20.500.12556/RUL-185803 Moderni betoni za doseganje energetsko učinkovitih zgradb Modern concretes for achieving energy-efficient buildings V povezavi z energijo, trajnostno družbo in potrebo k zelenem prehodu, najdemo težavo za prihodnost in sicer imamo velik problem porabe fosilnih goriv in elektrike za delovanje klimatskih naprav in ogrevanje prostora, kar lahko rešimo z nadomeščanjem z materiali za shranjevanje energije. Najbolj primerni bi bili materiali za latentno shranjevanje energije. Moderne betone za doseganje energetsko učinkovitih zgradb tesno povezujemo z dodatkom fazno spremenljivih materialov (angl. phase change materials – PCM) betonu. Osredotočamo se torej na dodatek organskih fazno spremenljivih inertnih materialov betonu. Imamo tri tipe PCM materialov. Organske, anorganske in soli oziroma evtektične mešanice. Primerni bi bili organski PCM materiali, kot so voski ali parafini, ki imajo temperaturo tališča v temperaturnem območju notranjih prostorov zgradb. Te bi lahko enkapsulirali, torej jih zapakirali v votle kroglice s srajčko iz poliamida. Organski materiali so gorljivi, zato moramo biti pozorni na obnašanje materiala in sproščanje različnih plinov v primeru požara. Regarding energy, sustainable society, and the need for a green transition, we face a problem for the future, namely, we have a major problem with the consumption of fossil fuels and electricity for operating air conditioning and heating, which can be solved by replacing them with energy storage materials. The most suitable would be materials for latent energy storage. We closely link modern concretes for achieving energy-efficient buildings with the addition of phase-change materials (PCM) to concrete. We are focusing on adding organic phase – change inert materials to concrete. We have three types of PCM materials. Organic, inorganic, and salts or eutectic mixtures. Organic PCM materials, such as waxes or paraffins, which have a melting point in the temperature range of indoor spaces of buildings, would be suitable. These could be encapsulated, i.e., packaged in hollow balls with a polyamide sleeve. Organic materials are flammable, so we must be aware of the behavior of the material and the release of various gases in the event of a fire. beton latentna toplota PCM voski enkapsulcija concrete latent heat storage PCM waxes encapsulation true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2026-08-20 14:30:26 2026-08-20 14:30:37 2026-08-21 04:30:29 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 25576 Zver_racic_Nika_-_Moderni_betoni_za_doseganje_energetsko_ucinkovitih_zgradb.pdf Zver_racic_Nika_-_Moderni_betoni_za_doseganje_energetsko_ucinkovitih_zgradb.pdf 1 66B644A9E2CEA4675AA52C875ABA2000 7fce6cc423ff767668791ceaadb191258fbca46d7aed36e968362d7a36916f77 8fecea92-9c92-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=244785 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
