20.500.12556/RUL-95547 Analiza adsorpcijskega shranjevalnika toplote Analysis of heat storage system Namen zaključne naloge je pregled shranjevanja toplotne energije in pridobivanja le – te iz obnovljivih virov. Osredotočili smo se na do sedaj najmanj raziskano področje – to je termokemično shranjevanje toplotne energije. Cilj je raziskati prenos toplote in snovi v poroznem mediju, ki adsorbira nasičeno vodno paro. Za raziskavo je bil izbran porozen medij silikagel. Zanimale so nas lastnosti poroznega medija, na kakšen način lahko v shranjevalniku toplotno energijo sploh hranimo in kakšne so njegove slabosti. Prav tako smo si zastavili cilje, da bi že obstoječe meritve in analize v prihodnosti primerjali z rezultati, ki bi jih pridobili s pomočjo programov kot so ANSYS Fluent ali Comsol. Na ta način bi lahko lažje prišli do analiz, prav tako pa bi že s simulacijo lahko preverili, na kaj moramo biti pazljivi pri optimiziranju in sestavljanju prototipa. The purpose of the final thesis is to review the storage of thermal energy and its extraction from renewable sources. Our focus has been on the least reasearched area until now – thermochemical storage of heat energy. The aim of the paper is to investigate the mass and heat transfer in a porous medium that absorbs saturated water vapor. For the study, a porous silica gel medium was selected. We were interested in the characteristics of the porous medium, in what way can thermal energy be stored in a thermal energy storage unit, and what are its weaknesses. We have also set goals to compare the already existing metrics and analyzes with the results that would be obtained through programs such as CFD Fluent or Comsol in the future. In this way, it would be easier to get to analyzes while – with the help of a simulation – we could check what we should be careful about when optimising and composing the prototype. shranjevalnik toplote vodna para adsorpcija porozni medij obnovljivi viri energije heat storage water vapor adsorption porous medium renewable energy true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2017-09-20 14:56:55 2017-09-20 14:56:55 2023-10-24 08:32:35 0000-00-00 00:00:00 2017 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 201369 1274.pdf 1274.pdf 1 9312E1A7A43F11A4F694B1CD385E4221 acfb9c7fd8c94ec3807ec7dcbdd6fe0df084cdbbf801b83c5eb28a6df25d8fda c881f457-a1b3-11eb-a523-00155dcfd717 20.500.12556/rul/6968e6a1-88e0-4638-a799-5d90e80905b4 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=104153 Fakulteta za strojništvo 0 0 0
