this is the example from LBT1.3 download files, and the idf I got. I try to understand, the settings of Airflownetwork,
AirflowNetwork:MultiZone:Zone,
Loft_855163f2, !- Zone Name
NoVent, !- Ventilation Control Mode
, !- Ventilation Control Zone Temperature Setpoint Schedule Name
0, !- Minimum Venting Open Factor {dimensionless}
0, !- Indoor and Outdoor Temperature Difference Lower Limit For Maximum Venting Open Factor {deltaC}
100, !- Indoor and Outdoor Temperature Difference Upper Limit for Minimum Venting Open Factor {deltaC}
0, !- Indoor and Outdoor Enthalpy Difference Lower Limit For Maximum Venting Open Factor {deltaJ/kg}
300000, !- Indoor and Outdoor Enthalpy Difference Upper Limit for Minimum Venting Open Factor {deltaJ/kg}
, !- Venting Availability Schedule Name
Standard, !- Single Sided Wind Pressure Coefficient Algorithm
10; !- Facade Width {m}
-
can we change the Ventilation Control Mode to other types like “Temperature” or “Enthalpy”? I didn’t find a component to do this
-
the Ventcontrol component will effect the following code, and change the open factor of the openings. But like the E+ reference says: " NoVent : All of the zone’s openable windows and doors are closed at all times independent of indoor or outdoor conditions. The Venting Availability Schedule is ignored in this case. This is the default value for this field." So what is the meaning of the Ventcontrol then?
