[Equest-users] Sizing of equipment

[Brahme, Rohini UTRC]

Check for reverse acting thermostat, or make sure that your min-air flow
for heating is sufficient.

Hey All,

 

I am running a load with many zones on 5 floors totaling over 300 zones.
There are some zones with many unmet hours, some of the core, some
perimeter. I went in and changed the sizing ratio of these zone to
reduce the unmet heating hours. I am modeling this building with 9
AHU's, all VAV w/ reheat. Does anyone have any insight or suggestions on
why or how these unmet hrs. exist. I have changed the hot water loop
flow GPM but it had no effect on the unmet heating hrs. so I deduced
this is not the cause.
