modelStepResponseEpsilonNTU

Model that tests the radiant slab with epsilon-NTU configuration

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

Information

This model is identical to Buildings.Fluid.HeatExchangers.RadiantSlabs.Examples.StepResponseFiniteDifference except that the number of segments in the slab is set to 1 and the heat transfer between the fluid and the slab is computed using an epsilon-NTU model.
