An experimental study on the thermal stress and deformation of the scroll compressor

스크롤 압축기의 열응력 및 열변형에 관한 실험적 연구

In this study, an experimental method measuring the scroll under the temperature distribution similar to the operating condition is proposed and the results are presented. Direct measurement of the actual thermal stress is very difficult because of the rapid and complex motion of the orbiting scroll. Therefore, the experimental condition is provided on the stationary scroll heated in the electric furnace and, then, the mechanical stress and the effects of refrigerant are excluded from the resulting measurement. The experimental results are compared with these of FEM, both showing good agreement.
