modelPlateHeatExchangerEffectivenessNTUPControl

Model that demonstrates use of a plate heat exchanger without condensation that uses the epsilon-NTU relation with feedback control

Extends from Modelica.Icons.Example (Icon for runnable examples).

Information

This model demonstrates the use of Buildings.Fluid.HeatExchangers.PlateHeatExchangerEffectivenessNTU. The valve on the water-side is regulated to track a setpoint temperature for the water outlet.
