摘要
The present work deals with an experimental study of a solar desalination unit using the humidification-dehumidification (HDH) process. A bench-scale desalination unit was designed and tested in Bizerte, Tunisia. Humidification is achieved through a humidifier with saline water falling on its absorber plate, and dehumidification is realized by means of a tubular heat-exchanger condenser. The desalination unit operates with open-water and open-air cycles. Thermal performances as well as fresh water production of the HDH desalination unit were evaluated via measurements of air and water temperatures and flow rates. Measurements were conducted in free and forced convection. Special attention was focused on the influence of air velocity on the fresh water production of the desalination unit. The optimal air velocity, corresponding to the maximum of fresh water production, was found to be 3.34 m/s.
