Sažetak
Izvršena je teorijska i eksperimentalna analiza tri solarna destilatora sa po jednim bazenom pod dvostrukim nagibom staklenog kolektora: 15o, 30o i 45o u meteorološkim uslovima Ragogara, Guna (24o39' sev. geogr. širine i 77o19'ist. geogr. dužine, Indija). Eksperimenti su izvođeni od 14-16. juna 2017. Detaljna analiza energije i eksergije izvršena je pomoću teorijskog modela Kumara i Tivarija baziranog na regresionoj analizi. Teorijski rezultati dobijeni evaluacijom slažu se sa eksperimentalnim rezultatima. Maksimalna količina slatke vode je dobijena pod nagibom staklenog kolektora od 15o (kol. vode 4,66 l u 14:00 časova) i učešćem solarnog destilatora od 52% odnosno 48% na istočnoj odnosno zapadnoj strani. U 15:00 časova svi destilatori su pokazali maksimalnu termičku efikasnost, tj. 23,69; 29,24 i 25,09% pri nagibu kolektora od 15o, 30o i 45o. Utvrđeno je da se maksimalna eksergija javlja u bazenu sa staklom i vodom kod svih solarnih destilatora sa dvostrukim nagibom.
