium bromide to pull water from the air via hygroscopic processes.[3] A proposed similar technique combines the use of solid desiccants, such as silica gel, Metal–organic framework and zeolite, with pressure condensation.[4] Direct drinking quality water generating devices using sunlight is also under development.[5]
It is said to take 310 Wh to make 1 liter of water.[6]
