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.
This program discusses 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
