A High Rated Solar Water Distillation Unit for Solar Homes

Abstract

India is presently focusing on complete utilization of solar energy and saving fossil fuels, which are limited. Various solar energy systems like solar cookers, solar water heaters, solar lanterns, solar PV lights, and solar lamps are continuously availing by the people of India at a low cost and on good subsidies. Apart from this, India is a solar energy promising country with a good number of solar homes (carrying solar energy systems) in its various locations. The present paper focuses on a unique combination of solar dish cooker (SDC) and solar water heater (SWH) to produce distilled water with a high distillate and a high daily productivity. The procedure has been discussed on the basis of experimental testing to produce distilled water by combining an evacuated type SWH and a SDC. Experimentation has been carried out in MIT, Moradabad (longitude, 28.83°N, and latitude, 78.78°E) by developing the same experimental setup on behalf of solar homes. The daily productivity of distilled water was found around 3.66 litres per day in full sunshine hours for an approximated pH value of 7.7 and a ppm value of 21. The payback period (PBP) has been estimated around 1.16 years of the present system.

Effect of Absorber Types of Conventional Distillers on the Amount of Distilled Water Production

“…The fluctuations of the absorber temperatures are smooth. This phenomenon was also attained by Mirmanto (2003), Saxena and Deval (2016). For the three types of absorbers indicate almost the same temperatures, however, type C elevates little bit higher than other absorber temperatures.…”

Calculating the Quantity and Cost of Distilled Water Produced by Solar Plants to Desalinate Drain Water and use it in Irrigation

“…The results showed an increase in the distillation process in both cases at the lowest costs and that March and April were the best months for production among the months of the year [8]. In 2016, researchers conducted a study in India through the work of a high-energy solar distiller to distill water in homes and benefit from it in daily needs, The results showed that the daily productivity of distilled water is about (3.66L/day) in the hours of sunshine complete [9]. In 2017, researchers conducted an experimental study on a solar device still using a collection box with an open area for water distillation (1 * 0.6) m, The obtained results showed that the amount of distilled water increases with the increase in the amount of solar radiation and higher.…”
