Evaporative cooler type common attributes. Sound attribute deleted in IFC2x2 Pset Addendum: Use IfcSoundProperties instead. WaterRequirement attribute unit type modified in IFC2x2 Pset Addendum.

7.5.4.47.2 Applicable entities

7.5.4.47.3 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).

FlowArrangement IfcPropertyEnumeratedValue PEnum_EvaporativeCoolerFlowArrangement

Defines the basic flow arrangements for the heat exchanger or cooler tower:

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. MULTIPASS: Multipass flow heat exchanger arrangement. OTHER: Other type of heat exchanger flow arrangement not defined above.

HeatExchangeArea IfcPropertySingleValue IfcAreaMeasure

Heat exchange area.

OperationTemperatureRange IfcPropertyBoundedValue IfcThermodynamicTemperatureMeasure

Allowable operation ambient air temperature range.

WaterRequirement IfcPropertySingleValue IfcVolumetricFlowRateMeasure

Make-up water requirement.

EffectivenessTable IfcPropertyTableValue IfcReal/IfcVolumetricFlowRateMeasure

Total heat transfer effectiveness curve as a function of the primary air flow rate.

AirPressureDropCurve IfcPropertyTableValue IfcPressureMeasure/IfcVolumetricFlowRateMeasure

Air pressure drop as a function of air flow rate.

WaterPressDropCurve IfcPropertyTableValue IfcPressureMeasure/IfcVolumetricFlowRateMeasure

Water pressure drop as function of water flow rate.
