modelTestHeatExchanger

Test model for the heat exchanger

Extends from TransiEnt.Basics.Icons.Checkmodel (Icon for check models).

Information

Purpose of model:

Test model for the verification of the heat exchanger model.

Compare this variables for the verification of the heat exchanger

heatExchanger.T_in

heatExchanger.T_out

idealShell_L2_1.fluidIn.T

idealShell_L2_1.fluidOut.T

idealShell_L2_2.fluidOut.T

heatExchanger.heatPort.Q_flow

idealShell_L2_1.heat.Q_flow

For physical behaviour check difference between

idealShell_L2_1.fluidOut.T

idealShell_L2_2.fluidOut.T

one uses a logarithmic temperature difference and one a temperature difference based on the return temperature
