to this, has anyone been successful in controlling the max CFM out of a unit
with seasonal schedules. For example, a system can produce 15000 CFM during the
winter but 30000 CFM during the summer? This would help me with the modeling of
these supplemental supply fans that serve the warehouse space as they only
operate during the summer. My strategy would be to schedule this extra CFM
during the summer, though I am still trying to figure out how to properly model
the actual energy usage since the fan power from the make up units differ from
the supply fans…<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I am working on an energy model for a warehouse in <st1:place
w:st="on"><st1:City w:st="on">Dallas</st1:City>, <st1:State w:st="on">TX</st1:State></st1:place>.
The design intent of the warehouse area required 1 air change per hour during
the summer. The fans are suppose to operate simultaneously as makeup units that
serve the warehouse. Therefore, 10 make up air units and 10 supply fans serve
the warehouse area to meet this air change requirement. Modeling the makeup air
units can be done by eQuest but I am curious how I should incorporate the
supplement supply fans?<o:p></o:p></span></font></p>
