R410A Scroll Compressor Design Verification used with Finite Element Analysis

摘要

One ITRI developed R410A scroll type compressor was analyzed in this study by using finite element analysisrn(FEA). Through ITRI developed scroll type compressor computer software (ITRI_STC), the needed boundaryrnconditions, such as pressure in chambers and temperature distributions during one complete orbiting cycle of thernscroll pairs, can be obtained as input data to FEA. This study firstly focused on the orbiting scroll, and the FEArnprocedure was performed by two commercialized computer packages (SolidWorks and ANSYS). The temperaturerndistribution, deformation and stress profiles for the orbiting scroll were showed and discussed under differentrnoperating conditions. The analyzed results can assist designers not only to improve their design for weaker structuralrnparts, but also reduce the time and cost in developing the new scroll type compressors.
