Abstract

U radu je napravljen odgovarajući program u Microsoft Excel-u za izračun godišnje potrošnje isporučene i primarne energije potrebne za grijanje prostora i pripremu potrošne tople vode. Proračun je napravljen na temelju normi HRN EN 15316:2017 prema satnoj metodi, za karakterističan dan u mjesecu, za odabrani termotehnički sustav. Sustav se sastoji od podsustava predaje, razvoda, proizvodnje te spremnika PTV-a. Rezultati dobiveni proračunom prema novim normama uspoređeni su s rezultatima dobivenim u MGIPU Energetskom Certifikatoru, koji vrši proračune prema starijoj verziji normi. Također je napravljena i usporedba sa sustavom koji ne sadrži spremnik PTV-a, na temelju koje se mogu donijeti zaključci o utjecaju spremnika na dobivene rezultate.

Abstract (english)

In this thesis, an appropriate program was made in Microsoft Excel for calculating the annual consumption of delivered and primary energy needed for space heating and preparation of domestic hot water. The calculation was based on EN 15316: 2017 series of standards according to the hourly method for a characteristic day of the month, for the selected thermotechnical system. The system contains space emission and distribution sub-system, generation sub-system and storage water tank. The obtained results were compared with the results from MGIPU Energetski Certifikator, which gives results according to the older version of the standards. A comparison was also made with a system that does not contain a storage water tank. Based on the comparison, conclusion about the influence of storage tank was made.
