Thermal analysis of solar desalination system using evacuated tube collector

Abstract

In the developed and developing countries availability of drinking water is the main priority of human being. Fresh water found in rivers, lakes, and ground water constitutes just 3% of water on earth and remaining as hard water. Soft water which is useful for drinking is in shortfall. This research is an attempt to haunt solar energy to desalinate hard water into portable water to add advantage of renewability. A solar thermal desalination system has been proposed whereby heat from solar energy is utilized for heating hard (salt) water which is passed through evacuated tube collector. The steam thus formed is passed through a condenser where it condenses to get soft water. It will be considerably higher amount of fresh water and it would be an ideal solution to produce drinkable water using evacuated tube collector for local residents which is of Indian cities like Pune.
