Recently, for each contury’s energy efficiency policy is strengthened, air conditioner demands higher energy efficiency too. Following it, high speed inverter compressor research is carried out but high speed inverter compressor occurs compressor noise and vibration increase due to its refrigerant flow speed and rate. This noise and vibration is delivered around parts, finally it leads noise increase of entire product. Generally accumulator and muffler is used for reduce noise but it can not block abnormal noise and pulsation noise at high speed rotary compressor. This study suggests solution of noise improve by change accumulator internal pipe fixing method and block pulsation noise by change its shape.
