In general, compressors for refrigerators are major noise source in home environment. The vibration originated from a pump of a compressor can make noise through suspension springs and a LDT(Line Discharge Tube). Especially for the inverter motor driven compressor, the vibration is more serious than it of the constant speed compressors. Because the operation frequency range of an inverter motor driven compressor is very wide from 1600 rpm to 4200 rpm. In this paper, we propose the numerical model to reduce vibration by designing weight balancers and grommets. Results for analytical investigations on the exciting force and moment at the pump mass center, weight balancers and exciting frequency variation are presented.
