Fans used in air-handling systems often have a significant impact on energy use and acoustics. How much of an impact depends on how a fan is selected, installed, and operated.

Join Dennis Stanke, John Murphy and Dave Guckelberger as they discuss fan performance curves and fan laws, different fan types (fan blade shape, housed vs. plenum fans, direct-drive plenum fans, fan arrays), how a fan interacts with various types of systems, considerations when selecting a fan (efficiency, acoustics, footprint), and the ASHRAE Standard 90.1 fan power limitations. What you will learn:

  • How to select, install, and operate fans to avoid problems related to inadequate airflow or excessive noise
  • When to select the different fan types (housed vs. plenum, belt-drive vs. direct-drive, single fan vs. a fan array)
  • How to design fan systems to meet the prescriptive requirements of ASHRAE Standard 90.1-2007
  • This ENL has a supplemental Engineers Newsletter article.
