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

Hi Mike,

I have another three questions on this issue:

1.I want to estimate the zone extraction air temperature without
adding any HVAC equipament. When estimating the heating load, I used
the "INFILTRATION" object and not the "OUTSIDE AIR FLOW" field in the
"PURCHASED AIR" object, to bring the total outside air to the zones,
in order to avoid the "PURCHASED AIR" outside air shutt off in the day
periods when there is no heating load. Is this assumption correct?

2.In order to avoid using HVAC equipment, is it possible to use the
"INFILTRATION" object in the adjacent zones and indicate the outside
air as infiltration, in order assure that the extraction zone is
extracting the correct amount of air and assure the airflow balance?

3.In the I/O Reference documentation, it´s not very clear where
temperature rise due to the exhaust fan power, is accounted. Is this
defined in the "DELTA TEMPERATURE" field on the "MIXING" object? Or do
I have to define a "Zone Exhaust Fan" object per extraction zone? I´m
not sure if i understood this field, is it the temperature diference
between the two zones? But that´s exactly what I want to estimate!!?

Thank you for your patience.
Regards
Nuno Brandao
