Abstract

In point of noise and vibration, it is easy to occur a noise and vibration, because the reciprocal compressor is composed of crank shaft, rod piston and etc. Therefore, it is important to understand the mechanism of reciprocal compressor. In this study, we measured the sound pressure level of compressor. There are two dominent frequencies. The first of one results from the suction part. In suction process, the suction valve flutteres, and it produces the noise of the first frequency. The other results from the structural vibration of the shell resonated by discharge pipe. Thus, to reduce the noise of compressor, it will be most efficiency to redesign muffler for the first frequency and discharge pipe for the second frequency.
