A sensitivity study of size parameters in a twin-type rolling piston compressor / Jang-Sik Yang in International journal of refrigeration, Vol. 36 N° 3 (Mai 2013) 

Public ISBD [article]  in International journal of refrigeration > Vol. 36 N° 3 (Mai 2013) . - pp. 786–794 Titre : A sensitivity study of size parameters in a twin-type rolling piston compressor Titre original : Etude sur la sensibilité des paramètres des dimensions menée sur un compresseur à deux pistons roulants Type de document : texte imprimé Auteurs : Jang-Sik Yang, Auteur ; Lu Mei, Auteur ; Ki-Youl Noh, Auteur Année de publication : 2013 Article en page(s) : pp. 786–794 Note générale : Refrigeration Langues : Anglais (eng) Mots-clés : Rolling  piston  compressor;  Dynamic  analysis;  Sensitivity  study;  Energy  Efficiency  Ratio;  Optimization Résumé : In this paper, numerical studies on size parameters has been conducted to improve the performance of a twin-type rolling piston compressor, which has two cylinders called upper and lower cylinders with phase difference of 180°. In order to verify the computational reliability, the simulated results were compared with experimental ones. Sensitivity analysis of each parameter has been undertaken to investigate the influence of the parameters on compressor performance. Especially, size optimization has been studied to find an optimal combination of size parameters based on the sensitivity analysis of each parameter at the given operational condition and working volume. It was demonstrated that the maximum limits on the valve lift (ymax) and the suction port diameter (D_sp) showed the highest sensitivity to the compressor performance and optimum design condition, which corresponded to an Energy Efficiency Ratio (EER) that is 2.6% higher compared to the reference condition.
