Performance investigation with oil injection in the compression chambers of a CO2 scroll compressor.

Author(s) : HIWATA A., IIDA N., FUTAGAMI Y., et al.

Summary

For CO2 compressors with a small displacement volume, the leakage loss in the compression process increases due to the high pressure difference. The authors investigated the relationship between the performance and the oil-injection rate in the compression chambers, and found that an optimum oil-injection rate exists. The paper presents the experimental relationship between the performance and the oil-injection rate. By optimizing the oil-injection rate, their prototype CO2 scroll compressor achieved a higher efficiency of 102-109% compared with the 2-stage rotary compressor that they developed.
