[TRNSYS-users] WEIRD phenomena

Dear all,
I control OP(window opening factor) in order to make indoor CO2% lower than
0.001476 kg/kg (900 ppm) based on indoor CO2%. I used 2 simple methods:
1) OP=(LT(0.001476, CO2%))*1, i.e. if CO2%>0.001476, OP=1 windows will open
completely;
2) I defined SCHEDULE 001: about every 1 or 2 hours, OP=1 during 15 mins, 6
cycles.
BUT the two methods' results are very weird. to 1): OP is from 0 to 1 then
to 0, there are 6 cycles during 24 h, 1 open/close cycle about only 6 mins,
but FLTOZ: escaping air flow mass about 3000kg in all, CO2% is indeed lower
than 900 ppm; Please see the ATTACHED 1st and 2nd, 3rd is the
Online-plotter. FLTOZ can be seen from the *.out file 4th Attached.
to 2): SCHEDULE 001 is from 0 to 1, after 15 mins, from 1 to 0, there are
also 6 cycles during 24 h, 1 open/close cycle about 15 mins, ALTHOUGH cycle
time is bigger than 1): 6 mins, FLTOZ: escaping air flow mass about only
1550kg in all (weird), CO2% is higher than 900 ppm sometimes (weird); Please
see the ATTACHED 5th and 6th, 7th is the Online-plotter. FLTOZ can be seen
from the *.out file 8th Attached. SCHEDULE 001 can be found in TRNBUILD
file.
I can't understand why 2)'s opening time is bigger than 1) and its open type
is complete open during 15 mins (like a rectangle), but FLTOZ (escaping air
flow mass about only 1550kg in all), CO2% is higher than 900 ppm sometimes ,
however, 1)'s open type is from 0 to 1 then to 0 only during 6 mins like a
triangle, but FLTOZ (escaping air flow mass about 3000kg in all), CO2% is
indeed lower than 900 ppm?
Please give me some advices! I think the problem may be TRNSYS and TRNFlow
compatible reason.
Many thanks in advance!
