Study on the Reduction of Vibration and Noise of the Compressor in a Refrigerator

In this paper, the theoretical and experimental analysis on the problem of vibration and noise of a compressor is carried out. Based on it, a new method to reduce noise and vibration of the compressor assembled in a refrigerator is developed. According to the theory of high frequency vibration insulation, the vibration insulation system of the compressor is redesigned. A lot of experiments are carried out. It is proved that the sound power level of the improved compressor reduced from 37.3 dB(A) to 35 dB(A), moreover, the amplitude of the vibration reduced from 3.2 m/s 2 to 1.6 m/s 2. A good result of reduction for vibration and noise is acquired. It shows that the improvement of the vibration insulation system of a compressor is a useful method to reduce the vibration and noise of the compressor.
