Abstract
At places far from the energy grid lines, freshwater is sometimes needed. Consequently, even countries with rich energy resources, such as the Arabian
Gulf countries, have shown strong interest in desalination processes that often use renewable energy sources. In the present work, a desalination unit
depending on the humidification-dehumidification principles is fabricated and tested under Baghdad, Iraq conditions. The HDH system under study
consists of 6 parabolic trough solar collectors (PTSC) of a total aperture area of 8.772 m2
, the humidifier, and the dehumidifier and a tracking system.
The effects of salty water flow rate and the HDH air-water configuration cycles on the system performance are investigated. The results revealed that
the maximum freshwater productivity is about 6.37 lit/day during the testing period (6 hours per day extended from 9 am to 15 hr); the average daily
productivity is 1.062 lit/hr when the salty water flow rate is 1lit/min. Increasing salty water flow rate above 1 lit/min deteriorates the productivity of
freshwater. The best configuration of the air-water cycle is the closed air open water circuit.
