[BLDG-SIM] Static pressure reset control

[Graham & Megan]

Gary,
The only mechanism you have in EQuest/DOE-2.2 is to change the FAN-EIR-FPLR,
the way power input varies with flow output.  The most appropriate curve for
you application will depend on the distribution network, location of duct
static pressure sensors, pressure setpoint and fan selection.  In simple
terms constant duct static pressure will vary flow approximately to the 1.8
to 2.2 power of flow while pressure reset will approach a cube law as
throttling losses are minimised.  The guys at Taylor Engineering put
together quite a good report on VAV systems earlier this year which is
available off the California Energy Commission's website.
Regards,
Graham

> I am now working on simulation of a 20 floors VAV system,in which the
owner required that the comparation of two kinds of fan control method
should be provided. Can equest run simulation about VAV with fan static
pressure reset control?
