Supply Air Volume in Supply Air Requirements

Posted on April 21st, 2010. Last updated on September 20th, 2018.

Two numbers for supply air volume are included in the Supply Air Requirements section of the HVAC load calculation report.

Required Supply CFM is calculated based upon the load in the room. It should always be a nonzero number.

Current Supply CFM is based upon the diffusers inserted in the room. If this is 0, it is most likely because there are no diffusers in the room.

Ventilation or Psychrometric Airflow Values are 0

If your building load calculations don’t show any outside air, ventilation load, or airflow, you must modify your project information or insert supply diffusers with airflow on your drawing.


Duct-Mounted Diffusers

Design Master HVAC does not have a command specifically for inserting or connecting duct-mounted diffusers and grilles. However, you can approximate them by inserting the diffuser close to the duct to which it is mounted.


“Locked Layer” Error Message

Design Master typically unlocks any locked layers it needs to use to function. If it can’t, it will display an error message telling you to unlock the layers.


DM Entities Insert Skewed or in the Wrong Location

If your Design Master entities come in skewed or in a different location than the one you specified, try resetting your drawing view to “Top” and reinserting.


Manual J Calculations

Design Master does not specifically include Manual J as a calculation basis, but will provide results that are at least as precise.


Exporting Load Calculations (and Other HTML Outputs) to Excel

Some HVAC and Electrical reports can be exported as HTML files. Here are three easy ways to open those files in Excel.
