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. |
