COMPARATIVE ANALYSIS OF HEATING WITH SELECTED HEAT PUMPS SYSTEMS

Diplomska naloga opisuje izračun toplotnih črpalk treh različnih sistemov izkoriščanja obnovljivih virov energije za ogrevanje pasivne hiše na podlagi izračunanih toplotnih izgub. Narejen je program, s katerim so izdelani izračuni za porabo eleketrične energije, toplotne moči, grelnega števila in obratovalnega časa toplotnih črpalk. Zbrani so stroški investicij v posamezne sisteme toplotnih črpalk, s katerimi je opravljena primerjalna ekonomska analiza. Na streho pasivne hiše je umeščena mikro sončna elektrarna, s katero je ocenjeno, ali lahko s proizvodnjo električne energije in prodajo te pokrijemo stroške porabe električne energije izbrane toplotne črpalke.Diploma work describes three different calculation’s models of renewable energy consumption by heat pumps. Calculations are based on passive house heating, including the heat loss factor. Programme for calculation of electrical energy consumption, heat power, coefficient of performance and operating time of heat pumps has been made. Investments costs of each heat pump system have been collected and economic comparison analysis was being elaborated. Furthermore, diploma work estimates the expenses of electrical energy consumption of specific heat pump in comparison with electrical energy obtained by solar power plant. For this purpose solar power plant was installed on the roof of the passive house
