modelHeatExchangerLocation
Test model for heat exchanger with hHex_a and hHex_b interchanged
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This validation model compares two tank models. The only difference between
the two tank models is that tan_aTop has the hot water inlet
for the heat exchanger above its outlet, whereas tan_bTop
has the hot water inlet below its outlet. In both models, the heat exchanger
extends from element 9 to element 11.
