Abstract
Rashladni procesi odvijaju se posredstvom radnih tvari koje imaju povoljna termodinamička svojstva pri niskim temperaturama. U radu se opisuju svojstva sljedećih radnih tvari: amonijak, ugljikov dioksid, R-22 (klorodifluorometan), propan te R-134a (1,1,1,2-tetrafluoroetan) i ispituje utjecaj na karakteristične veličine u termodinamičkom procesu. Korišten je računalni program REFPROP pomoću kojeg su izračunata termodinamička svojstva čistih fluida kojeg je izradio NIST. Termodinamički proces prikazuje se u odgovarajućim termodinamičkim dijagramima kako bi se vidio utjecaj svojstava radnih tvari na energijske značajke. Budući da se sve više pridaje važnost zaštiti okoliša i utjecaja radnih tvari na okoliš, opisat će se primjena radnih tvari na isti.
Abstract (english)
Refrigeration processes use working media that have favorable thermodynamic properties at low temperatures. The paper describes the properties of the following working media: ammonia, carbon dioxide, R-22 (chlorodifluoromethane), propane and R-134a (1,1,1,2-tetrafluoroethane) and examines the influence on the characteristic thermodynamic variables in the thermodynamic process. The computer program REFPROP was used to calculate the thermodynamic properties of pure fluids created by NIST. The thermodynamic process is shown in the appropriate thermodynamic diagrams in order to see the influence of the properties of the working media on the energy characteristics. Since the importance of environmental protection and the impact of working media on the environment is becoming more and more important, the application of working media to it will be described.
