SOLAR ENERGY AIDED HOUSE HEATING

Diplomska naloga opisuje izrabljanje sončne energije za podporo ogrevanju hiše. V nalogi so podrobneje predstavljene teoretične osnove sončnega obsevanja in sprejemnikov sončne energije ter postopek, s katerim smo izračunali dnevno potrebo po toploti. Na podlagi več letnih podatkov o dnevnem obsevanju, smo izračunali za našo lokacijo optimalen naklon sprejemnika, s katerim bi pridobili v hladnejših mesecih, ko bi ogrevali prostore, največjo možno količino toplotne energije. Po izračunu pridobljene toplotne energije z vakuumskimi sprejemniki, je predstavljena ekonomska analiza projekta, s katero smo ugotovili, da se takšna podpora ogrevalnemu sistemu, zaradi trenutno drage začetne investicije, izplača hišam z nizkimi toplotnimi izgubami.Thesis describes the exploitation of solar energy to support the heating of the house. In the diploma we represent the theoretical basics of solar irradiation and solar receivers in more detail. Then we describe the procedure with which we calculated the daily heat (energy) needed for heating. On the basis of several years daily irradiation data, we calculated for our location an optimal angle of the receiver, which would gain the maximum possible amount of thermal energy in heating season (colder months, when we would be heating rooms). After the calculation of the obtained heat energy from the vacuum receivers, we represent the economic analysis of the project, in which we have come to the conclusion that such sort supported heating system is profitable only for the houses with low level of thermal losses, due to the current expensive initial investment
