IFC 4.3.0.1 (IFC4X3) development

7.5.4.9 Pset_BoilerTypeCommon

7.5.4.9.1 Semantic definition

Boiler type common attributes. SoundLevel attribute deleted in IFC2x2 Pset Addendum: Use IfcSoundProperties instead. PrimaryEnergySource and AuxiliaryEnergySource attributes deleted in IFC2x2 Pset Addendum: Use IfcEnergyProperties, IfcFuelProperties, etc. instead.

7.5.4.9.2 Applicable entities

7.5.4.9.3 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).

PressureRating IfcPropertySingleValue IfcPressureMeasure

Pressure rating of the object.

Nominal pressure rating of the boiler as rated by the agency having jurisdiction.

OperatingMode IfcPropertyEnumeratedValue PEnum_BoilerOperatingMode

Identifies the operating mode of the boiler.

HeatTransferSurfaceArea IfcPropertySingleValue IfcAreaMeasure

Total heat transfer area of the vessel.

NominalPartLoadRatio IfcPropertyBoundedValue IfcReal

Allowable part load ratio range.

WaterInletTemperatureRange IfcPropertyBoundedValue IfcThermodynamicTemperatureMeasure

Allowable water inlet temperature range.

WaterStorageCapacity IfcPropertySingleValue IfcVolumeMeasure

Water storage capacity.

IsWaterStorageHeater IfcPropertySingleValue IfcBoolean

This is used to identify if the boiler has storage capacity (TRUE). If FALSE, then there is no storage capacity built into the boiler, such as an instantaneous hot water heater.

PartialLoadEfficiencyCurves IfcPropertyTableValue IfcNormalisedRatioMeasure/IfcPositiveRatioMeasure

Boiler efficiency as a function of the partial load factor; E = f (partialLaodfactor).

OutletTemperatureRange IfcPropertyBoundedValue IfcThermodynamicTemperatureMeasure

Allowable outlet temperature of either the water or the steam.

NominalEnergyConsumption IfcPropertySingleValue IfcPowerMeasure

Nominal fuel consumption rate required to produce the total boiler heat output.

EnergySource IfcPropertyEnumeratedValue PEnum_EnergySource

Enumeration defining the energy source or fuel cumbusted.
