Modeliranje in simulacija toplotnih izgub stavbe

PRODAN, ROK (author), Zimic, Nikolaj (mentor)

Energetsko učinkovita poraba energije v stavbah za potrebe ogrevanja, ohlajevanja ter prezračevanja bo v prihodnje zaradi želje po energetski neodvisnosti in nuje po zmanšanju s tem povezanih stroškov predstavljala eno od glavnih raziskovalnih področij. Iskanje množice rešitev, ki bi pripeljale do optimalne porabe energije na realnem primeru stavbe, je dolgotrajen, zahteven, predvsem pa drag postopek. Za premagovanje tega problema je v tem diplomskem delu predstavljen in razvit poenostavljen toplotni model stavbe. Ta je bistven pri napovedovanju potreb po ogrevanju ali hlajenju, za spremljanje porabe energije ter razvoju in analizi raznih načinov ogrevanja in hlajenja. V nadaljevanju so bile izvedene simulacije različnih načinov ogrevanja in hlajenja na implementiranem matematičnem modelu stavbe. Na koncu so bili predstavljeni rezultati simulacij obdobja enega tedna iz testnega referenčnega leta v zimskem in poletnem času.

Abstract

Energy efficient use in buildings for heating, cooling and ventilation purposes is going to represent one of the main research areas in incoming years. Mainly because of the desire for energy independence as well as necessity for costs reduction. Seeking for a set of solutions which would lead to optimal energy consumption on real building case is time consuming, complex and especially cost ineffective process. To overcome this problem a simplified building thermal model is presented and developed in this thesis. This model is essential in predicting heating and cooling requirements for performance monitoring as well as for heating and cooling methods development and analysis. Several different heating and cooling methods were then simulated on the implemented mathematical building model. Finally simulation results for a time frame of one week in winter and summer seasons from a test reference year were presented.
