Abstract :The application of the integrated solar‐energy-based systems for water desalination and power production to some Iranian coastal regions has been investigated. For this purpose, the Integrated Multi Effect Desalination insert ignore into journalissuearticles values(MED); and Solar Rankine Cycle insert ignore into journalissuearticles values(SRC); are used. This work investigates the effects of the main thermodynamic parameters on the systems located at the southern Iranian cities of Chabahar, Qeshm, Kish and Asaluyeh. For each selected sites, the net power output of the system is 50 MWe. The results show that total exergy destruction is the highest for steam generator and cavity receiver which is in the range of 61% to 64% in several cases. Also, the Chabahar has the less total exergy destruction and the freshwater production is about 270.8 kg/s as most production. In addition, at other sites, the integrated cycle can produce about 266.2 kg/s of freshwater. Furthermore, the most total exergy destruction is related to Asaluyeh.
