Buildings.Fluid.HeatExchangers.DXCoils.BaseClasses.Examples.PerformanceCurves
Package with sevral performance curves
Information
This package contains performance curves for the cooling capacity and the EIR of DX cooling coils that are used in the examples.
For performance data of specific DX cooling coils, see the packages Buildings.Fluid.HeatExchangers.DXCoils.Data.SingleSpeed and Buildings.Fluid.HeatExchangers.DXCoils.Data.DoubleSpeed.
The data are described in Buildings.Fluid.HeatExchangers.DXCoils.Data.Generic.DXCoil.
