20.500.12556/DKUM-87225 Primerjava ogrevanja stanovanjske hiše na lesno biomaso in toplotno črpalko ter njihov vpliv na okolje master study programme Comparison of residental house heating with wood biomass and a heat pump and their environmental impact Magistrsko delo zajema preračun toplotnih obremenitev po standardu SIST EN 12831:2004, za katerega je določena notranja temperatura po standardu SIST EN ISO 7730 206. Na podlagi dejanske temperature okolice za območje objekta je po tehnični smernici o učinkoviti rabi energije določen časovno odvisen COP toplotne črpalke zrak–voda za tri kurilne sezone (2020/2021, 2021/2022 in 2022/2023). Primerjava izračunanih toplotnih obremenitev, ki upoštevajo projektno zunanjo temperaturo s toplotnimi obremenitvami, ki temeljijo na dejanskih temperaturah, je pokazala, da izračuni, ki temeljijo na projektni zunanji temperaturi, ne prikazujejo dejanske toplotne obremenitve objekta. Podana je primerjava porabe električne energije idealnega in dejanskega COP števila. Z izračunanimi vrednostmi toplotnih obremenitev je določena poraba lesne biomase, ki je primerjana s porabo električne energije pri uporabi toplotne črpalke. Zaradi števila COP je toplotna črpalka energetsko učinkovitejši sistem ogrevanja. Za dobljeno porabo obeh energentov so bile določene emisije. Primerjava emisij je pokazala, da ogrevanje z lesno biomaso v primerjavi z ogrevanjem s toplotno črpalko prispeva k manj CO2 in za uporabnika predstavlja nižji strošek. The master's thesis covers the calculation of heat loads according to the SIST EN 12831:2004 standard, for which the internal temperature is determined according to SIST EN ISO 7730 206 standard. Based on the actual temperature for the area of the building, according to the technical guideline on efficient energy use, a time-dependent thermal COP is determined for air-water heat pumps for three heating seasons (2020/2021, 2021/2022 and 2022/2023). A comparison of the calculated heat loads, that take into account the project outdoor temperature with the heat loads that are based on the actual temperatures, showed that the calculations based on the project outdoor temperature do not show the actual heat load of the building. Comparison is given of electricity consumption of the ideal and actual COP number. With the calculated values of heat loads, the consumption of wood biomass is determined, which is compared with the consumption of electricity when using a heat pump. Due to the COP number, the heat pump is a more energy efficient heating system. Emissions were determined for the resulting consumption of both energy sources. The comparison of emissions showed that heating with wood biomass contributes less CO2 and represents a lower cost for the user compared to heating with a heat pump. toplotna obremenitev električna energija lesna biomasa toplotna črpalka emisije heat loads electrical energy wood biomass heat pump emissions true true false [L.
