IfcDuctSilencerType: public Ifc4x1::IfcFlowTreatmentDeviceType¶
The flow treatment device type IfcDuctSilencerType defines commonly shared information for occurrences of duct silencers. The set of shared information may include:
common properties with shared property sets common representations of shape common materials common composition of elements common ports applicable assignment of process types
It is used to define a duct silencer specification (i.e. the specific product information, that is common to all occurrences of that product type). Duct Silencer types may be exchanged without being already assigned to occurrences. Occurrences of IfcDuctSilencerType are represented by instances of IfcDuctSilencer.
HISTORY: New entity in IFC2x2
Property Set Use Definition The property sets relating to this entity are defined by IfcPropertySet and attached by the HasPropertySets attribute. Refer to the documentation at the supertype IfcFlowTreatmentDeviceType and ancestors for inherited property set definitions. The following property set definitions are applicable to this entity: Pset_DuctSilencerTypeCommon
Material Use Definition The material of the IfcDuctSilencerType is defined by IfcMaterialConstituentSet or as a fallback by IfcMaterial, and attached by the RelatingMaterial attribute on the IfcRelAssociatesMaterial relationship. It is accessible by the HasAssociations inverse attribute. The following keywords for IfcMaterialConstituentSet.MaterialConstituents[n].Name shall be used:
‘Body’: The primary material from which the object is constructed.
Port Use Definition The distribution ports relating to the IfcDuctSilencerType type are defined by IfcDistributionPort and attached by the IfcRelConnectsPortToElement relationship. Ports are reflected at occurrences of this type using the IfcRelDefinesByObject relationship. Refer to the documentation at IfcDuctSilencer for standard port definitions.
