Seminar 17 -- How to Select and Size HVAC Fans for Optimum Acoustical Performance

This product is a zip file that contains files that consist of PowerPoint slides synchronized with the audio-recording of the speaker, PDF files of the slides, and audio only (mp3 format) as noted.

This seminar provides basic information on how fans are measured for sound, why different fan types generate different sound levels, and why two fans with the same sound level but different fan design can sound totally different and yield very different sound levels in remote locations. Guidance is provided as to how to best select the appropriate fan type and size for a given application. Finally, case studies are presented illustrating real situations where a poor fan selection has resulted or could have resulted in a noise problem that was difficult and/or expensive to resolve.
