Abstract

U ovome radu proveden je proračun za solarni toplovodni sustav čija je namjena priprema potrošne
tople vode (PTV) i grijanje prostora u višestambenoj zgradi gotovo nulte energije smještenoj u
klimatskom području Zagreba. Sustav je dimenzioniran tako da prikupljena toplinska energija
pokrije 30% ukupnih godišnjih energetskih potreba zgrade, vodeći računa da period povrata
investicije bude najmanji mogući. Algoritam proračuna proveden je prema satnoj metodi iz norme
za proračun solarnih toplovodnih sustava HRN EN 15316-4-3:2017 i normi za dinamički proračun
spremnika tople vode HRN EN 15316-5:2017 prema Metodi B u kojoj je spremnik podijeljen na
jedan volumni dio. Obije metode su detaljno objašnjene te je provedena analiza dobivenih
rezultata. Na kraju su dobiveni rezultati uspoređeni sa rješenjima dobivenim u računalnom
programu MGIPU Energetski certifikator.

Abstract (english)

Optimization of solar system whose purpose is preparation of hot water and heating the living
space of an apartment building with near zero energy placed in climate area around Zagreb is
carried out in this bachelor`s thesis. Solar system is designed in such a way that gathered solar
energy covers at least 30 % of overall yearly energy needs of the buiding`s residents, while taking
into account of the length of return on investment period. Algorithm, by which the optimization is
made, is conducted according to hourly method taken from the norm HRN EN 15316-4-3:2017
and from the method B from the norm, for calculation of constantly changing temperatures within
the hot water storage tank, HRN EN 15316-5:2017. Both methods are thoroughly explained and
analysis of the results is conducted. In the end, obtained results are compared with solutions that
are provided by MGIPU energy certifier computer program.
