Design of the desalination device of waterand study the effect of the heat exchanger on its efficieny

Abstract

in this research paper an equipment of the water desalination(solar desalination) has been designed .besides thermal exchange has been examined on its proficiency productivity and performance .empirical results on 3td of march 2010 have shown an increase of the desalination productivity the daily desalination productivity reached 184ml/m2.d this happens because of the existing of the exchanger inside and outside the equipment which increases the productivity by its work as additional plate for concentration inside the desalination because the exchanger has less temperature than the inside plate of the glass cover which works as the thermal exchange between the equipment and the surrounding environment . in this way the water will concentrate over the additional concentrate or in large quantity .
