IFC (IFC4X3_ADD2) under development Pset_DistributionPortPHistoryDuct Semantic definition

Fluid flow performance history attached to an instance of IfcPerformanceHistory assigned to IfcDistributionPort. This replaces the deprecated IfcFluidFlowProperties for performance values. Applicable entities Properties

Name Property Type Data Type Description
TemperatureHistory IfcPropertyReferenceValue IfcTimeSeries

Temperature of the fluid. For air this value represents the dry bulb temperature.

WetBulbTemperatureHistory IfcPropertyReferenceValue IfcTimeSeries

Wet bulb temperature of the fluid; only applicable if the fluid is air.

VolumetricFlowRateHistory IfcPropertyReferenceValue IfcTimeSeries

The volumetric flow rate of the fluid.

MassFlowRateHistory IfcPropertyReferenceValue IfcTimeSeries

The mass flow rate of the fluid.

FlowConditionHistory IfcPropertyReferenceValue IfcTimeSeries

Defines the flow condition as a percentage of the cross-sectional area.

VelocityHistory IfcPropertyReferenceValue IfcTimeSeries

The velocity of the fluid.

PressureHisotry IfcPropertyReferenceValue IfcTimeSeries

The pressure of the fluid.
