VAV Box Noise Issue
VAV Box Noise Issue
(OP)
We just added an VAV box in an office to provide addtional cooling air and individual temperature control for the office. However, there's substantial increase of the noise level, about 65 db, especially when the VAV box is fully open. Can anyone advise what's the possible causes and how can we fix it?
Thanks.
Thanks.

Usually, inlet diameter determines VAV-box size. If one VAV box cannot meet noise criteria, consider using two. Two or more VAV boxes can be controlled with one temperature sensor. For more go here:http://hpac.com/mag/vavbox_selection_code/
