Apstrakt

Ovaj rad se bavi istraživanjem uticaja arhitektonskog projekta hirurške operacione sale na efikasnost strujanja klimatizovanog ulaznog vazduha u stvaranju sterilne i ugodne sredine u sali. Reč je i o istraživanju odnosa između kretanja vazduha i starosti vazduha i arhitekture operacione sale. U radu je iskorišćen dobro razvijen model računske dinamike fluida (CFD), baziran na modifikovanom k‑ε modelu dve jednačine koji je dalje razvijen i usavršen da bi predvideo režime strujanja vazduha, karakteristike turbulencije, temperaturu vazduha i raspodelu relativne vlažnosti u hirurškoj operacionoj sali. U radu je upotrebljen program 3DHVAC, prethodno razvijen i modifikovan za predviđanje karakteristika vazduha u hirurškim operacionim salama. Nađeno je da energetska efikasnost u klimatizovanim operacionim salama zavisi od konfiguracije arhitektonskog projekta sale i radnih parametara. Arhitektonski projekat prostorije je jedan od suštinskih faktora koji nedvosmisleno utiču na model strujanja KGH, a otuda i na kvalitet vazduha i ugodnost u hirurškim operacionim salama. Na kraju su i neke preporuke za arhitektonske projekte, kako bi se pomogao razvoj optimalnih sistema KGH.
