Abstract

Svrha ovog rada je proračun sustava podnog grijanja pri opskrbi stambenog prostora toplinskom energijom u svrhu ostvarivanja toplinske ugodnosti za vrijeme sezone grijanja. Naglasak je u radu stavljen na promjenu različitih parametara (visina betonske glazure, temperatura vode na polazu i brzina strujanja vode) te promatranje njihovog utjecaja na toplinska svojstva prostora. Pritom se ponajprije misli na proučavanje svojstava sustava koji koristi akumulaciju toplinske energije u masi betonske glazure koja značajno utječe na inerciju sustava grijanja. Proračun je, dakle, proveden za različite vrijednosti navedenih parametara te je prikazano kako oni djeluju na ponašanje sustava, primarno utroška toplinske energije i temperature zraka u prostoriji. Sam proračun, odnosno simulacija, izvršen je pomoću računalnog programa MATLAB, točnije u potprogramu Simulink. Oni su korišteni radi visoke razine interaktivnosti te mogućnosti vizualizacije pri obradi signala i prikazu rezultata simulacije pomoću potprograma Simulink.

Abstract (english)

The purpose of this thesis is the analysis of an underfloor heating system used for the purpose of supplying a living space with heat in order to achieve thermal comfort during the heating season. The emphasis of the thesis is put on alternating different parameters (concrete layer height, starting point water temperature and water speed) and observating their effect on thermal conditions inside the living space. The thesis mostly covers the observation of the properties of heat accumulation systems by simulating the process of heat accumulation using the thermal capacity of the concrete layer, which significantly influences the inertion of underfloor heating systems. The analysis was conducted using different values of the above mentioned parameters, and their effects on the system behaviour, primarily energy consumption and air temperature, are presented and explained. Behaviour of the underfloor heating system was simulated using the programming tool MATLAB, specifically its subprogram Simulink. MATLAB and Simulink were chosen due to their high level of interactivity and the ability of visualization during signal treatment and their result displaying abilities.
