modelCarnot_TCon
Test model for heat pump based on Carnot efficiency and condenser outlet temperature control signal
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
Example that simulates a chiller whose efficiency is scaled based on the
Carnot cycle.
The chiller takes as an input the evaporator leaving water temperature.
The condenser mass flow rate is computed in such a way that it has
a temperature difference equal to dTEva_nominal.
