A Study of Effect of Some Factors on Effectiveness of A Single-Effect Vertical Diffusive Solar Distiller

Abstract

In this research, the effect of some factors on the effectiveness of a single-effect vertical diffusive solar distiller, with a design productivity of 5 [L/m²], was studied. It was equipped with a flat solar collector, which was the indirect source for obtaining the necessary thermal energy for the single-effect vertical diffusive solar distiller. These factors were ambient air temperature, intensity of solar radiation, wind speed, humidity, temperature of the flat solar collector, and temperature of the vertical diffusion single-effect solar distiller. During the days 30 May, 14 June, 5 July and 19 August of year 2021. The readings related to these factors were taken during each hour of the experiment, which lasted for 5 hours, and the results were analyzed using the multiple linear regression model to determine the effect of the studied factors on the productivity of single-effect diffusion vertical solar distiller. The study results showed that there were significant differences at the level of 5% in relation to solar radiation and temperature of solar collector and temperature of the single-effect diffusion vertical solar distiller and Ambient Air Temperature. As for the wind speed and humidity, the differences were apparent. The highest correlation coefficient for the single-effect diffusion vertical solar still temperature was 0.83, and this indicates that the solar collector that was used in the research It was a good way to secure the heat energy needed for distillation to occur.
