ABSTRACT
We introduce an Atmospheric Water Generator which works on the principle of Thermo-Electric Couple (TEC) Device. According to the Previous Research papers we had studied that we can extract water from atmospheric air. We noticed that the water can be produce from highly relative humidity air with moderate atmospheric temp. It is highly applicable in desert area, in sea, rural area, etc. Many people in the world do not have access to clean fresh water. Also, drought has plagued many regions in the world, devastating crops and brought societies to the brink of collapse (Such as the severe drought in the city of Cape Town in South Africa right now). The UN has projected that the demand for fresh water will exceed the supply by 40%, so it is time for engineers to step in and find sustainable solution to the water crisis. Our project is trying to address the water shortage problem. Huge amount of water vapor is present in humid atmosphere, especially in Al Khobar where the humidity reaches high percentage, so it is imperative to design atmospheric water extraction and collection system. We will use solar cells and thermoelectric materials to design innovative, simple and inexpensive atmospheric water generator. This water generator could be used in homes to provide people with fresh water or can be used in farms for irrigation purposes. Fresh water supply is one of the most limiting conditions for the populations of arid regions. A concept of extracting water from humid air has proven to offer a viable solution for such regions in world energy scenario. Limits of water production from atmospheric water vapour are investigated for cases where fresh hot humid air is cooled over evaporator coils of refrigeration machines and then directed to open localized areas. This application may be considered as a source of limited amounts of potable water at a free cost since the water is a by-product of the climate conditioning process. For high air velocities, water yield was found to diminish due to insufficient evaporator capacity. On the other hand frosting effect was found to bind the vapour condensation process due to coolant starvation. A working chart was developed for quick prediction of water yield for any combination of atmospheric air temperature in the range (25 < Ta < 40°C).
