A new parameter based on a relative decrease of tracer gas concentration in the first minute of system operation dC(1) was introduced. The newly defined parameter has been verified by simulation results from commercial computational fluid dynamics (CFD) software. The usefulness of the parameter is the possibility to make quick measurements of the local efficiency of personalized ventilation systems</dc:description><dc:description xml:lang="sl">Analizirali smo učinkovitost prezračevanja na prototipu sistema za lokalno klimatizacijo PERMICS (Personal Microclimate System) z uporabo sočasnih meritev hitrostnega polja ter polja koncentracij sledilnega plina z uporabo metode zmanjšanja koncentracije sledilnega plina. Pri tem je bil vpeljan in predstavljen nov parameter dC(1), ki temelji na relativnem zmanjšanju koncentracije sledilnega plina v prvi minuti delovanja sistema. Novo definirani parameter je overjen z rezultati opravljenih simulacij s tržnim paketom za računalnisko dinamiko tekočin (CFD).Uporabnost parametra dC(1) je v možnosti hitre izvedbe meritev lokalne učinkovitosti na sistemih lokalnega prezračevanja in klimatizacije</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:doc-KEUL2NG0"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:doc-KEUL2NG0" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:doc-KEUL2NG0/575cc4c5-8f03-492d-90c8-12afaf952925/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Univerza v Ljubljani, Fakulteta za strojništvo</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:doc-KEUL2NG0/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:doc-KEUL2NG0" /></ore:Aggregation></rdf:RDF>
