Enviro–Economic Analysis and Production Cost of Distilled Water Obtained from Cooling Condensing Active Single Slope Solar Still

Abstract

This communication primarily deals with the effect of water cooling condensing cover and helically coiled heat exchanger on single slope solar still integrated with Photovoltaic Thermal Compound Parabolic Concentrators (PVT-CPCs). The design parameters for the active distillation system have been optimized and furthermore production cost of distilled water (₹ 0.11/kg) is obtained. The computational work show that carbondioxide mitigated is 13 ton CO2/annum and the revenue generated is $108/annum on the basis of energy. The proposed active distillation system gives higher efficiency of solar module (12.03% June, New Delhi, India) with higher distilled water (32.50 kg, daily) because of lower solar cell temperature (68 ℃) and cooling condensing cover.
