Software–Manual D Ductsize
Elite's Graphical Residential Duct-Sizing & Layout Add-On for Drawing Board
Requires RHVAC and Drawing Board
Manual D Ductsize works as a component within Drawing Board and RHVAC to calculate optimum duct sizes according to ACCA's Manual D. It will automatically create runout ducts in each room of your floor plan and assign them proper airflows as calculated by Rhvac. Manual D Ductsize will also generate reports that show the static pressure loss of each individual duct as well as the cumulative loss at each point in the system.
