Abstract

Solarni toplovodni sustavi se mogu koristiti za grijanje potrošne tople vode (PTV), prostora ili bazenske vode. U ovome radu su za početak opisani ti sustavi zajedno sa svojim osnovnim komponentama. Glavni cilj je bio dimenzionirati solarni toplovodni sustav za grijanje prostora i pripremu potrošne tople vode niskoenergetske obiteljske kuće. Pri tome se pazilo da prikupljena toplinska energija pokrije najmanje 30% ukupnih godišnjih energetskih potreba te da period povrata investicije bude najmanji. Proračuni potrebne i isporučene toplinske energije solarnog toplovodnog sustava su provedeni prema mjesečnoj i satnoj metodi norme HRN EN 15316-4-3:2017. Uz to se koristio i program MGIPU Energetski Certifikator u kojeg su se unijele dimenzije i karakteristike kuće. Tim računalnim programom se može provesti proračun cjeloukupne energetske bilance zgrade,a u ovome radu se najveća pažnja posvetila analizi podataka dobivenih za solarni sustav. Na kraju rada su prikazani i komentirani dobiveni rezultati ovih triju metoda proračuna.

Abstract (english)

Solar hot water systems can be used for heating of domestic water, space or swimming pool water. In this work is firstly given a description of solar hot water heating systems and their basic parts. The main goal was to size certain low-energy house solar DHW and space heating system. Task of the chosen solar system is to cover at least 30% of the house energy demands. The system must also have minimal payback period. Calculations have been performed according to the hourly and monthly method of the norm HRN EN 15316-4-3:2017. Besides that, dimensions and other house characteristics have been inputed into a computer program MGIPU Energetski Certifikator. This program has capability of calculating overall building energy balance.. For the purpose of this work, largest attention has been given to the solar system output values. Results of previusly mentioned calculating methods and computer program have been analysed and compared with each other.
