IfcEvaporator: public Ifc4x3_rc1::IfcEnergyConversionDevice¶
An evaporator is a device in which a liquid refrigerent is vaporized and absorbs heat from the surrounding fluid.
HISTORY New entity in IFC2x4
Type Use Definition IfcEvaporator defines the occurrence of any evaporator; common information about evaporator types is handled by IfcEvaporatorType. The IfcEvaporatorType (if present) may establish the common type name, usage (predefined type), properties, materials, ports, composition, assignments, and representations. The IfcEvaporatorType is attached using the IfcRelDefinesByType objectified relationship and is accessible by the IsTypedBy inverse attribute. If the IfcEvaporatorType has ports or aggregated elements, such objects are reflected at the IfcEvaporator 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 IfcEvaporatorType, defining the common property data for all occurrences of the same type. They are then accessible by the IsTypedBy inverse attribute pointing to IfcEvaporatorType.HasPropertySets. If both are given, then the properties directly defined at IfcEvaporator override the properties defined at IfcEvaporatorType. 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_EvaporatorPHistory (PSET_PERFORMANCEDRIVEN) Pset_EvaporatorTypeCommon (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.
Material Use Definition The material of the IfcEvaporator 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 IfcEvaporatorType, 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 IfcEvaporator are defined by IfcDistributionPort and attached by the IfcRelConnectsPortToElement relationship. If the evaporator occurrence is defined by IfcEvaporatorType, then the port occurrences must reflect those defined at the IfcEvaporatorType using the IfcRelDefinesByObject relationship. Ports are specific to the IfcEvaporator PredefinedType as follows indicated by the IfcDistributionPort Name, PredefinedType, and FlowDirection:
RefrigerantIn (REFRIGERATION, SINK): Liquid refrigerant entering the evaporator. RefrigerantOut (REFRIGERATION, SOURCE): Vapor refrigerant leaving the evaporator. AirIn (AIRCONDITIONING, SINK): Air return entering the evaporator. AirOut (AIRCONDITIONING, SOURCE): Air supply leaving the evaporator.
RefrigerantIn (REFRIGERATION, SINK): Liquid refrigerant entering the evaporator. RefrigerantOut (REFRIGERATION, SOURCE): Vapor refrigerant leaving the evaporator. ChilledWaterIn (CHILLEDWATER, SINK): Chilled water return entering the evaporator. ChilledWaterOut (CHILLEDWATER, SOURCE): Chilled water supply leaving the evaporator. ChilledWaterIn (CHILLEDWATER, SINK): Chilled water return entering the evaporator. ChilledWaterOut (CHILLEDWATER, SOURCE): Chilled water supply leaving the evaporator.
RefrigerantIn (REFRIGERATION, SINK): Liquid refrigerant entering the evaporator. RefrigerantOut (REFRIGERATION, SOURCE): Vapor refrigerant leaving the evaporator.
