Dynamic model for th orbiting scroll based on the pressures in scroll chambers / Qiang, Jianguo in International journal of refrigeration, Vol. 36 N° 7 (Novembre 2013) 

Public ISBD [article]  in International journal of refrigeration > Vol. 36 N° 7 (Novembre 2013) . - pp. 1850-1865 Titre : Dynamic model for th orbiting scroll based on the pressures in scroll chambers : Part II: Investigations on scroll compressors and model validation Titre original : Modèle dynamique de la volute rotative fondé sur les pressions dans les chambres de compression des systèmes à spirale-Partie II: étude éffectuée sur les compresseurs à spirale et validation du modèle Type de document : texte imprimé Auteurs : Qiang, Jianguo, Auteur ; Peng, Bin, Auteur ; Zhenquan, Liu, Auteur Année de publication : 2014 Article en page(s) : pp. 1850-1865 Note générale : Refrigeration Langues : Anglais (eng) Mots-clés : Scroll  compressor;  dynamics;  model;  investigation Résumé : This two-part study proposes a dynamic model for the orbiting scroll based on the pressures in scroll chambers. Part II investigates scroll compressors by using the dynamic model developped in this work to predicate the dynamic characteristics of the scroll compressors and the dynamic model is validated by comparing the predicted results with the experimental results of the powers of two air scroll compressors. This study utilizes two air scroll compressors and ten virtual scroll compressors to investigate the pressure distribution on the wrap surfaces of orbiting scrolls, the component forces and moments of orbiting scrolls, the overturning moment of the scroll mechanism, and the theoretical driving power of scroll compressors. The effects of scroll type (such as modified-wrap scroll, truncated-wrap scroll, multi-wrap scroll, odd-wrap scroll, and even-wrap scroll) on the dynamic performance of the scroll compressor based on the pressures in scroll chambers are also analyzed.
