[Equest-users] G3.1.3.12 Supply Air Temperature Reset

[Omar Katanani]

Dear Jenny,

Do you have an idea of what shall we put for the Proposed Case?

I have a regular VAV system serving multiple zones. I tried 2 simulations: 1 with the Cool Control being "Constant" and 1 with the Cool Control being "Warmest" (similar to the baseline). I got an improvement of 17.5% in the first case, and 20.2% in the second case. I thought this parameter was not that significant, but it turned out to be so!

Which option do you suggest to adopt for the Proposed Scenario?

Many thanks!
Omar

Hi Omer,
you can find reset option in the airside system screen(COOLING).
my approach is to choose reset>warmest>airflow first.(For VAV system I think the airflow will reduce first to satisfy load then the supply air temperature could rise at the minimum air flow rate.) 
the dealt t for reset is according to ASHRAE 90.1.

Regards
Jenny Z

Dear All,

In eQuest, how can the air temperature for cooling in a VAV system be 
reset as required by G3.1.3.12?

Thank you,
