class Ifc4x2::IfcCondenser : public Ifc4x2::IfcEnergyConversionDevice

A condenser is a device that is used to dissipate heat, typically by condensing a substance such as a refrigerant from its gaseous to its liquid state.

HISTORY New entity in IFC2x4

Type Use Definition IfcCondenser defines the occurrence of any condenser; common information about condenser types is handled by IfcCondenserType. The IfcCondenserType (if present) may establish the common type name, usage (predefined type), properties, materials, ports, composition, assignments, and representations. The IfcCondenserType is attached using the IfcRelDefinesByType objectified relationship and is accessible by the IsTypedBy inverse attribute. If the IfcCondenserType has ports or aggregated elements, such objects are reflected at the IfcCondenser occurrence using the IfcRelDefinesByObject relationship.

Property Use Definition The property sets relating to this entity are defined by IfcPropertySet and attached by the IfcRelDefinesByProperties relationship. They are accessible by the IsDefinedBy inverse attribute. Property sets may also be specified at the IfcCondenserType, defining the common property data for all occurrences of the same type. They are then accessible by the IsTypedBy inverse attribute pointing to IfcCondenserType.HasPropertySets. If both are given, then the properties directly defined at IfcCondenser override the properties defined at IfcCondenserType. Refer to the documentation at the supertype IfcEnergyConversionDevice and ancestors for inherited property set definitions. The following property set definitions are applicable to this entity: Pset_CondenserPHistory (PSET_PERFORMANCEDRIVEN) Pset_CondenserTypeCommon (PSET_TYPEDRIVENOVERRIDE)

Quantity Use Definition The quantities relating to this entity are defined by IfcElementQuantity and attached by the IfcRelDefinesByProperties relationship. They are accessible by the IsDefinedBy inverse attribute. The following base quantities are defined and shall be exchanged with the IfcElementQuantity.Name = ‘BaseQuantities’. Other quantities, being subjected to local standard of measurement, may be defined with another string value assigned to Name. In this case a valid value for MethodOfMeasurement shall be provided.

Qto_CondenserBaseQuantities

Material Use Definition The material of the IfcCondenser is defined by IfcMaterialConstituentSet or as a fallback by IfcMaterial, and attached by the RelatingMaterial attribute on the IfcRelAssociatesMaterial relationship. It is accessible by the HasAssociations inverse attribute. Material information can also be given at the IfcCondenserType, defining the common attribute data for all occurrences of the same type. The following keywords for IfcMaterialConstituentSet.MaterialConstituents[n].Name shall be used:

Body: The primary material from which the object is constructed. Refrigerant: Refrigerant material.

Port Use Definition The distribution ports relating to the IfcCondenser are defined by IfcDistributionPort and attached by the IfcRelConnectsPortToElement relationship. If the condenser occurrence is defined by IfcCondenserType, then the port occurrences must reflect those defined at the IfcCondenserType using the IfcRelDefinesByObject relationship. Ports are specific to the IfcCondenser PredefinedType as follows indicated by the IfcDistributionPort Name, PredefinedType, and FlowDirection:

AIRCOOLED

RefrigerantIn (REFRIGERATION, SINK): Vapor refrigerant entering the condenser. RefrigerantOut (REFRIGERATION, SOURCE): Liquid refrigerant leaving the condenser. CompressedAirIn (COMPRESSEDAIR, SINK): Cooler air entering the condenser. CompressedAirOut (COMPRESSEDAIR, SOURCE): Warmer air leaving the condenser.

EVAPORATIVECOOLED

RefrigerantIn (REFRIGERATION, SINK): Vapor refrigerant entering the condenser. RefrigerantOut (REFRIGERATION, SOURCE): Liquid refrigerant leaving the condenser. CondenserWaterIn (CONDENSERWATER, SINK): Makeup water entering the condenser. CondenserWaterOut (CONDENSERWATER, SOURCE): Purged water leaving the condenser. VentilationIn (VENTILATION, SINK): Air entering the condenser. VentilationOut (VENTILATION, SOURCE): Air leaving the condenser.

WATERCOOLED

RefrigerantIn (REFRIGERATION, SINK): Vapor refrigerant entering the condenser. RefrigerantOut (REFRIGERATION, SOURCE): Liquid refrigerant leaving the condenser. CondenserWaterIn (CONDENSERWATER, SINK): Cooler water entering the condenser, optionally from cooling tower. CondenserWaterOut (CONDENSERWATER, SOURCE): Warmer water leaving the condenser, optionally to cooling tower.
