Abstract

In this work a flash vapor desalination unit was assembled which consisted of a solar water-cooled system of three flat plate collectors and a storage tank. A copper coil was immersed inside the tank, the saline water was pumped through the coil and delivered to the flash tank, the vapor then being flashed to the surroundings. The saline water level in the flash tank was taken as a measure of the quantity flashed. The temperature of both cooling and saline water at the inlet and outlet were measured; solar irradiation and wind speed were also recorded. The mass ratio (R) which is the ratio of the rate of the mass flashed to that of saline water circulated and the total unit efficiency were taken as dependent variables. Graphical and numerical optimization methods were conducted to find the values of the dependent variables. The optimization algorithm is described and the results are shown.
