Abstract

V diplomski nalogi sta predstavljena eksperimentalna metoda in numerična metoda, s katero smo določili temperaturni profil v ogrevani terminalski učilnici. Analizirali smo temperaturno porazdelitev zraka v učilnici, ki je lokalno greta s klasičnim toplotnim prenosnikom (radiatorjem) s stalno temperaturo. Za eksperimentalno meritev smo uporabili termistor, s katerim smo izmerili temperaturni profil v učilnici. Za numerično metodo pa smo uporabili programski paket Ansys Workbench 11.0 za izdelavo tridimenzionalnega modela prostora in mreženje ter Ansys CFX 11.0 za analizo in prikaz rezultatov. Glede na pridobljene podatke smo nato primerjali, ali je numerična metoda dovolj zanesljiva, da se lahko uporablja za prikaz dejanskega stanja v učilnici.

Secondary title:	Experimental and numerical analysis of thermal conditions in heated computer room
Secondary abstract:	In this Diploma assign there are presented the experimental method and numeric method. With last we defined temperature profile in heated terminal classroom. We analysed the air distribution in classroom which is locally heated with classic heat transmitter (radiator) with constant temperature. For experimental measurement we used thermistor with which we measured temperature profile in the classroom. For the numeric method we used programme package Ansys Workbench 11.0 for building up three- dimensional model of the place with networking and Ansys CFX 11.0 for analysis and result display. At last we compared given results and defined if a numeric method is reliable enough to be used for displaying an actual state of the classroom.
