CoefficientOfPerformance
Semantic definition
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.
