Description
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This validation cases tests the independent operation of borefield zones for the borefield configured in Buildings.Fluid.Geothermal.ZonedBorefields.Data.Configuration.Validation.
The heating rate to a zone is constant (when activated). The duration of heat injection into each zone is a multiple of 1 month, with alternating signals to each zone to obtain all possible combinations of activated and deactivated zones.
