modelDryCoilEffectivenessNTU
Model that demonstrates use of a heat exchanger without condensation that uses the epsilon-NTU relation
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This model tests Buildings.Fluid.HeatExchangers.DryCoilEffectivenessNTU for different inlet conditions.
