Abstract

A solar-powered desalination system using condenser integrated with concave solar collector and centrifugal pump was developed for producing fresh water under different operational conditions. Systems temperatures added to ambient temperature were measured with hour intervals, under all experimental conditions for both solar desalination systems. Heat and mass transfer regimes were conducted for the condenser and heat exchanging tubes. Performance of the two systems was studied as a function of change in water salinity level and water tank flow rate and evaluated in terms of recorded temperatures, water productivity and cost. The experimental results may reveal that the developed system increases water productivity for all water salinities compared with the ordinary system due to the presence of centrifugal pump. The same results may also reveal that water productivity increased and cost decreased by increasing water flow rate using the developed system while the vice versa. Results obtained from two systems are analyzed for suitability of drinking by measuring the minerals.
