Effects of the dissimilarity of water depth on energy and exergy efficiencies and productivity of solar energy

摘要

This research work investigates the effect of dissimilarity of water depth on energy and exergy efficiencies and productivity of solar still of double slope type coupled to N alike evacuated tubular collectors. The analysis has been done for archetypal days of June and January for complex climatic situation of New Delhi using computer codes inscribed in MATLAB-2015a. It has been concluded that values of average daily efficiencies and productivity increase first and then become almost constant beyond water depth of 0.56 m.
