ABSTRACT In this paper, the variation laws of parameters in air bubbling humidification of solar desalination process are studied. The experimental system and experimental phenomenon are introduced. The parameters of remaining water quantity, humidifying capacity, and water temperature at any instantaneous time in humidifier are calculated and analyzed under different conditions by differential equations of energy balance and mass balance. The results show that the water temperature and the humidifying capacity are changed significantly with time increased in the initial humidifying stage. The change of these parameters depends on heat supplied to the water in the humidifier, whether the heat is higher or lower than the one absorbed by the water evaporating. If the supplied heat is higher, the water temperature and the humidifying capacity will increase in the initial humidifying stage; otherwise they will decrease or remain unchanged. After a certain time of humidifying, these parameters tend to be stabl...
