Checking Supplied CFM
|Top Previous Next|
To quickly visualize whether the correct amount of CFM is supplied to each room, use the Room Attributes Load Calculation Map. To insert this map, go to
DM HVAC Load Calculations Display Load Calculation Map
Select Room Attributes in the left-hand side of the Load Calculation Map dialog and Percentage of Required CFM Supplied in the right-hand side. When prompted, place the scale on the drawing. Your drawing should match the one shown below.
Note that rooms with 100% of the required supply air are colored in white and that rooms needing more supply air are colored in shades of blue. This lets us quickly see that the rooms in the building need more supply air. Next, we will use the Set CFM commands to set the diffusers to supply more air
