Noise reduction of a rotary compressor using structural modification of the accumulator.

Author(s) : KIM J. D., LEE B. C., BAE J. Y., BAN J. O., KIM Y. H.

Summary

Several experimental trials and analytical approaches are used to show that the high-level abnormal noise has the unique frequency characteristic and arises from the suction accumulator. The results are useful clues to reduce abnormal noise in the troublesome frequency band. Consequently, some structural modifications of the accumulator result in the reduction of abnormal noise level by approximately 20 decibels.
