Test model for cooling tower using the Merkel theory
Extends from Modelica.Icons.Example, BaseClasses.PartialStaticTwoPortCoolingTower.
Information
This example illustrates the use of the cooling tower model
Buildings.Obsolete.Fluid.HeatExchangers.CoolingTowers.Merkel.
Heat is injected into the volume vol. An on/off controller
switches the cooling loop water pump on or off based on the temperature of
this volume.
The cooling tower outlet temperature is controlled to track a fixed temperature.
