Buildings.Fluid.HeatExchangers.ActiveBeams.BaseClasses.Examples.Convector

Information

The example tests the implementation of Buildings.Fluid.HeatExchangers.ActiveBeams.BaseClasses.Convector. The room air temperature and the water mass flow rate are constant while the air flow rate varys with a ramp.

Extends from Modelica.Icons.Example (Icon for runnable examples).

Buildings.Fluid.HeatExchangers.ActiveBeams.BaseClasses.Examples.DerivateCubicSpline

Information

The example tests the implementation of Buildings.Fluid.HeatExchangers.ActiveBeams.BaseClasses.DerivativesCubicSpline. Default vectors are: x=[0,0.5,1] and y=[0,0.75,1]. Input to the model is the simulation time.
