Description
This course provides a deep dive into the engineering criteria used to select fans that are stable, efficient, and durable. It challenges common industry "rules of thumb," such as fixed outlet velocity limits, in favor of a selection process driven by total efficiency and construction class. Participants will explore the mechanics of "System Effects" (the impact of ductwork and neighboring fans) and learn how to avoid common pitfalls when integrating accessories like filters and Variable Frequency Drives (VFDs).

Objectives
-
Explain why fans are volumetric machines and how to correct for air density variations due to temperature and altitude using fan laws.
-
Identify "unstable" operating zones on a fan curve and determine why operating at the Best Efficiency Point (BEP) is superior to following rigid outlet velocity guidelines.
-
Describe how "neighborhood conditions," such as elbows and fan-wall spacing, cause turbulence or recirculation that deviates from laboratory-tested performance.
Certificate
