SUSTAV GRIJANJA STAMBENE ZGRADE TEMELJEN NA PRIMJENI OIE-A

U radu je napravljena analiza potrošnje primarne energije i emisije CO2 za višestambenu zgradu u Splitu. Analiza je napravljena u cilju utvrđivanja najpovoljnijega sustava grijanja. Uspoređena su četiri različita sustava grijanja, od kojih se dva temelje na iskorištavanju fosilnih goriva, a dva na iskorištavanju obnovljivih izvora energije. Na temelju proračuna potrošnje primarne energije, emisije ugljikova dioksida i ekonomičnosti za četiri različite izvedbe sustava ustanovljeno je da je najprihvatljiviji sustav grijanja na kompresijsku dizalicu topline. Razmatranjem sustava grijanja i pripreme potrošnje tople vode s toplovodnim kotlom na drvne pelete i sunčanim toplinskim kolektorima, s kompresijskom dizalicom topline zrak-voda, s kondenzacijskim kotlom na ekstra-lako loživo ulje te s kondenzacijskim kotlom na prirodni plin utvrđeno je da sustav grijanja na dizalicu topline, iako ima veću potrošnju primarne energije i emisiju CO2 od sustava grijanja na drvne pelete sa sunčanim toplinskim kolektorima, optimalno rješenje za promatranu zgradu.Termal losses analyse of multi-unit residential building in Split has been made in this paper. According to the calculated heat balance, the radiators of each room are dimensioned. The sistem analyses is done because of comparison of four different heat sistems, two of them are based on the exploitation of fossil fuels and other two are based of renewable energy sources. Based on the calculation of primary energy consumption, carbon dioxide emissions and cost-effectiveness for the four different performance of the system it was found that the most acceptable heating system is heat pump. Considering the heating system and preparation of hot water supply with a hot water boiler on wood pellets and solar thermal collectors, with compression air-to-water heat pump, a condensing boiler with extra-light fuel oil and a condensing boiler with natural gas, it was determined that the heating system with heat pump. even though it has higher primary energy consumption and CO2 emission than heating systems on wood pellets with solar thermal collectors, an optimal solution for these heating systems
