Abstract
U ovom radu analizirane su mogućnosti povećanja energetske učinkovitosti sustava grijanja zgrade i pripreme potrošne tople vode integriranjem elemenata za iskorištavanje sunčeve energije. Na temelju sustava grijanja stambene zgrade u Rijeci, izvedeni su proračuni za dimenzioniranje i odabir dijelova sustava. Izračunati su toplinski gubici koristeći arhitektonske i meteorološke podatke, što je poslužilo za dimenzioniranje podnog grijanja s temperaturnim režimom 42/35 °C i tri razdjelnika, po jedan za svaku etažu. Odabrani su Daikin Altherma hydro-split sustavi dizalica topline. Predložene su nadogradnje za povećanje energetske učinkovitosti, uključujući sustave solarnih kolektora za smanjenje potrebnog učina dizalice topline i fotonaponske elektrane za smanjenje troškova električne energije. Analize su pokazale da je isplativost sustava sa solarnim kolektorima niska jer bi povrat investicije trajao više od 25 godina. Sustav s kombinacijom solarnih kolektora i fotonaponske elektrane isplativ je nakon 25 godine, a sa sufinanciranjem nakon 9 godina. Preporučena je izvedba sustava s fotonaponskom elektranom, s povratom investicije nakon 13 godina, odnosno 6 godina sa sufinanciranjem, čineći ga najisplativijom opcijom.
Abstract (english)
In this paper, the possibilities for increasing the energy efficiency of a building's heating system and domestic hot water preparation by integrating elements for harnessing solar energy were analyzed. Based on the heating system of a residential building in Rijeka, calculations were performed for the dimensioning and selection of system components. Heat losses were calculated using architectural and meteorological data, which served as a basis for dimensioning the underfloor heating system with a temperature regime of 42/35 °C and three distributors, one for each floor. Daikin Altherma hydro-split heat pump systems were selected. Upgrades to increase energy efficiency were proposed, including solar collector systems to reduce the required output of the heat pump and photovoltaic power plants to reduce electricity costs. Analyses showed that the cost-effectiveness of systems with solar collectors is low, as the return on investment would take more than 25 years. A system combining solar collectors and photovoltaic power plants is cost-effective after 25 years, and with co-financing, after 9 years. The recommended system design includes a photovoltaic power plant, with a return on investment after 13 years, or 6 years with co-financing, making it the most cost-effective option.
