Investigation Of Humidification Dehumidification Unit Designed For Utilizing Solar And Waste Energy

Abstract

The current work addressed the thermodynamic performance analysis of novel humidification dehumidification deionization system which utilizes the waste heat of household chimney of kitchen for water heating. Mathematical analysis based upon conservation principle of mass and energy has been done for the components of system. It has been applied to reveal the effect of mass flow rate of air and water on the productivity of potable water. The productivity increases (obtained maximum production of water is 6.5 kg/day) with increases air mass flow rate from 0.6 kg/min to 3 kg/min. Moreover, it also showed substantial dependency of mass flow rate of water on rise in production. The maximum value found 6.7 kg/day and 7.5 kg/day by raising the water mass flow rate in humidifier and dehumidifier respectively. Finally, the performance enhanced by the conceptual system has been assessed in terms of GOR and compared with conventional system. In addition, higher value of GOR of the theoretical system indicates the optimum uses of thermal energy in production of clean and drinkable water.
