Abstract
In this study, a hybrid commercial solar dish concentrator (SDC) integrated with a multi-effect distillation (MED) unit is thermodynamically modeled for the desalination process. A mathematical model implemented in MATLAB software is developed to simulate the proposed SDC/MED system to analyze its performance under the conditions of Tianjin (TJ), China. An energy analysis viability for assessing the life cycle of the SDC/MED system is also performed.
The results demonstrated that, despite the site's solar radiation changes throughout the day, the desalinated water output for the proposed SDC/MED system is sufficient. In addition, the TJ-SDC/MED system is more cost-efficient than comparable standalone desalination systems. The simulation of the SDC with the MED unit of five effects yielded average productivity of roughly 95.5 kg/s, a specific cooling water flow rate of 1.689, and an overall performance ratio of 223.3. It is recommended that the hybrid SDC/MED system is an efficient choice for producing potable water in large scale desalination applications.
