modelSingleCircuitMultipleCircuitEpsilonNTU
Model that tests the radiant slab with multiple parallel circuits and epsilon-NTU configuration
Extends from Modelica.Icons.Example.
Information
This model is identical to Buildings.Fluid.HeatExchangers.RadiantSlabs.Examples.SingleCircuitMultipleCircuitFiniteDifference 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.
