[TRNSYS-users] questionable QINF

Wang,
I would recommend that you send your project to your TRNSYS
distributor for direct assistance. You have set your infiltration rates
in TRNBuild as constant values (independent of windspeed and direction)
for all three of your zones. However, your simulation couples the Type56
thermal model with TRNFlow. In most circumstances, TRNFlow would
calculate the infiltration rate and it may be that the constant values
that you are specifying (and then switching off) are actually being
ignored because of the TRNFlow integration. I am afraid I do not have
TRNFlow installed so I cannot check.
Regards,
David
