Design and optimization of an atmospheric water generator using thermoelectric cooling modules

An Atmospheric Water Generator (AWG) is a device that extracts water from humid air by cooling it below the dew point, compressing the air, or exposing the air to hygroscopic substances. The AWG incorporates the concept of thermoelectric cooling (TEC) to condense water vapor from humid air and is de...

Description
Summary:An Atmospheric Water Generator (AWG) is a device that extracts water from humid air by cooling it below the dew point, compressing the air, or exposing the air to hygroscopic substances. The AWG incorporates the concept of thermoelectric cooling (TEC) to condense water vapor from humid air and is designed to produce two liters of water in twelve hours from the air at 30 °C and 80% relative humidity (RH) to meet the average water need of a person. Experiments are conducted on a prototype with the intent to study the effect of airspeed on the amount of water condensed and thus infer the optimum speed for maximum water output. The use of TEC for condensation in AWG is economical on a small scale and does not compromise on the environment in the long run. The results obtained can influence future designs of the same.
