DM HVAC Feature
CFM and Sizing Calculations
Design Master HVAC calculates the right airflow volumes and duct sizes for your system.
As you draft you can set the CFM required for each diffuser, whether each duct is sized to maintain velocity, pressure drop, or static pressure, as well as how and whether the shape of the duct changes during sizing.
When you’re ready to calculate, simply run the command and the ducts will be sized according to the values you set. Need to change a single duct or diffuser? Make the revision and recalculate — the software handles how the change affects other ductwork in the system.
CFM Per Diffuser
Set the airflow required for each diffuser while you draft — no separate spreadsheet needed.
Flexible Sizing Methods
Choose velocity, pressure drop, or static pressure sizing per duct, and control how duct shape changes during sizing.
One-Command Recalculation
When you make a revision, just recalculate — the software propagates the change through the rest of the system automatically.
