Abstract

U ovome radu prikazani su proračuni toplinskih gubitaka termotehničkog sustava za grijanje i pripremu potrošne tople vode prema novim prijedlozima normi iz serije prEN 15316. Prikazani su proračuni za podsustav predaje, podsustav razvoda, podsustav proizvodnje sa spremnikom toplinske energije i solarnim toplovodnim sustavom te na kraju proračun isporučene i primarne energije. Proračun je proveden za referentnu hrvatsku kuću prema mjesečnoj i satnoj (satna raspodjela za karakterističan dan svakog mjeseca) metodi. Rezultati proračuna dobiveni mjesečnom i satnom metodom uspoređeni su za svaki dio sustava. Također su prikazani i uspoređeni rezultati za klimatska područja Zagreba i Splita za zadanu potrebnu godišnju energiju za grijanje od 10 kWh/m² i 70 kWh/m². Na kraju rada, prikazane su moguće mjere uštede na primarnoj energiji te je izrađena troškovno optimalna analiza za period korištenja od 30 godina.

Abstract (english)

In this thesis the procedure for calculating heat losses of space heating and domestic hot water system according to draft standard series prEN 15316 is given. Calculations for emission, distribution generation, storage and solar sub-system are shown, as also the calculation of delivery and primary energy. Calculation example is given for a referent Croatian dwelling located in Zagreb and Split area with the defined energy need for heating of 10 kWh/m² and 70 kWh/m². Calculations are carried out on hourly and monthly basis and the obtained results of each sub-system are compared. At the end, possible measures of energy efficiency improvement are evaluated and cost-optimal analysis for period of 30 years is made.
