Résumé

This paper presents the analysis of the refrigerant mass flowrate of scroll type compressors. The study has included the data of several AHRI reports: (especially AHRI-11 and AHRI-21) as well as data from other sources. A total of 8 different scroll compressors of different sizes, tested with various refrigerants, have been considered in the study. The compressor mass flowrate, the corresponding volumetric efficiency, and the shape of the corresponding response surfaces, have been analyzed with the objective of understanding better the dependence of the compressor mass flowrate on the operating conditions and the refrigerant. One of the study results is that correlation of the mass flowrate as a function of pressures is more universal than as a function of temperatures. Two simple correlation polynomials, based on suction and discharge pressures, are presented, which require less empirical information and have better interpolation-extrapolation characteristics than the standard correlations.
