Description
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This example shows a borefield of 228 boreholes divided into 2 zones, as configured in Buildings.Fluid.Geothermal.ZonedBorefields.Data.Configuration.Validation.
The total heat flow rate is cyclical, and the flow direction reverses when the heating signal changes from injection and extraction.
