Abstract: The demand for HVAC chiller systems in commercial centers is ever-increasing. Chillers with centrifugal compressor units produce high-frequency noise, a significant problem that needs to be addressed. The blade passing frequency is the primary noise source a centrifugal compressor generates. The objective of this paper is to investigate the vibro-acoustic performance of an oilfree two-stage centrifugal compressor with magnetic bearings via numerical modeling.
