modelOpenLoopVarTSupplyDpBypass

A small open loop example with a Substation with variable dT for fixed return temperature

Extends from Modelica.Icons.Example.

Information

This is an OpenLoop example of AixLib.Fluid.DistrictHeatingCooling.Demands.OpenLoop.VarTSupplyDpBypass 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.
