Abstract:
In this paper a solar desalination unit with a parabolic dish collector has been designed and characterized. Efficiency measurements of the collector provided 0.69 for the intercept efficiency and 1.9 W/m2K for the first order coefficient. The effect of the feed flow rate on the distillate output flow rate has been studied. The thermal efficiency of the total distillation process including evaporation and condensation has been also determined for different feed flow rates. The maximal measured efficiency for five in series connected collectors achieved 50.2 {6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465}. The designed unit can be combined with a solar still for direct solar desalination. It can also be used as the first stage of a (MEB) or (MSF) desalination plant.
