7.5.4.71.2 Applicable entities

7.5.4.71.3 Properties

Name Property Type Data Type Description
Reference IfcPropertySingleValue IfcIdentifier

Reference ID for this specified type in this project (e.g. type 'A-1'), Also referred to as "construction type". It should be provided as an alternative to the name of the "object type", if the software does not support object types and no classification reference to a recognized classification system used.

Status IfcPropertyEnumeratedValue PEnum_ElementStatus

Status of the element, predominately used in renovation or retrofitting projects. The status can be assigned to as "New" - element designed as new addition, "Existing" - element exists and remains, "Demolish" - element existed but is to be demolished, "Temporary" - element will exists only temporary (like a temporary support structure).

HumidifierApplication IfcPropertyEnumeratedValue PEnum_HumidifierApplication

Humidifier application.

Fixed: Humidifier installed in a ducted flow distribution system. Portable: Humidifier is not installed in a ducted flow distribution system.

Weight IfcPropertySingleValue IfcMassMeasure

Total weight of object

NominalMoistureGain IfcPropertySingleValue IfcMassFlowRateMeasure

Nominal rate of water vapor added into the airstream.

NominalAirFlowRate IfcPropertySingleValue IfcVolumetricFlowRateMeasure

Nominal air flow rate.

Nominal rate of air flow into which water vapor is added.

InternalControl IfcPropertyEnumeratedValue PEnum_HumidifierInternalControl

Internal modulation control.

WaterRequirement IfcPropertySingleValue IfcVolumetricFlowRateMeasure

Make-up water requirement.

SaturationEfficiencyCurve IfcPropertyTableValue IfcNormalisedRatioMeasure/IfcVolumetricFlowRateMeasure

Saturation efficiency as a function of the air flow rate.

AirPressureDropCurve IfcPropertyTableValue IfcPressureMeasure/IfcVolumetricFlowRateMeasure

Air pressure drop as a function of air flow rate.

Air pressure drop versus air-flow rate.
