The construction of a refrigerating system that uses R22 and R407C is presented, along with measurements of all the relevant data (temperature, pressure and flow rate). their acquisition, and their analysis. Our results show that the refrigerant R407C is a good substitute for the refrigerant R22 at higher evaporation temperatures. Although the theoretical results suggest that R407C will increase efficiency compared to R22, the experimental results did not confirm it. This because in the process with the refrigerant R407C the heat-transfer coefficients are lower</dc:description><dc:description xml:lang="sl">Za sistem, ki deluje pri enakih pogojih je bila opravljena primerjava med termodinamičnim izkoristkom za enokomponentno hladivo R22 ter za njegovo zamenjavo z zeotropno zmesjo R407C. Predstavljena je konstrukcija hladilnega sistema, ki omogoča delovanje z R22 ter R407C skupaj z meritvami vseh ustreznih podatkov (temperatura, tlak in pretoki, njihovim zapisom ter analizo). Dobljeni rezultati kažejo, da je hladivo R407C dobra zamenjava za R22 pri višjih temperaturah uparjanja. Čeprav so teoretični rezultati vodili k predpostavki da bo R407C v primerjavi z R22 povečal izkoristek tega eksperimentalni rezultati niso potrdili. Razlog za to dejstvo je v nizjih toplotnih prestopnostih v primeru uporabe hladiva R407C</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-0R8EZX3A"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:doc-0R8EZX3A" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:doc-0R8EZX3A/a2b35a5f-b891-4f13-ac86-3ab03862e27e/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-0R8EZX3A/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:doc-0R8EZX3A" /></ore:Aggregation></rdf:RDF>
