IfcTubeBundleType

Definition from IAI: The element type IfcTubeBundleType defines a list of commonly shared property set definitions of a tube buncle and an optional set of product representations. It is used to define a tube bundle specification (i.e. the specific product information, that is common to all occurrences of that product type).

> NOTE: The product representations are defined as representation maps (at the level of the supertype IfcTypeProduct, which get assigned by an element occurrence instance through the IfcShapeRepresentation.Item[1] being an IfcMappedItem.

A tube bundle type is used to define the common properties of a tube bundle that may be applied to many occurrences of that type. 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.

The occurrences of the IfcTubeBundleType are represented by instances of IfcEnergyConversionDevice or its subtypes.
