[TRNSYS-users] infiltration rate

Dear all,
I want to compare the test room infiltration rate of actual measurement with
by TRNSYS simulation. Maybe as you know, in the TRNFlow manual: there it is
explained that "As soon as TRNFLOW is turned on, (...) in the simulation the
defined infiltrations, ventilations and couplings will be replaced with the
calculated air flows."
I defined CO2% as 1000 ppm in TRNFlow, then I want to observe CO2%'s
reducing curve when infiltration rate is 0.5276 1/h (I measured the value in
the test room), so I defined the infiltration rate as 0.5276 1/h in
TRNBUILD. But when I used TRNFLOW, the defined infiltration rate as 0.5276
1/h in TRNBUILD was replaced. And 1000 ppm keeps constant.
Please tell me how to get the infiltration rate curve using TRNSYS/TRNFLOW
or how to explain this ?
Many thanks!

>>> Dear TRNSYS users,
