CoefficientOfPerformanceCurve

Semantic definition

Chiller coefficient of performance (COP) is function of condensing temperature and evaporating temperature, data is in table form, COP= f (TempCon, TempEvp), COP = a2+b2*Tei+c2*Tei\^2+d2*Tci+e2*Tci\^2+f2*Tei*Tci. This table uses multiple input variables; to represent, both DefiningValues and DefinedValues lists are null and IfcTable is attached using IfcResourceConstraintRelationship and IfcMetric. Columns are specified in the following order: 1.IfcPositiveRatioMeasure:CoefficientOfPerformance 2.IfcThermodynamicTemperatureMeasure:CondensingTemperature 3.IfcThermodynamicTemperatureMeasure:EvaporatingTemperature
