.Buildings.DHC.Plants.Combined.Subsystems.MultiplePumpsSpeed

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_var is true) Speed command y: 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.
