Static and Dynamic Analysis on R410A Scroll Compressor Components

This study investigated the static and dynamic phenomena on R410A scroll compressor components by using finite element analysis (FEA) with ITRI self-developed scroll type compressor software (ITRI_STC software). The simulation results of the coefficient of performance, cooling capacity by tuning the design parameters integrated scroll geometric parameters with compressed discharge procedure and dynamic equilibrium were presented by ITRI_STC software. The analyzed parts were fixed scroll, orbiting scroll, driving crank, and assemble part. The thermal and structural loadings were from ITRI_STC software. Those static and dynamic results were obtained by proper choices of boundary conditions. The temperature distribution, deformation, stress and modal shape were demonstrated in this paper. The final results were verified with the experiment pictures. The proposed procedures provide the failure problems of the compressor in advance. That information has provided designers to make some modifications for the weaker structural parts. Without making several real prototypes, it saves a lot of time and cost in the development of new compressor.
