Buildings.Fluid.HeatExchangers.DXCoils.AirCooled.Examples.PerformanceCurves

Package with sevral performance curves

Information

This package contains performance curves for the cooling capacity and the EIR of air-cooled DX cooling coils that are used in the examples.

For performance data of specific air-cooled DX cooling coils, see the packages Buildings.Fluid.HeatExchangers.DXCoils.AirCooled.Data.SingleSpeed and Buildings.Fluid.HeatExchangers.DXCoils.AirCooled.Data.DoubleSpeed.

The data are described in Buildings.Fluid.HeatExchangers.DXCoils.AirCooled.Data.Generic.DXCoil.
