Single basin double slope solar still: Year round performance prediction for local climatic conditions at Southern India

Abstract

In this work, performance of a single basin double slope solar still has been studied theoretically and experimentally. The theoretical model is used to predict the year round performance of the still at the local climatic conditions for the year 2008. Average values of maximum and minimum atmospheric temperatures, wind velocities were taken from meteorological data for last five years. Radiation models were used to predict the global and diffused irradiances on the inclined covers. The time to time variations in transmittance of the cover were considered. The rate of production variation and the total production for first day of the every month had been calculated. The overall production of the still was higher during March, April, August, November, and December and it is around 4 L/day. The average production of the still was 2.1 L/day/m 2 . The economy of the still was also studied and the payback period of the still was three years.

Thermal modeling and exergetic analysis of a thermoelectric assisted solar still

“…6 and also due to the time lag between the evaporation and condensation processes. Similar behavior has been also reported in Shankar and Kumar (2012), and Kulandaivel and Karuppaih (2014).…”

“…This is attributed to the heat capacities of the water and the glass cover which causes the time delay between the solar intensity and water and glass temperature profiles. The same behavior is also reported in studies of Shankar and Kumar (2012), and Kulandaivel and Karuppaih (2014).…”

Effects of solar geometry and operation period on stability of solar desalination systems: a review

“…The important findings of the above-discussed sections are summarized in Table 1. The performance of a single basin double slope solar still was tested for one year in 2008 (Kulandaivel and Karuppiah 2014). The maximum water productivity of the distiller in March, April, November, and December was ~3.8 L/day, ~4.6 L/day, ~4.11 L/day, and ~4.18 L/day, respectively.…”
