Energy metrics analysis of N identical evacuated tubular collectors integrated double slope solar still

摘要

AbstractThis paper deals with the theoretical analysis of double slope solar still (DS) integrated with N identical evacuated tubular collectors (N-ETC-DS) on the basis of energy metrics. The analysis has been done considering four types of weather condition for each month of year for New Delhi climatic condition. Results of the proposed N-ETC-DS has been compared with DS integrated with N identical photovoltaic thermal (PVT) flat plate collectors (N-PVT-FPC-DS), DS integrated with N identical PVT compound parabolic concentrator collectors (N-PVT-CPC-DS) and conventional DS (CDS). It has been concluded that N-ETC-DS performs best on the basis of exergy based energy payback time, energy production factor and life cycle conversion efficiency followed by N-PVT-FPC-DS, CDS and N-PVT-CPC-DS.Highlights?N-ETC-DS has been analyzed under optimized condition for energy metrics.?N-ETC-DS has been compared with N-PVT-FPC-DS, N-PVT-CPC-DS and CDS.?N-ETC-SS has been found to perform best on the basis of exergy based energy metrics.]]>
