Experimental validation of an optimized solar humidification-dehumidification desalination unit

Abstract

This paper presents experimental validation of a solar humidification-dehumidification (HD) desalination unit which has been constructed based on optimization results reported in previous paper. The unit designed and constructed for 10 L/h fresh water production and was tested during 2 months period. The tests reveal that optimization before construction will result in better performance in practice. Productivity is the most important parameter which improved from 2% to 3.5% in previous experimental works to more than 4%. Moreover, experimental results are in agreement with theoretical ones.
