Syllabus for course Residential duct sizing
Course if for both Master and Journeyman
Instructor: Bruce R Waters E-Mail brwaters@adelphia.net
Course objectives
Participants should understand, How air moves, what cause air movement problems, and what
indication of air movement problems, and how to solve air movement problems
Participants should understand terms of duct systems, how to find the longest duct run what the
equivalent length of a fitting means, how to do a duct system layout that will work.
Participants will see some of the pitfalls that can be encountered and how to avoid them
Course topics:
How air move, the driving force, static pressure, atmospheric pressure,
Incline manometer, Magnehelic gages, Losses cause from installed item in system Static pressure and friction,
Velocity pressure, Cause of inaccuracies in velocity, Calculating Air flow volume
Using heat rise method and Pressure drop across components for Air volume
Basic design limits of duct system, identify and fixing air flow problems
Blower operating curves
Duct sizing for proper losses, to reduce noise
The principles of duct sizing, Some sure signs of problems
Terms used in duct sizing, Types of duct system Parts of duct system and distribution system What transition and bends do to air movement? Equivalent length of duct for fittings
Doing a duct design on an example system
Class is 8 hour credit class
The course is design to increase the awareness of attendees of the importance of the correct duct instillation to system performance and to customer comfort. The course is intended to help the HVAC Contractor and Journeyman to reduce customer complaints and call back. The course applies to code requirements of heat loads calculation and duct sizing to meet the load requirements for the individual room. Manual D is an ACCA publication recognized as an industry standard
