.BuildingSystems.Fluid.HeatExchangers.ActiveBeams.Cooling

Information

Model of an active beam, based on the EnergyPlus beam model AirTerminal:SingleDuct:ConstantVolume:FourPipeBeam.

This model operates only in cooling mode. For a model that operates in both heating and cooling mode, use BuildingSystems.Fluid.HeatExchangers.ActiveBeams.CoolingAndHeating.

For a description of the equations, see the User's Guide.

Performance data are available from BuildingSystems.Fluid.HeatExchangers.ActiveBeams.Data.
