Summary

This article is the Spanish translation of an article presented at the IIR meeting in Castá Papiernicka, Czech Republic (see Bulletin of the IIR, reference 2007-0610). In the design of compressors to run with high pressure refrigerants like CO2 safety aspects must be a mandatory concern. Moreover, when dealing with high pressure levels, compressor components have their original design adapted to withstand such a high pressures, particularly acoustical mufflers, external shell, and compression mechanism. Regarding the external shell, the design approach goes beyond acoustical and aesthetics features as mostly observed in current refrigerating compressors. In order to safely enclose the compression mechanism, the application of a proper design methodology is mandatory to safeguard the structural integrity of both the compressor external shell and the whole refrigerating system. Looking for acceptable, cost-effective safety factors, a simultaneous design approach including advanced structural mechanics techniques, experimentation, safety standards revision, and computer aided engineering tools application is mandatory. The aim of this work is to present how Embraco has been approaching the structural design of its CO2 compressor.
