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 copied from the Buildings library 10.0.0
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.
