Abstract: Focusing on the noise in refrigerator compressor, the mechanism of noise in refrigerator compressor is introduced, including mechanical noise, aerodynamic noise and electromagnetic noise, then the techniques and methods for noise reduction are summarized from the way to reduce noise source and isolate transfer path. Finally, the future development tendency on noise control technology is prospected, material of valve plate, lubrication of joint clearance, attenuation of gas pulsation, application of active noise control are worthy to be studied deeply.

Key words: Refrigerator compressor, Mechanical noise, Aerodynamic noise, Electromagnetic noise, Mechanism and control
