Abstract (Croatian)

U ovom završnom radu je proračunat i projektiran sustav grijanja i pripreme potrošne tople vode stambene zgrade. Sustav grijanja predviđen je kao niskotemperaturni s dizalicom topline tlo-voda i s podnim grijanjem temperaturnog režima 35/30 °C. Proračun projektnih toplinskih gubitaka proveden je prema normi HRN EN 12831. Proračun godišnje potrebne toplinske energije za grijanje je proveden prema „Algoritam za proračun potrebne energije za grijanje i hlađenje prostora zgrade prema HRN EN ISO 13790“ na temelju kojeg je ova zgrada svrstana u pripadajući energetski razred. Podno grijanje je dimenzionirano prema dijagramima proizvođača na temelju izračunatih toplinskih gubitaka svake prostorije. Za pripremu potrošne tople vode predviđen je akumulacijski sustav sa bivalentnim spremnikom koji se zagrijava sa solarnim kolektorima, uz podršku dizalice topline i električnog grijača. Na temelju proračuna prema normi HRN EN 15316-4-3 preuzetoj iz „Algoritam za određivanje energijskih zahtjeva i učinkovitosti termotehničkih sustava u zgradama - Sustavi grijanja prostora i pripreme potrošne tople vode“, ukupna površina solarnih kolektora od je dovoljna za pokrivanje potrebne toplinske energije za pripremu potrošne tople vode od lipnja do kolovoza. Sustav grijanja i pripreme potrošne tople vode je opremljen sa svom armaturom i regulacijskim elementima potrebnim za potpuno automatski rad. U prilogu se nalaze crteži kojima se definira raspored opreme te funkcionalna shema spajanja i automatske regulacije.

Abstract

In this final work is calculated and designed the heating and domestic hot water systems of the residential building. The heating system is designed as a low-temperature with heat pump ground-water and with floor heating temperature regime 35/30 °C. Calculation of project heat losses was carried out according to standard HRN EN 12831. Calculation of annual heat energy use for heating is carried out according to "The algorithm for calculation of the necessary energy for heating and cooling the building according to EN ISO 13790" on the basis of which the building was classified in the corresponding energy class. Floor heating is dimensioned according to the manufacturer's diagrams on the basis of the calculated heat loss in each room. Floor heating is dimensioned according to the manufacturer's diagrams on the basis of the calculated heat loss in each room. Storage system for domestic hot water is designed as an accumulation system with bivalent tank which is heated with solar collectors, with the support of heat pump and electric heater. On the basis of calculations according to standard EN 15316-4-3 taken from "The algorithm for determining the energy requirements and efficiency of HVAC systems in buildings - Systems of heating and domestic hot water ", the total area of solar collectors is sufficient to cover the required heat for domestic hot water from June to August. The heating system and the system of domestic hot water is equipped with all the fittings and the regulatory elements necessary for fully automatic operation. Attached are drawings that define the layout of equipment, with functional scheme of merger and automatic regulation.
