20.500.12556/RUL-108929 Gibanje zraka v kabini osebnega vozila Air movement in a car cabin Dolgi potovalni časi so vse bolj pogosti, s tem pa postaja toplotno ugodje v kabini osebnega vozila eden najpomembnejših vidikov ugodja med vožnjo pri vseh spremenljivih vremenskih pogojih. S pomočjo vročežičnih anemometrov je bila izmerjena lokalna hitrost in temperatura zraka v vozilu Nissan Micra, ter določena kategorija toplotnega okolja. V njem je bila z metodo infrardeče termografije opravljena vizualizacija toka zraka iz zračnikov. Med eksperimentom je bilo težko doseči konstanto temperaturo zraka zaradi ročne klima naprave, ki temperature ne nadzoruje in tako svojega delovanja ne more avtomatsko prilagajati. Thermal comfort is one of the most important factors regarding feelings of comfort experienced by humans in a vehicle cabin. Even more so with increasing time spent on roads and different thermal loads it is exposed to. In the experimental part of the Final thesis we measured local air temperatures and velocities in Nissan Micra interior, with the use of two hot wire anemometers. Indoor environment category was also determined for the aforementioned cabin. Method of infrared thermography was used for visualization of non-isothermal air flow out of a rectangular vent. During the experiment the air temperature had to be held constant, which was hard to achieve with a manual air conditioning system. toplotno ugodje prepih turbulenca gibanje zraka infrardeča termografija thermal comfort draught turbulence air movement infrared thermography true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2019-08-07 14:15:43 2019-08-07 14:15:47 2023-10-24 10:32:49 0000-00-00 00:00:00 2019 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 214731 3743.pdf 3743.pdf 1 0D256E3AA9ADBBC9A6C56E1C04B3DCAE d5bd51c099417dfa389ef58a904b04964bda257bd9cdf99f754e00f9bd15336c beb9c511-a1b6-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=120059 Fakulteta za strojništvo 0 0 0
