7.5.4.13.3 Properties
| Name | Property Type | Data Type | Description | |
|---|---|---|---|---|
| Capacity | IfcPropertyReferenceValue | IfcTimeSeries |
The capacity of the element. The product of the ideal capacity and the overall volumetric efficiency of the compressor. |
|
| EnergyEfficiencyRatio | IfcPropertyReferenceValue | IfcTimeSeries |
Energy efficiency ratio (EER). Ratio of net cooling capacity to the total input rate of electric power applied. By definition, the units are BTU/hour per Watt. The input electric power may be obtained from Pset_DistributionPortPHistoryElectrical.RealPower on the 'Power' port of the IfcChiller. |
|
| CoefficientOfPerformance | IfcPropertyReferenceValue | IfcTimeSeries |
The Coefficient of performance (COP) is the ratio of heat removed to energy input. The energy input may be obtained by multiplying Pset_DistributionPortPHistoryGas.FlowRate on the 'Fuel' port of the IfcChiller by Pset_MaterialFuel.LowerHeatingValue. The IfcDistributionPort for fuel has an associated IfcMaterial with fuel properties and is assigned to an IfcPerformanceHistory object nested within this IfcPerformanceHistory object. |
