Description

Up to half of the world's population faced growing water crisis at an alarming rate especially in developing countries such as African countries. Thus, with abundant salty water and solar intensity in those regions, solar powered desalination system presents an attractive solution towards availability of clean water. HDH desalination system considered a competitive solution. Its performance depends on matching between weather conditions and different design parameters. This fact proves the urgent needs for a robust design tool that is capable of predicting the desalination system performance at a certain location before taken the implementation decision. Present work aims to develop simulation design tool based on TRNSYS and EES software. Experimental data were utilized for validation process where maximum error of about 5.8% achieved. The developed tool was applied on EL-ARISH, Egypt region, as remote areas. Results showed an output of 1kg/h fresh water requires 15m2 of compound parabolic trough collector operating at average solar intensity of 1000W/m2. Improvement was added by integrating an optimization stage to recalculate different optimal design parameters.
