Abstract
Diplomsko delo je študija prehoda toplote v treh izbranih detajlih Qbiss Air fasadnega sistema, ki ga proizvaja Trimo d.d. Ti detajli so: (A) bočni stik dveh fasadnih panelov v vogalu, ki gleda navznoter, (B) stik dveh fasadnih panelov v vogalu, ki gleda navzven ter (C) stik fasadnega panela s temeljno gredo. Narejene so ravninske numerične analize po metodi končnih elementov, s katerimi je simulirano prehajanje toplote skozi omenjene detajle pri stacionarnih pogojih. Pri pripravi računskih modelov je bil upoštevan standard SIST EN ISO 10211. Kompleksna geometrija vseh detajlov je z vsemi podrobnostmi pripravljena v programu Catia V5. Numerične analize so izvedene s programskim paketom Ansys 13.0, določene so bile tudi optimalne mreže končnih elementov. Na podlagi rezultatov numerične analize sta se za vsak detajl izračunala faktor linijskega toplotnega mostu (?) in temperaturni faktor toplotnega mostu (fRSi). Ti faktorji so podlaga za izračun toplotne prehodnosti (HT) za stavbe s fasado iz Qbiss Air elementov. Na koncu so na podlagi dobljenih rezultatov predlagane možnosti za morebitne izboljšave detajlov.

Title:Numerical analysis of heat transfer at the joints of Qbiss Air facade system
Abstract:
The thesis presents a study of heat transfer in three selected details of Qbiss Air façade system, produced by Trimo d.d. These details are as follows: (A) lateral contact of two façade panels in the corner, facing inwards, (B) contact of two façade panels in the corner, facing outwards and (C) the façade panel - foundation base junction. Two-dimensional numerical analysis using finite element method was used to simulate steady-state heat transfer at described junctions. Complex geometry of all details was designed using Catia V5 software ragarding to standard SIST EN ISO 10211. Numerical analyses were carried out using software package Ansys 13.0 and optimal finite element meshes of details were determined. Based on the results of numerical analysis, linear thermal transmittance (?) and temperature factor at the internal surface (fRSi) were calculated for each detail. These factors are the basis for the calculation of transmission heat transfer coefficient (HT) of buildings with Qbiss Air façade system. Based on the obtained results, possibilities for eventual future improvements of details were suggested.

Keywords:graduation thesis, design, thermal analysis, finite elements, Qbiss Air, linear thermal bridges, Ansys
