20.500.12556/RUL-172724 Razvoj eksperimentalno validiranega pol-empiričnega modela za napovedovanje delovanja toplotne črpalke Development and experimental validation of a semi-empirical model for the prediction of heat pump performance Zaključna naloga obravnava razvoj in validacijo pol-empiričnega modela za napovedovanje delovanja toplotne črpalke, ki deluje na osnovi parno-kompresijskega cikla. Postavljena je bila eksperimentalna proga, kjer smo lahko beležili podatke o delovanju toplotne črpalke, kot so temperatura dvižnega in povratnega voda, tlak kondenzacije in uparjanja, pretok sekundarnega medija in električno porabo. Model smo preverili z meritvami na realnem sistemu izboljšane toplotne črpalke zrak-voda. Eksperimentalna validacija je potrdila ustreznost modela, saj je ujemanje med modelom in eksperimentalnimi rezultati znotraj ± 10 %. Model tako služi kot osnova za snovanje štirih glavnih komponent toplotne črpalke – kompresorja, kondenzatorja, uparjalnika in elektronskega ekspanzijskega ventila – pri razvoju novih ter optimizaciji obstoječih modelov toplotnih črpalk. The thesis addresses the development and validation of a semi-empirical model for predicting the performance of a heat pump operating based on the vapor-compression cycle. An experimental column was set up, allowing the recording of operational data such as supply and return water temperatures, condensation and evaporation pressures, secondary fluid flow rate and electrical power consumption. The model was verified through measurements on a real air-to-water heat pump system. Experimental validation confirmed the suitability of the model, as the agreement between the model predictions and the experimental results was within ± 10%. The model therefore serves as a basis for the design of the four main components of a heat pump – the compressor, condenser, evaporator and electronic expansion vale – in the development of new systems as well as in the optimization of existing ones. toplotna črpalka parno-kompresijski cikel pol-empirični model eksperimentalna validacija heat pump vapor-compression cycle semi-empirical model experimental validation true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2025-09-11 08:32:11 2025-09-11 08:32:13 2025-10-20 04:00:42 0000-00-00 00:00:00 2025 0 0 XIX, 54 str. 2025 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 2026-09-08 621.577:550.34.016(043.2) 276003 249447171 44189.pdf 44189.pdf 1 5F39D43964803306FD37A808DC10FB64 732e82924a6aeb6f99d51a86e4a5ca2792879ece4c9ccc71de0681850fd89512 e4675561-8ed8-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=216754 Fakulteta za strojništvo 0 0 0
