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