Reference

P_SINGLEVALUE / IfcIdentifier *

| Bauteiltyp | Bezeichnung zur Zusammenfassung gleichartiger Bauteile zu einem Bauteiltyp (auch Konstruktionstyp genannt). Alternativ zum Namen des "Typobjekts", insbesondere wenn die Software keine Typen unterstützt.
| Reference | 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.
| Reference | Référence 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.
| 参照記号 | このプロジェクトにおける参照記号(例：A-1)。分類コードではなく内部で使用されるプロジェクトタイプとして使用されるもの。
| 参考号 | 若未采用已知的分类系统，则该属性为该项目中该类型构件的参考编号（例如，类型A-1）。

Status

P_ENUMERATEDVALUE / IfcLabel / PEnum_ElementStatus*

| Status | Status 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.)
| Status | 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).
| Statut | Statut 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 Capacity | Nominal 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 Type | OpenCircuit: 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 Arrangement | CounterFlow: 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 Type | SprayFilled: 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 Control | FanCycling: 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 Strategy | FixedExitingWaterTemp: 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 Cells | Number of cells in one cooling tower unit.

BasinReserveVolume

P_SINGLEVALUE / IfcVolumeMeasure

| Basin Reserve Volume | Volume between operating and overflow levels in cooling tower basin.

LiftElevationDifference

P_SINGLEVALUE / IfcPositiveLengthMeasure

| Lift Elevation Difference | Elevation difference between cooling tower sump and the top of the tower.

WaterRequirement

P_SINGLEVALUE / IfcVolumetricFlowRateMeasure

| Water Requirement | Make-up water requirements.

OperationTemperatureRange

P_SINGLEVALUE / IfcThermodynamicTemperatureMeasure

| Operation Temperature Range | Allowable operation ambient air temperature range.

AmbientDesignDryBulbTemperature

P_SINGLEVALUE / IfcThermodynamicTemperatureMeasure

| Ambient Design Dry Bulb Temperature | Ambient design dry bulb temperature used for selecting the cooling tower.

AmbientDesignWetBulbTemperature

P_SINGLEVALUE / IfcThermodynamicTemperatureMeasure

| Ambient Design Wet Bulb Temperature | Ambient design wet bulb temperature used for selecting the cooling tower.
