class Ifc4::IfcHumidifier : public Ifc4::IfcEnergyConversionDevice

A humidifier is a device that adds moisture into the air.

HISTORY New entity in IFC2x4

Type Use Definition IfcHumidifier defines the occurrence of any humidifier; common information about humidifier types is handled by IfcHumidifierType. The IfcHumidifierType (if present) may establish the common type name, usage (predefined type), properties, materials, ports, composition, assignments, and representations. The IfcHumidifierType is attached using the IfcRelDefinesByType objectified relationship and is accessible by the IsTypedBy inverse attribute. If the IfcHumidifierType has ports or aggregated elements, such objects are reflected at the IfcHumidifier 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 IfcHumidifierType, defining the common property data for all occurrences of the same type. They are then accessible by the IsTypedBy inverse attribute pointing to IfcHumidifierType.HasPropertySets. If both are given, then the properties directly defined at IfcHumidifier override the properties defined at IfcHumidifierType. 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: Pset_HumidifierPHistory (PSET_PERFORMANCEDRIVEN) Pset_HumidifierTypeCommon (PSET_TYPEDRIVENOVERRIDE)

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 IfcHumidifier 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 IfcHumidifierType, 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 IfcHumidifier are defined by IfcDistributionPort and attached by the IfcRelConnectsPortToElement relationship. If the humidifier occurrence is defined by IfcHumidifierType, then the port occurrences must reflect those defined at the IfcHumidifierType using the IfcRelDefinesByObject relationship. Ports are specific to the IfcHumidifier PredefinedType as follows indicated by the IfcDistributionPort Name, PredefinedType, and FlowDirection:

WaterIn (DOMESTICCOLDWATER, SINK): Incoming water. AirIn (AIRCONDITIONING, SINK): Incoming air. AirOut (AIRCONDITIONING, SOURCE): Outgoing air saturated with vapor.
