Summary

Since a scroll compressor has a fixed compression ratio, the excessive motion of a check valve occurs under the over-compression and under-compression conditions. Moreover, the velocity of the motion is higher when using R410A than when using R22 or R407C. In this paper, the authors measured the motion of a check value (a reed valve) and measured the noise of a compressor under various operating conditions. They have found that they can reduce the noise of a scroll compressor by optimizing the compression ratio.
