Reference P_SINGLEVALUE / IfcIdentifier *
BauteiltypBezeichnung zur Zusammenfassung gleichartiger Bauteile zu einem Bauteiltyp (auch Konstruktionstyp genannt). Alternativ zum Namen des "Typobjekts", insbesondere wenn die Software keine Typen unterstützt.
ReferenceReference 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.
ReferenceRéférence à l'identifiant d'un type spécifié dans le contexte du projet (exemple : "type A1") pour désigner un "type de construction". Une alternative au nom d'un objet type lorsque les objets types ne sont pas gérés par le logiciel.
Status P_ENUMERATEDVALUE / IfcLabel / PEnum_ElementStatus*
StatusStatus bzw. Phase des Bauteils insbesondere beim Bauen im Bestand. "Neu" (new) neues Bauteil als Ergänzung, "Bestand" (existing) bestehendes Bauteil, dass erhalten bleibt, "Abbruch" (demolish) Bauteil, das abgebrochen wird, "Temporär" (temporary) Bauteil und andere Bauelemente, die vorübergehend eingebaut werden (wie Abstützungen, etc.)
StatusStatus 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).
StatutStatut de l'élément, principalement utilisé dans les projets de rénovation et de réhabilitation. Le statut a pour valeur NOUVEAU pour un nouvel élément, EXISTANT pour un élément existant qui est conservé, DEMOLI pour un élément existant à démolir et TEMPORAIRE pour un élément temporaire (comme une structure support provisoire).
状態要素(主にリノベーションまたは改修プロジェクトにおいて)の状態。 状態は、「新規(New)」-新しく追加される要素。「既存」-要素は存在し、かつ残りもの。「破壊」-要素は存在したが、廃棄されるもの。「一時的」-一時的に存在する要素(一時的にサポートしている構造のようなもの)。
NominalCapacity P_SINGLEVALUE / IfcPowerMeasure
Nominal CapacityNominal cooling tower capacity in terms of heat transfer rate of the cooling tower between air stream and water stream at nominal conditions.
CircuitType P_ENUMERATEDVALUE / IfcLabel / PEnum_CoolingTowerCircuitType
Circuit TypeOpenCircuit: Exposes water directly to the cooling atmosphere. CloseCircuit: The fluid is separated from the atmosphere by a heat exchanger. Wet: The air stream or the heat exchange surface is evaporatively cooled. Dry: No evaporation into the air stream. DryWet: A combination of a dry tower and a wet tower.
FlowArrangement P_ENUMERATEDVALUE / IfcLabel / PEnum_CoolingTowerFlowArrangement
Flow ArrangementCounterFlow: Air and water flow enter in different directions. CrossFlow: Air and water flow are perpendicular. ParallelFlow: air and water flow enter in same directions.
SprayType P_ENUMERATEDVALUE / IfcLabel / PEnum_CoolingTowerSprayType
Spray TypeSprayFilled: Water is sprayed into airflow. SplashTypeFill: water cascades over successive rows of splash bars. FilmTypeFill: water flows in a thin layer over closely spaced sheets.
CapacityControl P_ENUMERATEDVALUE / IfcLabel / PEnum_CoolingTowerCapacityControl
Capacity ControlFanCycling: Fan is cycled on and off to control duty. TwoSpeedFan: Fan is switched between low and high speed to control duty. VariableSpeedFan: Fan speed is varied to control duty. DampersControl: Dampers modulate the air flow to control duty. BypassValveControl: Bypass valve modulates the water flow to control duty. MultipleSeriesPumps: Turn on/off multiple series pump to control duty. TwoSpeedPump: Switch between high/low pump speed to control duty. VariableSpeedPump: vary pump speed to control duty.
ControlStrategy P_ENUMERATEDVALUE / IfcLabel / PEnum_CoolingTowerControlStrategy
Control StrategyFixedExitingWaterTemp: The capacity is controlled to maintain a fixed exiting water temperature. WetBulbTempReset: The set-point is reset based on the wet-bulb temperature.
NumberOfCells P_SINGLEVALUE / IfcInteger
Number Of CellsNumber of cells in one cooling tower unit.
BasinReserveVolume P_SINGLEVALUE / IfcVolumeMeasure
Basin Reserve VolumeVolume between operating and overflow levels in cooling tower basin.
LiftElevationDifference P_SINGLEVALUE / IfcPositiveLengthMeasure
Lift Elevation DifferenceElevation difference between cooling tower sump and the top of the tower.
WaterRequirement P_SINGLEVALUE / IfcVolumetricFlowRateMeasure
Water RequirementMake-up water requirements.
OperationTemperatureRange P_SINGLEVALUE / IfcThermodynamicTemperatureMeasure
Operation Temperature RangeAllowable operation ambient air temperature range.
AmbientDesignDryBulbTemperature P_SINGLEVALUE / IfcThermodynamicTemperatureMeasure
Ambient Design Dry Bulb TemperatureAmbient design dry bulb temperature used for selecting the cooling tower.
AmbientDesignWetBulbTemperature P_SINGLEVALUE / IfcThermodynamicTemperatureMeasure
Ambient Design Wet Bulb TemperatureAmbient design wet bulb temperature used for selecting the cooling tower.
