Hi
I am trying to regulate outdoor air flow in an Air Loop in E+
DesignSpecification:OutdoorAir,
FirstFloor:Office Design Specification Outdoor Air Object, !- Name
Flow/Zone, !- Outdoor Air Method
0.000, !- Outdoor Air Flow per Person {m3/s-person}
0.000000, !- Outdoor Air Flow per Zone Floor Area {m3/s-m2}
1.500000, !- Outdoor Air Flow per Zone {m3/s}
0.000000, !- Outdoor Air Flow Air Changes per Hour {1/hr}
MyTemp_SCH;
Essentially I am using EMS to vary the value of MyTemp_SCH to values between 0 and 1 dependent upon zone air temperature.
The program to modulate the value is called at BeginTimeStepBeforePredictor and I have monitored these values and they do vary as anticipated
However, the flow into the zone remains at 1.5m3/s even though I would expect this value to be adjusted because of the use of MyTemp_SCH in DesignSpecification:OutdoorAir
any ideas?
many thanks
