Modelica building model

On the left, a 3-zone Modelica building model generated with RoomFlex. On the right, a schematic diagram of the model with the building envelope, the components for power generation, heating and energy storage, and the home appliances.

Schematic diagram of heating components and heating circuits

Heating components

The heating circuits, including the heat storage tank, mixing valve, water pump, heating terminal and control components, are intended to reproduce the physical characteristics of the heating system as accurately as possible.
