CALCULATION OF HEAT LOSSES OF THE BUILDING AND PLANNING HEATING SYSTEM WITH SOLAR CELLS AND FUEL CELLS

Pomemben del gradnje in vzdrževanja objektov predstavlja izračun toplotnih izgub ter stroškov ogrevanja in načrtovanje ustreznega sistema ogrevanja. Ta naloga na konkretnem primeru obravnava postopek analitičnega izračuna toplotnih izgub določenega objekta in proučuje dolgoročen vpliv izolacije na stroške ogrevanja. V drugem delu obravnava zamišljen sistem ogrevanja s sončnimi in gorivnimi celicami, pri čemer je poudarek na slednjih. Predstavi probleme proizvodnje in skladiščenja vodika ter porabe v gorivnih celicah. Za obravnavani objekt so določeni osnovni parametri sistema in finančna ocena.Important part of constructing and maintaining buildings is calculation of heat losses and heating costs and planning appropriate heating system. This work deals with procedure of analytic calculation of heat losses of building and studies long-term influence of insulation on heating costs. For example are used plans of real building. The second part deals with heating system with solar and fuel cells. Problems of hydrogen production, storage, and using in fuel cells are presented. For building, used for example, basic parameters of system are calculated and financial evaluation is made
