Kukanja, Aljaž (author), Arkar, Ciril (mentor), Medved, Sašo (comentor)

V nalogi je predstavljen teoretični model dinamičnega toplotnega odziva stavbe, kot ga opredeljuje standard SIST EN ISO 52016-1. Model združuje energijske bilance gradnikov in notranjega okolja v stavbi v urnem časovnem intervalu. Bilance gradnikov so izdelane z upoštevanjem v naprej opredeljenih porazdelitev toplotne kapacitivnosti. Razvito je bilo računalniško orodje za celoletno vrednotenje potrebne toplote in hladu za ogrevanje in hlajenje stavbe. Računalniško orodje je bilo verificirano na nivoju nestacionarnega prenosa toplote v gradnikih ovoja stavbe z orodjem TRNSYS. V delu je prikazana tudi primerjava rezultatov razvitega orodja s testnimi primeri iz SIST EN ISO 52016-1, standarda ASHRAE 140, kakor tudi rezultati simulacij toplotnega odziva stavbe s programskim orodjem TRNSYS.

Abstract

This diploma presents a theoretical model of dynamic thermal building response, as defined by the SIST EN ISO 52016-1 standard. The model combines energy balance of the building blocks and the interior environment in the building in an hourly interval. Energy balance of building blocks are constructed by taking into account the predefined distribution of thermal capacitance. A computer program for year-round evaluation of necessary heat and cooling for the heating and cooling of the building was developed. The program was verified at the level of non-stationary heat transfer in the building blocks of the building with the TRNSYS software. This diploma also shows the results comparison from the developed software using test cases from SIST EN ISO 52016-1, the ASHRAE 140 standard, as well as the results from the simulations of building heat response with the TRNSYS software.
