AHRI 530 (SI): Rating of Sound and Vibration for Positive Displacement Refrigerant Compressors

Standard Scope

​​​​This standard applies to hermetic, open type (external-drive), semi-hermetic, fixed displacement, discrete modulating, and continuous modulating compressors.  In the case of external-drive refrigerant compressors, the driving mechanism shall be excluded from the sound and vibration measurements.  However, for semi-hermetic refrigerant compressors where the driving mechanism is an integral part of the compressor assembly as defined in Section 3, it shall be included in the measurements.
