Abstract

V diplomskem delu je predstavljeno področje hranilnikov toplote, njihove fizikalne osnove in medsebojne primerjave. Obravnava je osredotočena predvsem na uporabo fazno spremenljivih snovi pri ogrevanju in hlajenju. Evropska unija si prizadeva doseči energetske in podnebne cilje s prenovo stavbnega sektorja z energetsko učinkovitejšimi sistemi ter z osredotočenjem na rabo obnovljivih virov energije. Le-to bi posledično omogočilo, da maksimalni dvig globalne temperature ne bi presegel 2 kelvinov do leta 2030. Do izziva pri uporabi obnovljivih virov energije pride, kadar sta proizvodnja energije in potreba po njej časovno neusklajena. Z vključitvijo hranilnikov toplote v sistem, ki izrabljajo obnovljive vire energije, je mogoče izravnati neskladje med proizvodnjo in potrebo po ogrevanju ali hlajenju stavb. Shranjevanje toplote ali hladu v latentnih hranilnikih omogoča učinkovito rabo obnovljivih virov energije zaradi možnosti shranjevanja velike gostote energije med fazno spremembo, kar pa zagotavlja tudi veliko gostoto energije pri majhnih temperaturnih razlikah.

Secondary title: Experimental research of latent heat storage
Secondary abstract: The thesis presents the field of heat storage tanks, their fundamentals and mutual comparison. The focus is on the use of phase change materials in heating and cooling. The European Union strives to achieve energy and climate goals with endeavour to renovate its building sector by giving priority to energy efficiency as well as considering deployment of renewable energies in order to secure global temperature increase below 2 K until 2030. The challenge in utilizing renewable energy sources is in its time unsteadiness when mismatch between production and demand occurs. With thermal storage integration into system that utilize renewable energy source it is possible to levelize mentioned mismatch between production from renewables and demand for heating or cooling of buildings. Thus thermal storage allows efficient utilization of renewable energy sources where among different materials of storing energy in heat or cold, phase change materials have advantage of having higher energy density at the small temperature difference.
