摘要: Desalination using solar stills is an ancient economic method for water desalination. Over the years, research and development in area of still has resulted increased distillate yield by means integration PCM (phase change material), photo-voltaic thermal (PVT), etc with still. Nano-PCM upcoming technology which modifies performance PCM. The aim this to analyze efficiency 20 including nano-PCM based considering various input output criteria integrated fuzzy analytical hierarchy process (AHP) data envelopment analysis (DEA). derived here relative regard parameters considered study. result infers that, even though productivity stepped sun tracking system was high, but when techno-economic aspects were it not among top stills. indicated pyramid type still, single slope PVT, NPCM (paraffin + copper oxide), (paraffin + titanium dioxide) (paraffin) occupies five positions 100, 88.47, 88.46 76.93% respectively.
