Exergoeconomic and Enviroeconomic Analyses of Double Slope Solar Desalination Unit Loaded With/Without Nanofluid: A Comparative Study

Abstract

The analysis of basin-type double slope desalination unit based on solar energy is the demand of time as there is an acute shortage of drinking water throughout the globe particularly developing and underdeveloped countries. Only less than 1% of water is within the reach of human beings and this small amount of water is also getting polluted day by day due to huge population growth, industrial revolution, and many other anthropogenic activities. The technology of purifying water is known to human beings from sixteenth century as per the history; however, this technology has not been popular till date due to low output, high initial investment, and non-availability of technician at local level. The exergy analysis locates the losses taking place at different components of the system and hence, it provides a way to minimize the exergy loss occurring at different points of the system. Exergoeconomic analysis relates the exergy with uniform end-of-year annual cost and it provides a way to improve the performance of the system. On the other hand, enviroeconomic analysis controls the pollution of the environment by giving motivation for reducing pollutants and encourages the use of renewable energy technology which does not create pollution. This paper deals with the review of basin-type double slope solar still loaded with/without nanofluid on the basis of exergoeconomics and enviroeconomic parameters. It has been observed that the use of water-based nanofluid enhances the performance of double slope solar desalination unit on the basis of exergoeconomics and enviroeconomic parameters. At last, various types of double slope passive and active systems have been compared and discussion has been provided followed by the recommendation.
