Airflow Class in a Half Day








Airflow Class in a Half Day - 

ACCA’s airflow course lays the foundation for airflow measurement in the field. Before learning how to measure airflow, you must know the target, the design airflow that you’re aiming for. In addition, you’ll learn about various ways to estimate or measure airflow along with a demonstration how to perform the tests. You’ll also about the importance of air velocity and the difference between residential vs commercial applications. If you want to learn the basics to accurately quantify airflow and understand the limitations of various procedures, then this is the class for you.

Topics covered include:
  • Introduction
  • What is correct airflow?
  • Why do we measure airflow?
  • Mass flow vs CFM
Methods of measuring airflow
  • Static pressure
  • Pitot tube / formal traverse / Tchebycheff method
  • Hotwire
  • Mini vane
  • Temperature rise
  • External Static Pressure
  • TrueFlow® grid x 2
  • Pressure matching
Other useful measurements
  • Coil pressure drop
  • Filter pressure drop
Bonus material (as time allows) – system BTUH calculations: heating plant output, AC total BTUH output, and the importance of enthalpy (Δh).
