Magnetic Bearing Technology is becoming increasingly common place in the built environment. This presentation will address acoustic testing and rating standards for magnetic bearing chillers and compressors. This includes understanding the sources of sound generation and learning how to isolate magnetic bearing compressor acoustics from the overall sound generation of the chiller. From there, participants will learn how to acoustically plan for magnetic bearing chillers during design and how to “put a stethoscope on your equipment room” to overcome problems in the field if the quiet chiller isn’t quiet enough.
