The scroll compressor having an asymmetric scroll wrap has been developed as a kind of means to attain the high efficiency, low noise, and compact size as compared to that with a symmetric scroll wrap in recent years. However, an asymmetric scroll compressor causes the large imbalance gas forces due to the pressure difference in a pair of compression chambers. The forces influence dynamic behavior of the orbiting scroll and the Oldham ring, and they will lead to the unfavorable noise and vibration during the operation. In this paper, we have identified such problems of an asymmetric scroll by measuring the motion of Oldham ring and the acceleration of the casing under the various operating conditions. We have compared the experimental results with those of a symmetric scroll. In addition, we have suggested the effectiveness of a reed valve as a discharge valve to reduce the impulse noise and the rotational displacement of Oldham ring, and have tried to optimize the shape of reed valve with the help of the experimental planning method using the orthogonal array.
