modelMultiplePumpsFlow
Model of multiple identical pumps in parallel with flow-controlled pump model
Extends from BaseClasses.PartialMultiplePumps.
Information
This model represents a set of identical flow-controlled variable speed pumps that are piped in parallel. 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)
y1: DO signal dedicated to each unit, with a dimensionality of one -
(Optionally if
have_varSetistrue) Mass flow rate setpointm_flow_in: AO signal with a dimensionality of zero The setpoint corresponds to the total flow rate of all units. -
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.
Parameters
| Type | Name | Default | Description |
