| Abstract: | First the vibration of chiller with open screw compressor operating in a pharmaceutical factory was analyzed;the faults and noise sources of the unit were determined based on the frequency spectrum and noise distribution and the project for eliminating faults and reducing noise was established according to vibration-acoustics analysis.And then a sound insulation cover was built by optimizing some parameters of the compound sound-absorbing structure.This method can provide the reference for faults diagnosis and noise control of the large-scale units. |

| Keywords: | chiller vibration-acoustics analysis noise control and sound-absorption structure |
