- Abstract
This paper communicates the theoretical analysis of the double slope solar distiller unit augmented with N identical parabolic concentrator integrated evacuated tubular collectors (NPCETCDS) on the basis of energy metrics and efficiency for the climatic condition of New Delhi. Four weather conditions have been taken for computation. The input data required for calculation has been taken from the Indian Meteorological Department, Pune, India. The computational program has been written in MATLAB. The calculation has been performed for eight collectors and flow of fluid mass per unit time of 0.012 kg s–1. Results of NPCETCDS have been compared with results obtained for double slope solar distiller unit augmented with N identical evacuated tubular collectors (NETCDS) for the same number of collectors, the flow of fluid mass per unit time, basin area, and similar weather conditions. It has been concluded that exergy based energy payback time is lower by 88.50%, exergy based life cycle conversion efficiency is higher by 51.93%, and daily exergy efficiency is higher by 78.01% for NPCETCDS than NETCDS for the same number of collectors, the flow of fluid mass per unit time, basin area, and similar weather condition.
