Abstract:Diplomsko delo opiše trenutno stanje na področju daljinskega ogrevanja in njegovih generacij ter raziskuje možnosti vključevanja obnovljivih virov energije v sistem daljinskega omrežja ob znižanju temperaturnega režima v sistemu. Opisane so potrebne spremembe za začetek uporabe 4. generacije daljinskega ogrevanja na strani proizvajalcev toplote in odjemalcev, načini shranjevanja toplote, s preračunom pa je ugotovljen vpliv znižanja temperature na toplotne izgube in pretoke, slednji se zaradi nižje temperature povečajo, zmanjšajo pa se toplotne izgube cevovoda. Z znižanjem temperaturnega režima je možno v sistem vključiti tudi toplotne črpalke, nižje temperature pa pozitivno vplivajo na COP število.
Keywords:daljinsko ogrevanje, generacije sistemov daljinskega ogrevanja, alternativni viri energije, znižanje temperaturnega režima, vpliv na toplotne izgube.

Title:Directions of development and use of efficient district heating with a high share of renewable energy sources
Abstract:The thesis describes the current state of the art in district heating and its generation and explores the possibilities of integrating renewable energy sources into the district grid system when the temperature regime of the system is reduced. It describes the necessary changes for the start of the 4th generation of district heating on the side of heat producers and consumers, the heat storage methods, and the impact of the temperature reduction on heat losses and flows, which increase due to the lower temperature and reduce the heat losses of the pipeline, is determined by a calculation. By lowering the temperature regime, heat pumps can also be integrated into the system, and lower temperatures have a positive effect on the COP number.
Keywords:district heating, generations of district heating systems, alternative energy sources, lowering the temperature regime, impact on heat losses.
