[EnergyPlus_Support] Re: Help!! - Estimating Extraction Zone Air Temperature

["brandao_nuno" <ncostab@xxxxxxxxx>]

Dear Mike,

I have one more question. I chose to model the EXHAUST FAN, but after
simulating, i obtained the following warning:

** Warning ** The following lines are "Orphan Objects".  These objects
are in the idf
   **   ~~~   **  file but are never obtained by the simulation and
therefore are NOT used.
   **   ~~~   **  See InputOutputReference document for more details.
   ************* Object=ZONE EXHAUST FAN=VE WC CRIANÇAS

I couldn´t obtain the "System Node Temp".
I believe that in order to model the ZONE EXHAUST FAN, i have to
specify some equipment which "tells" to the exhaust fan in the
extraction zones, that air is entering the zone, even if this outside
air, is specified in the INFILTRATION object(or do i have to specify
it as outside air in the PURCHASED AIR object?). Does That means i
have to introduce a PURCHASED AIR object (avoing any HVAC equipment)
even if the zone is not controlled? 

Thank for your help
Regards
Nuno Brandão
