Apstrakt
U Srbiji se najčešće električna energija koristi za zagrevanje sanitarne vode (SV). Kako je oko 70% električne energije dobija korišćenjem uglja koji oslobađa veliki broj gasova sa efektom staklene bašte, korišćenje solarne energije za zagrevanje sanitarne vode u solarnim sistemima za zagrevanje sanitarne vode (STV) ima povoljan uticaj na očuvanje život-ne sredine. Tokom rada solarni sistem za grejanje sanitarne tople vode generiše različite količine toplote iz solarne energije, dobijaju se različite količine izbegnute elekrične energije. U istraživanjma je primenjen softver EnergyPlus.
Korišćeni vremenski podaci su iz ovlašćenih meteoroloških stanica. U ovom radu pokazana je energetska optimizacija solarnog sistema za zagrevanje STV sa solarnim prijemnikom koji funkcioniše tako što koristi ugao nagiba 37.5° i 12 različitih vrednosti ugla azimuta, po jedan za svaki mesec u toku godine. Ovom prilikom je za svaki solarni sistem za grejanje STV izračunat solarni udeo u funkciji ugla nagiba i ugla azimuta i predstavljen odgovarajućim krivama. Takođe je prikazan i mesečni deficit solarnog udela za odstupanja ugla azimuta, kada on u nekim mesecima nije optimalan. Korišćene su odgovarajuće simulacione i optimizacione rutine sa modifikovanom metodologijom Hooke Jeeves algoritma. Solarni sistemi su poboljšani, tako što je dobijena minimalna potrošnja fosilne energije, smanjena upotreba energetskih resursa, maksimizirana energetska sigurnost, kao minimiziran uticaj na životnu sredinu.
