Linda,
Â
I don't find anything on the Tips and
Tricks document. I am not sure why this would be, I cant search for a
text "Multiplier", the results return no matching strings.
Â
Could you please give me the page number
in the PDF? Sorry for the trouble.

I think its the other way round. There is
some description on Zone Multipliers under the Zone object in the
Multiplier field. It seems like the inputs should be good enough to take
care of the mutiplied loads.
Try reporting the airflow and fan power to see if itâ??s the value
you specify or 7x that value. I have not used the zone multiplier,
but Iâ??m guessing that it multiplies CFM in the same magnitude as the
multiplier, so you now may have a fan at 7 x 7 = 49x.
I am seeing very high fan power on one of my simulations and hence
wanted to check for this issue.
Â
Let's say there are 7 typical floors and one zone is created and a
Zone Group object is used to replicate the 7 floors using a multiplier.
Now in all of those zones, the zone loads will be calculated and
multiplied by a factor of 7. So in order to satisfy this zone should we
input the designed zone CFM * 7 in the input field for HVAC objects or
input just the designed zone CFM and the software will mutliply it? It
would be great if someone can clarify this.
Â
I have it at 7 * designed zone cfm, and hence doubting my approach
due to high fan power. At the same time I feel this is the way to do it
from vague prior memory.
