Sustainable Energy for Water Desalination System Relative to

The use of solar energy in thermal desalination processes is one of the most promising applications of renewable energy technology. This paper deals with the principle of using solar energy to produce distillate water. The design model contains a solar collector that moves in two dimensions to absorb the direct solar energy, a heat exchanger, two multi-effect distillation units, and a condenser. This model was simulated under Basra weather conditions for four months in 2012. The results showed that the productivity of the proposed desalination system are 5.3, 6.4, 5.3, and 4.4m3/hour for the four months March, June, September and December, respectively. Moreover, inclusion of a thermal fluid heat transfer process, inside the absorber tubes, has improved the productivity of the system.
