Development of Scroll Compressors for R410A

摘要

We have completed development of the new scroll compressors for R410A by upgrading our existing air-conditioners' scroll compressors. We have incorporated our various technologies into developing these R410A new scroll compressors and have succeeded in several major achievements, including: 1) Optimization of the orbiting scroll back pressure force, which reduces the thrust bearing loss; 2) Optimization of the scroll wrap dimension, which achieves high COP; 3) Improvement of shell strength, which endures 15.2MPa high side pressure.
