7.5.4.20.3 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).

PowerSource IfcPropertyEnumeratedValue PEnum_CompressorTypePowerSource

Type of power driving the compressor.

RefrigerantClass IfcPropertyEnumeratedValue PEnum_RefrigerantClass

Refrigerant class used by the object. CFC: Chlorofluorocarbons. HCFC: Hydrochlorofluorocarbons. HFC: Hydrofluorocarbons.

MinimumPartLoadRatio IfcPropertySingleValue IfcPositiveRatioMeasure

Minimum part load ratio as a fraction of nominal capacity.

MaximumPartLoadRatio IfcPropertySingleValue IfcPositiveRatioMeasure

Maximum part load ratio as a fraction of nominal capacity.

CompressorSpeed IfcPropertySingleValue IfcRotationalFrequencyMeasure

Compressor speed.

NominalCapacity IfcPropertySingleValue IfcPowerMeasure

The total nominal or volumetric capacity of the object.

Compressor nameplate capacity.

IdealCapacity IfcPropertySingleValue IfcPowerMeasure

Compressor capacity under ideal conditions.

IdealShaftPower IfcPropertySingleValue IfcPowerMeasure

Compressor shaft power under ideal conditions.

HasHotGasBypass IfcPropertySingleValue IfcBoolean

Whether or not hot gas bypass is provided for the compressor. TRUE = Yes, FALSE = No.

ImpellerDiameter IfcPropertySingleValue IfcPositiveLengthMeasure

Diameter of object - used to scale performance of geometrically similar objects.
