In the introduction, conventional refrigerants are compared with an alternative refrigerant - air. The system construction and the thermodynamic model are presented. The model is used to study the performance of a CFC-free air-conditioning system, in which some parameters of the individual components are variable while the others are constant for the referenced data. The characteristic performance curves of a simple air-conditioning system are defined as the coefficient of performance (COP), the temperature of the cooled outlet air, the compression presure and other parameters. Using actual data from an air-conditioning system we obtained performance curves of the system. Relations between specific parameters and quantities are presented in diagrams. Losses in the system, resulting from non-isentropic compression in the centrifugal compressor and expansion in the turbine expander and the irreversible losses of the heat transfer in the heat exchanger are explained"},{"@xml:lang":"sl","#text":"V prispevku sta opisana model in delovanje hladilnega postopka, ki za hladilno sredstvo uporablja zrak. V uvodu so opisana običajna hladiva, ki jih primerjamo z alternativnim hladivom - zrakom. Opisana je sestava sistema in termodinamični model. Model je namenjen za študij delovanja CFC-prostega zračnega klimatizacijskega sistema, pri katerem so ob referenčnih podatkih izbrani parametri spremenljivke, preostali pa konstante. Karakteristične krivulje so definirane s hladilnim številom COP, temperaturo ohlajenega zraka, kompresijskim tlakom in drugimi parametri. Karakteristike sistema so dobljene z dejanskimi obratovalnimi razmerami. Razmerja med specifičnimi parametri in veličinami so predstavljena z diagrami. Obrazložene so izgube sistema zaradi neizentropne kompresije v centrifugalnem kompresorju, ekspanzije v turbinskem ekspanderju in nepovračljivosti postopka prenosa toplote v prenosniku toplote"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:DOC-SC3SHBLK","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-SC3SHBLK"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-SC3SHBLK/61be92c3-0593-4247-92af-626a12b09044/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Univerza v Ljubljani, Fakulteta za strojništvo"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:DOC-SC3SHBLK/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-SC3SHBLK"}}}}
