The main content of the paper focuses on the theoretical study of the heat exchange between sprayed water and air in a humidification – dehumidification unit. The gained results [7] have been validated by using Hou data [1] and show that, in order to achieve the maximum GOR, the mass flow rate ratio between sprayed water and air depends on the sprayed water temperature and the minimum temperature difference ∆tmin. Particularly, the spayed water temperature should be from 70oC to 75oC when the minimum temperature difference ∆tmin= 5oC.
