GB/T 27698.7-2011 Test method for the performance of heat exchangers and heat exchange element—Part 7:Measurement of noise from air-cooled heat exchangers
Abstract
This part of GB/T 27698 specifies the measurement methods for the A-weighted sound level, octave sound pressure level, and sound power level of air coolers.
This part is applicable to air-induced air coolers and blower-type air coolers with horizontally arranged tube bundles. The noise measurement methods for inclined-top type, wet type, dry-wet combined type, and other types of air coolers can be referenced from this part. This part is not applicable to individual components that generate noise (such as impellers, drive mechanisms, and electric motors, etc.).
