Izračun dinamičnih toplotnih lastnosti gradbene konstrukcije

Žižak, Tej (author), Prek, Matjaž (mentor)

Dinamične toplotne lastnosti nam pokažejo odziv gradbene konstrukcije, ki je na zunanji strani izpostavljena (poenostavljeni) sinusni spremembi temperature v intervalu 24 ur. Gradbena konstrukcija v tej nalogi je stena iz poljubnega števila homogenih slojev. Za potrebe te naloge sem napisal program, ki izračuna dinamične toplotne lastnosti za steno iz poljubnega števila slojev. S pomočjo programa sem najprej prikazal vpliv posameznih parametrov na nekatere najbolj tipične dinamične toplotne lastnosti. Nato sem primerjal lastnosti izbranih 5 tipičnih sestav sten. Rezultati so pokazali znatno izboljšanje lastnosti stene z dodano izolacijo. Pri postavitvi izolacije je bolj učinkovita postavitev na zunanji strani stene.

• Title: Calculation of dynamic thermal characteristics of building component

Abstract

Dynamic thermal properties show us the response of the building component, which is exposed to the external (simplified) sinus temperature change in an interval of 24 hours. The construction structure in this task is a wall from any number of homogeneous layers. For the purposes of this task I wrote a program that calculates dynamic thermal characteristics for a wall of any number of layers. Using the program, I first showed the influence of individual parameters on some of the most typical dynamic thermal characteristics. Then I compared the properties of the selected 5 typical wall constructions. The results showed a significant improvement in the properties of the wall with added insulation. When installing the insulation, the installation on the outer side of the wall is more effective.
