20.500.12556/RUL-146831 Izračun shranjene energije v aktivno-pasivnem sistemu plošč s fazno spremenljivimi snovmi na podlagi meritev Calculation of stored energy in the active-passive system of plates with phase change material based on measurements V diplomskem delu je bil predstavljen eksperimentalni sistem s fazno spremenljivimi snovmi (PCM), namenjen hlajenju prostora v poletnem času. PCM plošče služijo kot stabilizatorji temperature v stavbnem ovoju in preprečujejo pregrevanje stavbe. V eksperimentalnem delu smo določili čas, potreben za popolno strditev PCM-jev v ploščah, ter analizirali vse vplive na hladilno energijo. Ugotovili smo, da je sistem zadovoljiv le pri povprečni temperaturi vpihanega zraka 15 °C, ko so se PCM plošče strdile v 5,43 urah. Rezultati so pokazali, da je hladilna energija zelo odvisna od temperature vpihanega zraka ter zunanjih vplivov. This thesis presents an experimental system utilizing phase change materials (PCMs) for cooling indoor spaces during the summer. PCM panels serve as temperature stabilizers within the building envelope, effectively preventing overheating. The experimental work focused on determining the time required for complete solidification of PCMs in the panels and analyzing all influences on cooling energy. It was found that the system performed satisfactorily only when the average inlet air temperature was 15 °C, resulting in PCM solidification within 5.43 hours. The results demonstrated that cooling energy was highly dependent on the inlet air temperature and external influences. fazno spremenljive snovi latentni hranilniki toplote zmanjševanje pregrevanja prezračevana zračna reža shranjevanje toplotne energije zmanjševanje rabe energije phase change material latent heat storage reducing overheating ventilated air gap thermal energy storage reducing energy consumption true false false [D.
