modelOpenLoopHeatPumpCarnot
A small open loop example with a heat pump in the substation
Extends from Modelica.Icons.Example.
Information
This is similar to the OpenLoopCooling example, but demonstrates a very simple pressure control.
This is an OpenLoop example of AixLib.Fluid.DistrictHeatingCooling.Demands.OpenLoop.VarTSupplyDp which is a simple substation model using a fixed return temperature and the actual supply temperature to calculate the mass flow rate drawn from the network.
This model uses an open loop design to prescribe the required flow rate.This model includes a heat pump model using the district heating network as its source.
