Abstract:
In present Thesis, the HDH desalination system has designed and fabricated based on three different functions. Two-stage bubble column humidification-dehumidification system, heat recovery converter, and the elimination of the cooling system are among the innovations of this study.Also, the desalination system is processed and controlled by a control system based on the Python language. The experiment is designed for three different systems based on the three different functions, different maximum temperatures and different mass ratios of water to air have been taken into account. Essential parameters of HDH systems have been analyzed in this study. The experimental results have pointed out that although the elimination of the cooling system produce less desalinated water, butit reduced the production cost. In other hand, the study has shown that the increment of the maximum temperature and the mass ratio increases the water production for all of the three systems. As it was seen, as the maximum temperature increases from 66 to 86, the water production increases up to 250%
