modelMultiplePumpsSpeed
Model of multiple identical pumps in parallel with speed-controlled pump model
Extends from Buildings.DHC.Plants.Combined.Subsystems.BaseClasses.PartialMultiplePumps.
Information
This model represents a set of identical speed-controlled pumps that are piped in parallel. The model may be configured to represent either constant speed pumps or variable speed pumps. An optional check valve in series with each pump is included.
Control points
The following input and output points are available.
-
Start command (VFD Run for variable speed pumps or Starter contact for constant speed pumps)
y1: DO signal dedicated to each unit, with a dimensionality of one -
(Optionally if
have_varistrue) Speed commandy: AO signal common to all units, with a dimensionality of zero -
Pump status
y1_actual: DI signal dedicated to each unit, with a dimensionality of one
Details
See the base class Buildings.DHC.Plants.Combined.Subsystems.BaseClasses.PartialMultiplePumps. for a description of the modeling approach.
