Apstrakt

Sistem za podnu distribuciju vazduha (UFAD) je strategija mehaničke ventilacije koja je bila tema nedavnih studija zbog nekoliko potencijalnih prednosti, kao što je poboljšana toplotna udobnost u zatvorenom prostoru. U sistemu UFAD, zauzeta zona se direktno napaja klimatizovanim hladnim vazduhom, formirajući termičku slojevitost od donje zone prostora do njegove gornje zone. Ova studija predlaže da se obezbede efekti termičke stratifikacije i distribucije brzine vazduha na toplotni komfor u zatvorenom prostoru. S tim u vezi, u obrazovnom prostoru sa 30 osoba, izvedene su četiri različite konfiguracije dovodnih difuzora uključujući tri UFAD sistema i jedan sistem distribucije vazduha za ventilaciju (DVAD). Štaviše, detaljnije se istražuje mogućnost lokalne toplotne nelagodnosti i promaje, koja nastaje usled poremećaja protoka vazduha u UFAD sistemima. Inicijalno generisanje mreže je sprovedeno korišćenjem GAMBIT softvera, a softver OpenFOAM je korišćen za simulaciju UFAD i DVAD sistema protoka vazduha sa različitim konfiguracijama difuzora. Rezultati su pokazali da je detaljno razumevanje vazdušnog transporta i njegovih posledica na toplotni komfor u četiri različita slučaja i pokazali da konfiguracija difuzora ima značajnu ulogu na toplotni komfor u zatvorenom prostoru.
