Experimental and theoretical energy and exergy analysis for a solar desalination system Original Research Article

This study presents an experimental and theoretical energy and exergy analysis for a solar desalination system consisting of a solar collector and a humidification tower. A mathematical model is developed and the air and water characteristics across the collector and the humidification tower are predicted. The model is verified against measured data for air temperature, water temperature, and air humidity. The results indicate the high exergy efficiency of the solar desalination system. The overall exergy efficiency increases by a decrease in humidification tower length, a decrease in inlet air temperature, and an increase in tower diameter.
