Manual-D Training (Now Offered Online, Too!)
Manual D is the name for the protocol used to properly size the air distribution system of a forced-air HVAC system. This protocol, like the Manual J, was developed by members of the ACCA (Air-Conditioning Contractors of America) contractors association, and engineers at ASHRAE (American Society of Heating, Refrigeration, and Air-Conditioning Engineers).
Completing a Manual-D is the best way to ensure that a heating and air system will deliver maximum comfort at peak efficiency. The only way to ensure your system will be able to deliver the correct amount of air to each room of the house is to perform a Manual-D. We’ll also cover Manual-T (Terminations) in the class as well. This manual deals with the selection of registers and grilles to ensure proper mixing of air.
Fortunately, the use of computer software makes this relatively easy. However, the process must still be followed accurately if you want accurate results. We generally offer this class immediately following our Manual-J/S classes. After reviewing the overall process and a variety of tables in the book, we demonstrate the use of Wrightsoft software to complete the layout and sizing of duct systems.
You’ll complete the design of a few duct systems using this software during the class. And, you’ll have the opportunity to work through a few examples during class to explore scenarios that include:
- Defining your ductwork materials and components
- Specifying available static pressure
- Reading equipment blower charts
- Manual-T basics (Where’s the best place to put those terminations?)
- Zoning (including bi-level zoning)
- Specifying risers
