.BuildingSystems.Fluid.Movers.BaseClasses.Characteristics

Information

This package implements performance curves for fans and pumps, and records for parameter that can be used with these performance curves.

See the User's Guide for information about these performance curves.

Contents

Name	Description
efficiency	Flow vs. efficiency characteristics for fan or pump
efficiency_yMot	Efficiency vs. motor PLR characteristics for fan or pump
motorEfficiencyCurve	This function generates the generic curve for motor efficiency based on rated motor power
power	Flow vs. electrical power characteristics for fan or pump
pressure	Pump or fan head away from the origin without correction for mover flow resistance
efficiencyParameters	Record for efficiency parameters vs. volumetric flow rate
efficiencyParameters_yMot	Record for efficiency parameters vs. motor part load ratio
flowParameters	Record for flow parameters
flowParametersInternal	Record for flow parameters with prescribed size
powerParameters	Record for electrical power parameters

Revisions

• September 8, 2016, by Michael Wetter:
  Deleted function performanceCurve as it is no longer needed. Instead, the function BuildingSystems.Fluid.Movers.BaseClasses.Characteristics.pressure is used for all speeds.
  This is for #458.
• September 29, 2011, by Michael Wetter:
  New implementation due to changes from polynomial to cubic hermite splines.
