7.5.4.53.3 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). |
|
| MotorDriveType | IfcPropertyEnumeratedValue | PEnum_FanMotorConnectionType |
Motor drive type: DIRECTDRIVE: Direct drive. BELTDRIVE: Belt drive. COUPLING: Coupling. OTHER: Other type of motor drive. UNKNOWN: Unknown motor drive type. |
|
| CapacityControlType | IfcPropertyEnumeratedValue | PEnum_FanCapacityControlType |
InletVane: Control by adjusting inlet vane. VariableSpeedDrive: Control by variable speed drive. BladePitchAngle: Control by adjusting blade pitch angle. TwoSpeed: Control by switch between high and low speed. DischargeDamper: Control by modulating discharge damper. |
|
| OperationTemperatureRange | IfcPropertyBoundedValue | IfcThermodynamicTemperatureMeasure |
Allowable operation ambient air temperature range. |
|
| NominalAirFlowRate | IfcPropertySingleValue | IfcVolumetricFlowRateMeasure |
Nominal air flow rate. |
|
| NominalTotalPressure | IfcPropertySingleValue | IfcPressureMeasure |
Nominal total pressure rise across the fan. |
|
| NominalStaticPressure | IfcPropertySingleValue | IfcPressureMeasure |
The static pressure within the air stream that the fan must overcome to insure designed circulation of air. |
|
| NominalRotationSpeed | IfcPropertySingleValue | IfcRotationalFrequencyMeasure |
Rotational speed of the object under nominal conditions. Nominal fan wheel speed. |
|
| NominalPowerRate | IfcPropertySingleValue | IfcPowerMeasure |
Nominal fan power rate. |
|
| OperationalCriteria | IfcPropertySingleValue | IfcTimeMeasure |
Time of operation at maximum operational ambient air temperature. |
|
| PressureCurve | IfcPropertyTableValue | IfcPressureMeasure/IfcVolumetricFlowRateMeasure |
Pressure rise = f (flow rate). |
|
| EfficiencyCurve | IfcPropertyTableValue | IfcNormalisedRatioMeasure/IfcVolumetricFlowRateMeasure |
Fan efficiency =f (flow rate). |
