Thermal energy storage plays a key role in the application of renewable energy sources and it thus contributes to the reduction of global COsub2 emissions. Thermal energy storage is commonly based on the sensible- or latent-heat-storage techniques. Latent-heat thermal storage is based on the absorption or release of heat when a storage material is changing phase. The thermal-storage materials suitable for latent-heat storage are called Phase-Change Materials (PCMs). PCMs have considerably higher thermal-energy-storage densities than the sensible-heat-storage materials and they are able to absorb large quantities of energy in a small range of temperatures during the phase change. Nowadays, micro-encapsulation of phase-change materials is one of the promising approaches in the integration of latent-heat storage in various applications. The most important properties of a latent-heat-storage medium are the heat of the fusion and the temperature range of the phase change. The correct determination of the physical and chemical properties is essential for a practical use of phase-change materials. The paper deals with the results of a laboratory assessment of the selected micro-encapsulated PCMs and shows a practical example of a possible integration in the building structures"},{"@xml:lang":"sl","#text":"Delovanje nizkoenergijskih pasivnih hiš lahko temelji na uporabi aktivne ali pasivne uporabe obnovljivih energijskih virov. Shranjevanje toplotne energije igra ključno vlogo pri uporabi obnovljivih virov energije in zato vpliva na zmanjšanje globalne emisije COspodaj2. Shranjevanje toplotne energije navadno temelji na smiselnih tehnikah ali tehnikah shranjevanja latentne toplote. Shranjevanje latentne toplote temelji na absorpciji ali sproščanju toplote, ko material za shranjevanje spreminja fazo. Materiale, ki so primerni za shranjevanje latentne toplote, imenujemo materiali s fazno premeno (PCM). PCM imajo občutno višjo gostoto za shranjenje toplotne energije v primerjavi z občutljivimi materiali za shranjevanje toplote in so sposobni absorbirati med fazno premeno večjo količino energije v manjšem temperaturnem intervalu. Dandanes je vgradnja mikroenkapsulacijskih materialov s fazno premeno obetajoča za številne možnosti uporabe. Najpomembnejši lastnosti medija za shranjevanje latentne toplote sta talilna toplota in temperaturno področje fazne premene. Pravilno določanje fizikalnih in kemijskih lastnosti je bistveno za praktično uporabo materialov s fazno premeno. Ta članek obravnava laboratorijsko oceno izbranih PCM in kaže praktičen primer možnosti njihove uporabe v gradbeništvu"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:DOC-QFZ6RBWS","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-QFZ6RBWS"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-QFZ6RBWS/dd24dbab-2f9d-43d1-95b8-af98cce21f44/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Inštitut za kovinske materiale in tehnologije"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:DOC-QFZ6RBWS/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-QFZ6RBWS"}}}}
