Summary

The paper presents a prototype CO2 hermetic compressor, which is able to be used in carbon dioxide refrigerating systems. The compressor has two rolling pistons, and it leads to low vibration and low noise. In addition, two-stage compression with two cylinders is adopted, because pressure deference is too large to compress in one stage. The inner pressure of the shell case is intermediate pressure to minimize gas leakage between compressing chambers and the inner space of the shell case. As a result, the compressor achieved high efficiency and high reliability with this technology.
