A concept note on solar water heater integrated vacuum desalination unit for institutional purpose

Abstract

Energy and water are the main resource that needs to be conserved in the first place all over the world. Since industrial revolution the scarcity of Energy and Water begin to snowball. The use of energy rose rapidly due to the consumption of fossil fuels. By degrading these fossil fuels it lead to pollutant augmentation in ground water which is used for drinking purpose. So, there is a need to conserve the energy resources as well as water to promote energy efficiency and sustainability. This can be achieved through renewable energy sources like solar, wind, hydro, and biomassetc. The renewable energy is a clean and green energy and the most promising alternative technology which promotes sustainable development. The energy of solar is abundant all over the world especially in India. This solar energy must be utilized in an efficient way such that the electric consumption can be gradually minimized. In this paper, a evacuated tube collector (ETC) type solar water heater is integrated with the desalination unit subsequently that leads to acquire heating and purification of water with minimum heat losses in the respective hybrid system. The ETC type solar water heater stores water at high temperature whereas solar still requires heated water for increased evaporation as well as yield. Henceforth,by using this integrated system endorses thermal efficiency, sustainability, social and economic development in the societies.
