I'm trying to use the "Duct Static Pressure Reset Curve Name" field of the Fan:ComponentModel object to have the VAV dampers open more at lower flow rates allowing the fan to run at a lower pressure and power, thereby saving energy. However, I can't seem to get the "Duct Static Pressure Reset Curve" to influence the simulation, even when changing the curve value by a factor of 10 in either direction.
I suspect I'm not interpreting the curve correctly, or do not have an appropriate paired object. Is there an example file for a non-constant "Duct Static Pressure Reset Curve" available? The ExampleFiles-ObjectsLink.html only lists files with a constant "Duct Static Pressure Reset Curve" called DiagnosticSPR
Curve:Linear,
DiagnosticSPR, !- Name
248.84, !- Coefficient1 Constant
0., !- Coefficient2 x
0., !- Minimum Value of x
100., !- Maximum Value of x
62.5, !- Minimum Curve Output
248.84; !- Maximum Curve Output
Is there another way to get my VAV dampers to open more and lower the fan pressure and power? There's a lot of room for improvement in my file as the VAV are usually 30% open at the lowest flow rate with the pressure mostly constant at 534 across the fan.
