Abstract

V današnjem svetu zaradi globalnega ogrevanja in onesnaževanja okolja stremimo k čim nižji porabi energije. Poleg industrije in pometa se veliko energije porabi tudi za ogrevanje stavb, zato moramo poskrbeti, da se čim manj toplote iz notranjih prostorov izgubi v okolico. Zaključna naloga obravnava vplive različnih vrst oken na njihovo toplotno prehodnost. Cilj naloge je raziskati, kako lahko z izbiro različnih parametrov okna znižamo toplotne izgube in s tem prihranimo pri energiji. V teoretičnem delu so razloženi osnovni pojmi, ki se pojavljajo pri obravnavi problema prehoda toplote. Opisane so tudi različne komponente, ki jih vgrajujemo v okna, ter njihovi vplivi na toplotno prehodnost. Računski del obravnava primerjavo toplotne prehodnosti različnih kombinacij okenskih okvirjev in zasteklitev. Rezultati izračuna kažejo, da so vplivi nekaterih parametrov na toplotno prehodnost večji od vplivov drugih in je treba nanje v večji meri paziti pri nakupu oken.

Secondary title: Window heat transfer
Secondary abstract: Nowadays, we aim to lower energy consumption due to global warming and environment pollution of our planet. In addition to industry and traffic, a lot of energy is also used to heat the buildings, so we need to ensure that as less as possible of the indoor heat is lost to the environment. The thesis deals with the impacts of different types of windows on their heat transfer. The aim of the thesis is to investigate how, by selecting different window parameters, we can reduce heat losses and thereby save energy. The theoretical part explains the basic concepts that arise in dealing with the problem of heat transfer. It also describes the various components that are installed in the windows, and their effects on the heat transfer. The calculation part compares the heat conductivity of the various combinations of window frames and glazing. The results of the calculation show that the effects of some parameters on the heat conductivity are greater than the effects of others and that more attention should be paid to that when purchasing windows.
