FEATURES AND APPLICATIONS
Water scarcity is one of the burning issues of today’s world. Though water covers more than two third about 70 percent of the Earth’s surface but still fresh water which can be used for drinking and carrying out everyday chores remains scarce only about 2.5 percent. The acute problem of water shortage, is mainly faced by the countries with long coastlines and the island nations, which do not have adequate fresh water sources like rivers and ponds. As a result most of these countries meet their water demands by desalination of sea water which is a very costly affair. Also it may so happen that these desalination plants may fail which will cause acute water shortage. This is what just recently happened in Maldives. So there is an urgent need for countries like Maldives and others, who depend solely on desalination plants to meet their water requirements, to find alternative methods to generate water in order to meet their water security needs.
This project aims to solve this problem. In the coastal areas the relative humidity is quite high around 70-80 percent. So, the air in coastal areas can be used to meet the water needs of people by using a device that works on principle of dehumidification. Such a device is called Atmospheric Water Generator. Three common psychometric methods of dehumidification are temperature drop below the dew point (refrigeration condensing), pressure condensing and wet desiccation.
In this project we use the first method. There are several advantages to this approach. First, it is founded on decades of technical work and innovation. Furthermore, it is a very direct approach and relatively simple to evaluate given psychometric theory and the latent heat of condensation. Virtually all commercial atmospheric water generators utilize this approach to dehumidification.
