20.500.12556/RUL-119450 Testiranje visoko učinkovitih filtriranih sistemov v industrijskih obratih In situ test for high efficiency filter systems in industrial facilities Diplomska naloga obravnava tematiko validiranja visoko učinkovitih filtrov vgrajenih v sistem odvodne filtracije. Visoko učinkovit filter je pomemben pri zagotavljanju kakovosti zraka, saj lahko mikroskopsko majhni delci v zraku povzročijo težave z zdravjem ljudi ali kakovostjo proizvodov. V prvem delu diplomske naloge so predstavljeni mednarodni standardi, ki zajemajo testne metode in kriterije sprejemljivosti po vgradnji filtra v prezračevalni sistem. V drugem delu je prikazan potek validacije z optičnim števcem delcev. Prikaz je narejen na primeru vzorčenja s statičnimi sondami in na primeru prototipa skeniranja filtra. Meritev je bila izvedena na odvodnem sistemu s kanalsko filtracijo stopnje filtracije H13. V zaključku je izračunana učinkovitost celotne in lokalne filtracije pri referenčnem delcu velikosti 0,3 mikrometra. The topic of the thesis is the validation of highly efficient filters built into the ventilation filtration system. The HEPA and ULPA filters are important in ensuring air quality, as microscopically small particles in the air can cause health issues or product quality problems. The first part of the thesis presents international standards, which include test methods and acceptability criteria after the installation of the filter into the ventilation system. The second part shows the validation process with an optical particle counter. The case is made on the example of sampling with static probes and on the example of a prototype filter scan. The measurement was performed on the exhaust ventilation system with a duct filter unit of the H13 filtration class. In the conclusion the efficiency of total and local filtration is calculated at a reference particle size of 0,3 micrometres. odvodni zrak HEPA filter filtracija integritetni test učinkovitost filtracije optični števec delcev čisti prostori exhaust air HEPA filter filtration integrity test filtration efficiency optical particle counter cleanroom true false false [R.
