Description
Summary:The origin and continuation of mankind is based on water. Water is one of the most abundant resources on earth, covering three-fourths of the planet's surface and about 97% of the earth's water is of high salinity. However, the increase of the world population associated to the agricultural and industrial developments involved an increase in the demand of fresh water: Desalination seems to be the solution of this acute problem and the key to meet the future challenges for producing fresh water. Desalination requires large amounts of energy, today mostly from fossil fuels. It is therefore favorable to rely on renewable energies like wind energy, an environmentally-friendly energy source, to desalinate seawater. The main objective of this paper is the study of the possibility to install a single-effect mechanical vapor compression unit (MVC unit) using wind power in the region of Gabes. The paper includes an estimation of the wind energy potential in this region and a study of the influence of the chosen operating temperatures on the compressor specific power consumption of the MVC unit.
