[TRNSYS-users] Strange Opening Factor (OF) of Window

[王洋]

Dear all,

     I simulated CO2 concentration changes using TRNFlow. But there is a
STRANGE phenomenon. There are 2 occupants from 8am to 6 pm, CO2% is
controlled by PID controller which controls Opening Factor (OF) of window at
the set-point 1000 ppm. From 6 pm, there are no occupants, OF is 0, there is
no infiltration in TRNBuild (Certainly, infiltration in TRNBuild indeed will
inactivate when couping TRNFlow based on TRNFlow Manual). However, from 6
pm, CO2% begins to decrease. It's extremely strange!

   Which relative expert can expain that? Or give me some advices for that?
I am puzzled for a long time.

   Many thanks in advance!
