Studies on the performance of a small reciprocating compressor with different nitrogen–hydrocarbon mixtures / N. Lakshmi Narasimhan in International journal of refrigeration, Vol. 36 N° 8 (Décembre 2013) 

Public ISBD [article]  in International journal of refrigeration > Vol. 36 N° 8 (Décembre 2013) . - pp. 2091–2096 Titre : Studies on the performance of a small reciprocating compressor with different nitrogen–hydrocarbon mixtures Titre original : Etudes sur la performance d'un petit compresseur à piston avec différents mélanges d'azote et d'hydrocarbures Type de document : texte imprimé Auteurs : N. Lakshmi Narasimhan, Auteur ; G. Venkatarathnam, Auteur Année de publication : 2014 Article en page(s) : pp. 2091–2096 Note générale : Refrigeration Langues : Anglais (eng) Mots-clés : Joule–Thomson  refrigerator;  refrigerant  mixtures;  compressor;  adiabatic  efficiency Résumé : The performance of Joule–Thomson refrigerators operating with mixed refrigerants depends on the composition of mixtures as well as the hardware employed. The role of mixture composition on the overall performance of the system has been well addressed in the open literature. What is not well known is the role of mixture composition on the performance of individual components such as the compressor, heat exchanger, etc. The adiabatic efficiency of a single stage Joule–Thomson refrigerator compressor was measured with thirty different nitrogen–hydrocarbon and neon–nitrogen–hydrocarbon mixtures. Our results show that the adiabatic efficiency of the compressor is independent of the mixture composition in the range of pressure ratios tested.
