7.5.4.10 Pset_BoilerTypeSteam

7.5.4.10.1 Semantic definition

Steam boiler type common attributes.

Name Property Type Data Type Description
MaximumOutletPressure IfcPropertySingleValue IfcLabel

Maximum steam outlet pressure.

NominalEfficiencyTable IfcPropertyTableValue IfcNormalisedRatioMeasure/IfcThermodynamicTemperatureMeasure

The nominal efficiency of the boiler as defined by the manufacturer. For steam boilers, a function of inlet temperature versus steam pressure. Note: as two variables are used, DefiningValues and DefinedValues are null, and values are stored in IfcTable in the following order: InletTemperature(IfcThermodynamicTemperatureMeasure) and OutletTemperature(IfcThermodynamicTemperatureMeasure) in DefiningValues, and NominalEfficiency(IfcNormalisedRatioMeasure) in DefinedValues. For example, DefininfValues(InletTemp, OutletTemp), DefinedValues(null, NominalEfficiency). The IfcTable is related to IfcPropertyTableValue using IfcMetric and IfcResourceConstraintRelationship.

HeatOutput IfcPropertyTableValue IfcEnergyMeasure/IfcThermodynamicTemperatureMeasure

Total nominal heat output as listed by the Boiler manufacturer.

For steam boilers, it is a function of inlet temperature versus steam pressure. Note: as two variables are used, DefiningValues and DefinedValues are null, and values are stored in IfcTable in the following order: InletTemperature(IfcThermodynamicTemperatureMeasure) and OutletTemperature(IfcThermodynamicTemperatureMeasure) in DefiningValues, and HeatOutput(IfcEnergyMeasure) in DefinedValues. For example, DefiningValues(InletTemp, OutletTemp), DefinedValues(null, HeatOutput). The IfcTable is related to IfcPropertyTableValue using IfcMetric and IfcResourceConstraintRelationship.

Last change: Improve definition split (#876) * bring back headers headers were previously removed by mistake, now bringing them back * add new lines and rename the tag add the word 'short' in it * unify newlines make exactly one newline before and two after the tag * resolving typos Because bringing back headers required to go back in time to previous version, I'm now re-resolving the issues: #861, #860, #856 by ArturTomczak on 2024-07-16T16:07:28+02:00
