Abstract:	Magistrska naloga se ukvarja s problemom, kako najugodneje hladiti pisarno za dobro počutje ljudi v njej. V ta namen se je naredil model pisarne, ki vsebuje vso opremo v pisarni, sedečega in stoječega človeka ter klima napravo. Problem je bil kasneje na osnovi računske dinamike tekočin simuliran v programskem okolju Ansys CFX, pri čemer so se skozi različne simulacije spreminjali vhodni parametri, kot so moč klimatske naprave, vrsta le-te in postavitev klimatske naprave. Kot osnovo smo vzeli klasično notranjo enoto ločljive izvedbe, kasneje pa tudi različici s kasetno enoto in talnim konvektorjem. Naloga se posveča analizi faktorja udobja PMV in DR indeksa, ter analizi temperaturnih in hitrostnih polj v prostoru. S pomočjo teh indeksov smo izvedeli, da najugodneje vpliva na človekovo počutje talni konvektor. Ta povzroča najmanjše hitrosti, najnižjo razliko v temperaturnih polij ter najugodnejši faktor udobja v prostoru.

Title:	Determination of comfort factors in business room using computational fluid dynamics
Abstract:	The master's thesis deals with the problem of cooling the office in the most favourable way for people's well-being. For this purpose, an office model was done, which contains all office equipment, a sitting and standing person and a cooling device. The problem was later simulated in the Ansys CFX software environment on the basis of computational fluid dynamics, where input parameters such as power of the air conditioner, type of the air conditioner, and the location of the air conditioner were changed through various simulations. As a basis, we took the classic split indoor unit, and later also the version with a cassette unit and a floor convector. The thesis is focused on the analysis of the PMV and DR index comfort factors, as well as the analysis of temperature and velocity fields in the room. With the help of these indexes, we have determined that floor convector has the most beneficial effect on the well-being and satisfaction of people in the office.
Keywords:	comfort factors, computational fluid dynamics, air-conditioned room, simulation
