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 in case of using R410A than in case of using R22 or R407C. In this paper, the authors measured the motion of a check value (a reed valve) by using a gap sensor and also measured the noise of a compressor under various operating conditions. The relationship between the noise and each condition has been investigated. Consequently they have found that they can reduce the noise of a scroll compressor by the optimisation of the compression ratio.
