| Name | Property Type | Data Type | Description | |
|---|---|---|---|---|
| AirFlowRateHistory | IfcPropertyReferenceValue | IfcTimeSeries |
Volumetric flow rate. |
|
| NeckAirVelocity | IfcPropertyReferenceValue | IfcTimeSeries |
Air velocity at the neck. |
|
| SupplyAirTemperatureHeating | IfcPropertyReferenceValue | IfcTimeSeries |
Supply air temperature in heating mode. |
|
| SupplyAirTemperatureCooling | IfcPropertyReferenceValue | IfcTimeSeries |
Supply air temperature in cooling mode. |
|
| PressureDrop | IfcPropertyReferenceValue | IfcTimeSeries |
Pressure drop. Drop in total pressure between inlet and outlet at nominal air-flow rate. |
|
| InductionRatio | IfcPropertyTableValue | IfcLengthMeasure/IfcReal |
Induction ratio versus distance from the diffuser and its discharge direction; induction ratio (or entrainment ratio) is the ratio of the volumetric flow rate in the jet to the volumetric flow rate at the air terminal. |
|
| CenterlineAirVelocity | IfcPropertyTableValue | IfcLengthMeasure/IfcLinearVelocityMeasure |
Centerline air velocity versus distance from the diffuser and temperature differential; a function of distance from diffuser and temperature difference between supply air and room air. |
