Apstrakt
U toku je napredak u razvoju klimatizacionih sistema u sportskim objektima pri-menom nekoliko tehnologija za hlađenje unutrašnjeg/spoljašnjeg prostora, kao što su stadioni i sportske arene, radi uštede energije i obezbeđivanja toplotnog komfora. Najozbiljniji izazov za klimatizaciju spoljašnjeg prostora jeste teškoća da se regulišu temperatura i vlažnost na otvorenom prostoru, kao i ogromna količina energija koju troši rashladni sistem. Glavni zadatak kod analiziranog modela bio je da se obezbedi bolji metod za raspoređivanje vazduha kojim se postižu ugodni uslovi sredine za igrače i gledaoce unutar sportskog objekata. Cilj ovoga rada jeste da ispita tehničke aspekte kojima se studija bavi, kako bi se proučila efikasnost kliamtizacionog sistema pomoću pravila računarske dinamike fluida (CFD), s ciljem da se odredi najbolji način za raspoređivanje ulaznih otvora za vazduh i simulira vazdušna struja, da bi se sprečavanjem visoke temperature i vlažnosti postigao prihvatljiv komfor za ljude. Dati su primeri za arenu za skvoš, teren za rukomet i fudbalske terene. U ovom radu se numerički ispituje uticaj mesta i broja dovodnih i odvodnih otvora za klimatizaciju na kvalitet vazdušne struje u prostoru za gledaoce unutar sportskog objekta. Ovaj rad je usmeren na predviđanje obrazaca vazdušnog strujanja i toplotnog ponašanja kroz ispitivanje režima strujanja vazduha i sadržaja vlage unutar prostora za gledaoce. Takođe, u radu se ispituje ponašanje prenosa toplote kroz analizu profila temperature i relativne vlažnosti unutar tog prostora. U ovom istraživanju su korišćenje tehnike simulacije računarske dinamike fluida (CFD).
