ABSTRACT

Solar distiller is a device which allows using the heat ofthe sun to evaporate water clean or dirty and condense fresh water for drinking and other industrial use. This work presents the analysis of a solar water distillation system. There is important need for good drinking water in the world today due to harmful [effects of water borne diseases. Fortunately, solar distillation is very rewarding in terms of operating and maintenance cost. Solar distiller is simple in construction, cheap and easy to use but has a drawback of low productivity. The water used in this work is I collected from the borehole in Michael Okpara university of agriculture of Umudike and experiment was performed at the department experimental field in Michael Okpara university of agriculture Umudike. The fluid and surface temperature were measured and: recorded with a Thermocouple at regular interval of three hours. It was concluded that the performance of the developed solar water [distiller was affected by the temperature and solar intensity and relative humidity ofthe area it was tested. The highest irradiance level of 905.4 W/m2' was observed on day one, the highest ambient temperature of 38 °C was also observed on day two. The highest rise inlet temperature was observed on day one with a temperature rise of 45.5 °C between two noon. It is noteworthy ithat day two had the lowest irradiance levels. The relative humidity was highest at 69.4% and was recorded at day three. This shows that there were variations in the solar radiation, relative humidity and Temperature readings.
