7.5.4.53 Pset_FanTypeCommon

7.5.4.53.1 Semantic definition

Fan type common attributes.

7.5.4.53.2 Applicable entities

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).
