7.5.4.56 Pset_FilterTypeCommon

7.5.4.56.1 Semantic definition

Filter type common attributes.

7.5.4.56.2 Applicable entities

7.5.4.56.3 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).

Weight IfcPropertySingleValue IfcMassMeasure

Total weight of object

InitialResistance IfcPropertySingleValue IfcPressureMeasure

Initial new filter fluid resistance (i.e., pressure drop at the maximum air flowrate across the filter when the filter is new per ASHRAE Standard 52.1).

FinalResistance IfcPropertySingleValue IfcPressureMeasure

Filter fluid resistance when replacement is required (i.e., Pressure drop at the maximum air flowrate across the filter when the filter needs replacement per ASHRAE Standard 52.1).

OperationTemperatureRange IfcPropertyBoundedValue IfcThermodynamicTemperatureMeasure

Allowable operation ambient air temperature range.

FlowRateRange IfcPropertyBoundedValue IfcVolumetricFlowRateMeasure

Allowable range of volume of fluid being pumped against the resistance specified.

NominalFilterFaceVelocity IfcPropertySingleValue IfcLinearVelocityMeasure

Filter face velocity.

NominalMediaSurfaceVelocity IfcPropertySingleValue IfcLinearVelocityMeasure

Average fluid velocity at the media surface.

NominalPressureDrop IfcPropertySingleValue IfcPressureMeasure

Total pressure drop across the filter.

NominalFlowrate IfcPropertySingleValue IfcVolumetricFlowRateMeasure

Nominal fluid flow rate through the filter.

NominalParticleGeometricMeanDiameter IfcPropertySingleValue IfcPositiveLengthMeasure

Particle geometric mean diameter associated with nominal efficiency.

NominalParticleGeometricStandardDeviation IfcPropertySingleValue IfcReal

Particle geometric standard deviation associated with nominal efficiency.
