[esp-r] imposed measured data - air flow network compatability

Hi all,

I have a single room model (essentially) that I'm trying to validate against measured data.  I have hourly temperature data for the corridor outside the room, which I have imposed as db temp of an arbitrary zone outside the door (all boundaries adiabatic as I do not care about the thermal performance of this space), and I have set up an air flow network such that the air from the corridor should infiltrate fairly slowly into the functional zone (via a door air flow connection, type 130).  However when I run a simulation and look at db temp results, the temperatures of the arbitrary corridor zone do not match the measured data imposed on the zone.  So my question is this: is the measured data imposition function compatible with an air flow network (ie. does the air flow node assigned to the corridor zone automatically pick up the imposed temperature data)?  If so then why does the db temp in the corridor zone not match the imposed data when I look at results?

I have ensured that all air flow nodes are correctly assigned and the measured data is assigned to the correct zone.  The corridor zone air flow node is set as a known internal (type 1) with a pressure of +3 Pa.  There are no other pressure sources in either zone (all windows fully closed, no hvac).

Thanks in anticipation,
Andy Cowie
