In air conditioning systems the duct is considered a static component of the installation through which air flows within the building, connecting all parts of the system. Ducts can be best described as arteries of the central air-conditioning system. These play an important role in keeping the whole HVAC system fit and achieving comfortable conditions throughout its life span.
Defects in a duct system can waste hundreds or thousands of dollars a year by forcing the HVAC system to run longer than necessary. Ductwork problems also make certain rooms too hot or too cold at different times of the year, while introducing dirt and bad odors into the forced-air system.
The objective of good duct design is to:
This 6-hr course reviews the above criteria in detail and provides guidance on the planning, layout and sizing of supply and return air ducts.
Mechanical and HVAC engineers, project managers, architects, building designers, energy auditors, and facility managers will benefit from this course, as well as engineers of any discipline who are involved in the design, commissioning or operation of building systems.
Learning Objectives
Upon completion of this course, participants will be able to:
- Classify ductwork by velocity and pressure.
- Select duct materials and shapes that provide a cost-effective alternative for an application.
- Compare common supply-air duct configurations.
- Apply duct-sizing methods, including the velocity, equal-friction, and static-regain methods.
- Explain the interaction between a fan and the duct system.
- Describe methods of duct construction and reinforcement.
- Apply good engineering practices to duct layout and routing.
- Describe methods for testing ductwork and estimating system performance.
- Identify common duct-cleaning methods.
- Interpret typical duct-system performance characteristics.
- Explain the importance of system balancing and optimization.
Certificate of Completion
You will be able to immediately print a certificate of completion after passing a multiple-choice quiz consisting of 30 questions. PDH credits are not awarded until the course is completed and quiz is passed.
