class Ifc4x1::IfcTubeBundle : public Ifc4x1::IfcEnergyConversionDevice

A tube bundle is a device consisting of tubes and bundles of tubes used for heat transfer and contained typically within other energy conversion devices, such as a chiller or coil.

HISTORY New entity in IFC2x4

Type Use Definition IfcTubeBundle defines the occurrence of any tube bundle; common information about tube bundle types is handled by IfcTubeBundleType. The IfcTubeBundleType (if present) may establish the common type name, usage (predefined type), properties, materials, ports, composition, assignments, and representations. The IfcTubeBundleType is attached using the IfcRelDefinesByType objectified relationship and is accessible by the IsTypedBy inverse attribute. If the IfcTubeBundleType has ports or aggregated elements, such objects are reflected at the IfcTubeBundle occurrence using the IfcRelDefinesByObject relationship.

Property Use Definition The property sets relating to this entity are defined by IfcPropertySet and attached by the IfcRelDefinesByProperties relationship. They are accessible by the IsDefinedBy inverse attribute. Property sets may also be specified at the IfcTubeBundleType, defining the common property data for all occurrences of the same type. They are then accessible by the IsTypedBy inverse attribute pointing to IfcTubeBundleType.HasPropertySets. If both are given, then the properties directly defined at IfcTubeBundle override the properties defined at IfcTubeBundleType. Refer to the documentation at the supertype IfcEnergyConversionDevice and ancestors for inherited property set definitions. The following property set definitions are applicable to this entity: (All Types)




Quantity Use Definition The quantities relating to this entity are defined by IfcElementQuantity and attached by the IfcRelDefinesByProperties relationship. They are accessible by the IsDefinedBy inverse attribute. The following base quantities are defined and shall be exchanged with the IfcElementQuantity.Name = ‘BaseQuantities’. Other quantities, being subjected to local standard of measurement, may be defined with another string value assigned to Name. In this case a valid value for MethodOfMeasurement shall be provided.


Material Use Definition The material of the IfcTubeBundle 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. Material information can also be given at the IfcTubeBundleType, defining the common attribute data for all occurrences of the same type. 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 IfcTubeBundle are defined by IfcDistributionPort and attached by the IfcRelConnectsPortToElement relationship. If the tube bundle occurrence is defined by IfcTubeBundleType, then the port occurrences must reflect those defined at the IfcTubeBundleType using the IfcRelDefinesByObject relationship. Ports are specific to the IfcTubeBundle PredefinedType as follows indicated by the IfcDistributionPort Name, PredefinedType, and FlowDirection:

Inlet (NOTDEFINED, SINK): Inlet. Outlet (NOTDEFINED, SOURCE): Outlet.
