Heat Storage Water Heater

Stratified tank with an internal heat exchanger and ambient heat losses (nodal model)


Nodal model of a stratified tank, with the following hypotheses:

  • No heat transfer between the different nodes
  • The internal heat exchanger is discretized in the same way as the tank: each cell of the heat exchanger corresponds to one cell of the tank and exchanges heat with that cell only.
  • Incompressible fluid in both the tank and the heat exchanger

The tank is discretized using a modified version of the incompressible Cell1Dim model adding an additional heat port. The heat exchanger is modeled using the Flow1Dim component and a wall component.
