20.500.12556/RUL-148472 Phase-change material thermal energy storage for the smart retrofitting of existing buildings This article presents the use of phase-change material (PCM) thermal storage within the Horizon 2020 HEART project (Holistic Energy and Architectural Retrofit Toolkit), aimed at decarbonising the European building sector through the retrofitting of existing structures into energy-efficient smart buildings. These buildings not only reduce energy consumption, but also incorporate advanced technologies for harnessing green energy, thereby promoting environmental sustainability. The HEART project employs state-of-the-art technologies for electricity production/dispatching and heat generation/storage, managed by a cloud-based platform for the real-time monitoring of parameters and optimising energy utilisation, enabling users to control their environmental comfort. The article provides a detailed examination of one of the project’s demonstration sites in Italy, focusing on various components such as heat pumps, photovoltaic systems (PV), controllers, and particularly emphasising the significance of storage tanks. The study involved the measurement and analysis of three heat storage tanks, each with a total volume of 3000 L. These tanks utilised PCM modules for latent heat storage, significantly enhancing overall heat accumulation. Water served as the heat transfer fluid within the tanks. Through meticulous calculations, the article quantifies the accumulated heat and presents a comparative evaluation between PCM-based storage tanks and conventional water tanks, showcasing the advantages of PCM technology in terms of increased heat retention and efficiency. energy renovation of the buildings heat pumps heat storage tanks phase-change materials energetska prenova stavb toplotne črpalke hranilniki toplote materiali s fazno zamenjavo true false true Angleški jezik Slovenski jezik Članek v reviji 2023-08-24 08:38:00 2023-08-24 08:38:03 2023-08-25 03:40:41 0000-00-00 00:00:00 2023 0 0 13 str. iss. 17, art. 6127 Vol. 16 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 620.9:697 1996-1073 10.3390/en16176127 162081795 Osterman_..._Phase-change_material_thermal_energy_storage_for_the_smart_retrofitting_....pdf Osterman_..._Phase-change_material_thermal_energy_storage_for_the_smart_retrofitting_....pdf 1 5948E120EEBDC8F2F165351C60CD92AC 7828796fe25d4de84840c922ec5fd219ecefbb72434b87ef6e18b5ffeebbda5c c048c662-4249-11ee-b9d7-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=172722 https://www.mdpi.com/1996-1073/16/17/6127 1 b91916b2-4248-11ee-b9d7-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=172721 Fakulteta za strojništvo 0 0 0
