IDEA #2XLZIK Method and Device for Acoustic Length Testing of Compressor

Computer system (94) and method for determining frequencies of various components of a volume choke volume dampener (30, 50) to be attached to a compressor (20). The method includes determining a sound spectrum of a cavity (22, 24) of the compressor (20) without attaching the dampener (30, 50) to the compressor (20); calculating an acoustic wavelength of the cavity (22, 24); receiving a length of a proximal nozzle (52) of the dampener (30, 50); and calculating, based on the acoustic wavelength of the cavity (22, 24) and the length of the proximal nozzle (52) of the dampener (30, 50), multiple order frequencies associated with the proximal nozzle (52) of the dampener (30, 50) and the cavity (22, 24) of the compressor (20), wherein the proximal nozzle (52) of the dampener (30, 50) is proximal to the cavity (22, 24) of the compressor (20) when the dampener (30, 50) is attached to the compressor (20). https://app.acclaimip.com/pdf/IYxVhNeBXM7HjFXhMoFcwqwzbwYKJZ0vfMzbiyA/EP2199613A2
