Curve_I

Information

This record declares performance curves for the cooling capacity and the EIR. It has been obtained from the EnergyPlus 8.6 example file UnitarySystem_VSHeatPumpWaterToAirEquationFit.idf.

Extends from Buildings.Fluid.DXSystems.Cooling.WaterSource.Data.Generic.BaseClasses.PerformanceCurve (Data record for a performance curve).
