Abstract
Water scarcity is one of the major issues which India is currently facing. About 600 million Indian population is facing high to extreme stress over water. Despite water resources, India’s eastern states are actually water poor as households and individuals remain inadequate of water supply. These eastern states are blessed with humid climates where average yearly relative humidity and dry-bulb temperature range from 75 to 85% and from 20 to 30 °C, respectively, which clearly indicates that these regions have high water extraction potential from the atmosphere. Atmospheric water generator is a reliable technology to harvest water from the atmosphere. In this paper, an analytical investigation is presented to analyse the potential of atmospheric water generator (AWG) for eastern Indian states. Amount of water yield was calculated for different major cities and towns of eastern states around the year. Monthly condensate extraction remained in the range from 1800 to 2100 kg. Per kg cost of condensate for different evaporator temperatures was investigated. For evaporator temperature at 5 °C, the cost varied from 0.95 INR to 1.30 INR. It was noticeable that condensate extraction was clearly a function of air humidity ratio and temperature. The condensate yield follows a similar trend of relative humidity.
