Resumo
Experimental and theoretical work investigates the principal operating parameters of a proposed desalination process working with an air humidification-dehumidification method. The main objective of this work was to determine the humid air behavior through single-stage of desalination system. The experimental work studied the influence of the operating conditions such as the water temperature, the saline water level and the air flow rate to evaporator chamber on the desalination performance. The experimental results show that, the productivity of the system increases with the increase of the water temperature and the decrease of the airflow rate. The productivity of the system is moderately affected by the water temperature and airflow rate and slightly affected by the water level. The efficiency of the desalination system is higher for mass flow rates of Ma=12.6 and Ma=14 kg/hr at different water levels. At 80 C, the productivity of the system is higher at different water levels and airflow rate. Within the studied ranges, the maximum productivity of the system reached to 0.81 kgw/kga at 87 C for water and Ma=4.2 and Ma=8.4 kg/hr. A good agreement had been achieved with productivity calculations.
