[Equest-users] Changing Ventilation Rate for some months in the year

[fraij]

Hello Ethan,Thanks for your replyI am trying to change the OA CFM. I created schedules as you suggest below but I could not find the OA CFM fora each zone after I apply these schedules and the OA CFM in the report SV-A did not change.Do you know where can I find the OA CFM after I apply the new miniminum outside air schedule?Thanks for the help againRegardsAhmad

Ahmad,

Are you trying to vary the system CFM or OA CFM?  See below for eQuest’s definition of Minimum OA Sch.  The minimum OA schedule varies the hourly OA ratio.  To create an annual schedule to vary the CFM seasonally you can create an additional set of weekly/daily
 schedules, and then set the run times in the annual schedule.

Hello Guys,


 


Did  anyone have a chance to review my question in my email below?


 


I found the option to add "Minimum OA Schedule" but this schedule is fraction of what? Is it fraction of the CFM/person values that we enter in the Zones? I have added this
 schedule and changed the fractions and the energy consumption and the heating loads have been changed but the OA air flow rate & ratio in the report SV-A has not changed? Am I missing something? 


 


If the "Minimum OA Schedule" changes the OA flow rate, then where can I find this value? I am trying to change the OA flow rate for a specific value for only three months
 per year for pandemic mitigation so how can I do that?


 


Any help will be highly appreciated


 


Regards


 


Ahmad

Hello Guys,


 


How can I change the ventilation rate for a building in eQUEST software for only three months of the year (Dec, Jam & Feb)?


 


Your help will be highly appreciated.
