20.500.12556/RUL-171242 Analiza sezonskega zalogovnika toplote s solarnim sistemom za ogrevanje objektov s programom TRNSYS Analysis of a seasonal thermal storage tank with a solar system for building heating using TRNSYS program Magistrska naloga obravnava sisteme sezonskega shranjevanja energije, primerne za zadostitev potreb po ogrevanju stavbnega objekta skozi leto. Predstavljene so vrste zalogovnikov toplote in opredelitev izbire uporabljenega zalogovnika. S pomočjo programskega orodja TRNSYS smo izvedli simulacije. Naredili smo pregled člankov, kjer se je kot optimalna izbira v našem primeru izkazal Type 342. V programu TRNBuild smo definirali cono, s pomočjo katere smo popisali termično obnašanje naše stavbe. Izvedeni sta bili dve vrsti simulacij potreb energije za ogrevanje. Prva je simulirala osnovne potrebe po ogrevanju stavbe brez zalogovnika toplote. Druga pa je simulirala potrebe po ogrevanju stavbe, pri kateri smo imeli na eni strani polnjenje sistema s senzibilnim zalogovnikom toplote in sprejemniki sončne energije, na drugi strani pa praznjenje, kjer smo ogrevali stavbo preko talnega gretja s shranjeno energijo iz zalogovnika. Rezultate, dobljene s programom, smo nato optimizirali iz tehničnega in ekonomskega vidika in tako prišli do optimalnih velikosti zalogovnika toplote in sprejemnikov sončne energije. Pri tehničnem vidiku smo upoštevali največjo pokritost potreb po ogrevanju sistema, ki je še smiselna. Za ekonomski vidik smo naredili optimizacijo z upoštevanjem povračila investicije sistemov različnih velikosti. Delo na koncu primerja rezultate iz obeh vidikov, jih ovrednoti in podaja smernice za nadaljnje delo. The master's thesis addresses seasonal energy storage systems suitable for meeting the heating demands of a building throughout the year. Different types of thermal storage systems are presented, along with an explanation of the selection of the specific storage solution used. Simulations were conducted using the TRNSYS software tool. A review of scientific articles was carried out, which identified Type 342 as the optimal choice for our case. In the TRNBuild module, we defined a zone that enabled us to describe the thermal behavior of our building. Two types of energy demand simulations for heating were performed. The first simulated the basic heating needs of the building without a thermal storage unit. The second simulation modeled the heating needs of the building using a system with a sensible heat storage unit and solar collectors on the input side, and a discharge system that provided space heating through underfloor heating using the stored energy. The results obtained from the program were then optimized from both technical and economic perspective, allowing us to determine the optimal sizes of the thermal storage unit and the solar collectors. The technical analysis considered the maximum feasible coverage of the heating demand by the system. For the economic perspective, optimization was carried out by evaluating the return on investment for systems of different sizes. Finally, the thesis compares the results from both perspectives, evaluates them, and provides recommendations for future work. sezonsko shranjevanje energije zalogovnik toplote TRNSYS simulacije model stavbe pokritost ogrevalnih potreb tehnično-ekonomska analiza seasonal energy storage thermal energy storage TRNSYS simulations building model coverage of heating demand technical-economic analysis true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2025-08-21 08:30:49 2025-08-21 08:30:57 2025-08-22 04:12:46 0000-00-00 00:00:00 2025 0 0 XXII, 85 str. 2025 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 697.329:536.24:004.94(043.2) 274502 246167299 43020.pdf 43020.pdf 1 45F53A4244AB44583BD349A8CC4C8151 53c245b7fbf52770921cfcf720fbe055649467a8f8df43ead6a841212e678a91 4b4ab3a8-7e58-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=214433 Fakulteta za strojništvo 0 0 0
