[Equest-users] eQUEST: Hours outside throttling range for Standard VAV w/Reheat

[John Aulbach]

Gordon:

Try increasing the throttling range to 6 DegF. Also find out WHEN your unmet hours exist by looking at SS-O reports, which show 8760 of space temperatures based on time of day.  If I get a chance later today, I will look at your run.

Subject: [Equest-users] eQUEST: Hours outside throttling range for Standard VAV w/Reheat


All,
 
I am modeling a "Standard VAV w/Reheat" for a small college building (~20,000 SF) and am having some difficulty reducing my hours outside of throttling range. I have tried increasing my "Throttling Range" to 4 F, increasing my system size capacity (from 1.15 to 2), and have also adjusted my "Heat Temp Schedule" to turn all but one zone to default to create a 'control zone' for the system.  However, I still have many unmet hours (~39% of hours outside of throttling range - my BEPU report does not identify hours, but rather a % (reference previous Equest thread)).
 
Any suggestions are certainly welcome!
 
Thanks in advance,
 
Gordon
