ACCA & PAACCA Present Manual D in a Day








Manual D in a Day - March 9, 2022 in King of Prussia, PA

A key to comfort is about adding or removing the right amount of heat to keep customers happy. Easy rules-of-thumb lead to duct designs that cannot and will not deliver comfort. Many weak contractors fail to do a little leg work to set themselves up for success.

This course covers the fundamentals of residential duct design based on the nationally recognized standard. The class will break it down in a way that's easy to understand and apply. This program is designed for the HVAC professional who will use both a pen and paper, or a computer-based program to calculate duct sizes for residential structures. This program gives the user all the information necessary to use either method effectively. This class will also briefly discuss what’s needed for good room air mixing, selecting grills and registers (Manual T).

Topics covered include:

  • Duct Sketch
  • Total Effective Length Calculation (TEL)
  • External Static Pressure
  • Component Losses (Pressure Drops)
  • Available Static Pressure
  • Friction Rate
  • Use of a Duct Slide
  • Sizing of Branch Runs
  • Sizing of Trunk Ducts
  • Supply Register / Return Grille Sizing
  • Supply Outlet & Return Placement
