  • HVAC: A Guide to the Optimization of Airflow in Air Distribution Ductwork

    Credits: 3 PDH

    PDH Course Description:

    This course offers a comprehensive examination of airflow dynamics and duct design strategies critical to the performance of Heating, Ventilation, and Air Conditioning (HVAC) systems. Engineers will gain practical knowledge and design insight into the optimization of air distribution ductwork for energy efficiency, indoor air quality, occupant comfort, and system longevity. 

    This guide bridges the gap between theoretical principles and real-world application, with emphasis on duct sizing, layout strategies, pressure loss mitigation, velocity management, and troubleshooting performance deficiencies in both residential and commercial systems.

    Topics:

    Upon completion of this course, participants will be able to:

    • Understand the fundamentals of airflow behavior in ducted HVAC systems.
    • Analyze pressure loss due to friction, fittings, and layout design.
    • Apply duct sizing principles using velocity and friction loss methods.
    • Evaluate the impact of duct material, geometry, and insulation on system performance.
    • Optimize duct layouts to minimize energy consumption and balance airflow across zones.
    • Diagnose and correct common issues such as noise, turbulence, and airflow imbalance.
    • Incorporate advanced tools such as computational fluid dynamics (CFD) and airflow measurement instruments into design and commissioning.
    • Integrate optimization practices with relevant codes and standards, including ASHRAE and SMACNA guidelines.
