IfcSpaceHeaterType

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

> NOTE: This entity subsumes the entities IfcHydronicHeater and IfcUnitHeater from IFC R2x.

> 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 space heater type is used to define the common properties of a space heater device that may be applied to many occurrences of that type. Space heaters utilize a combination of radiation and/or natural convection using a heating source such as steam or hot water. Examples of space heaters include radiators, convectors, baseboard and finned-tube heaters, etc. Space heater types (or the instantiable subtypes) may be exchanged without being already assigned to occurrences.

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

Property Set Use Definition:

The property sets relating to this entity are defined by the IfcPropertySet and attached by the IfcRelDefinesByProperties relationship. It is accessible by the inverse IsDefinedBy relationship. The following property set definitions specific to this entity are part of this IFC release:

- Pset_SpaceHeaterTypeCommon: common property set for all space heater types

- Pset_SpaceHeaterTypeHydronic: property set for all hydronic space heater types

> HISTORY: New entity in IFC Release 2x2.
