This model represents a change-over system where the configuration Buildings.Fluid.HydronicConfigurations.ActiveNetworks.Decoupling serves as the interface between a variable flow primary circuit and a variable flow consumer circuit operated in change-over. For a given operating mode, both the primary circuit and the consumer circuit have a constant supply temperature.
The model illustrates how the primary flow rate varies with the secondary flow rate, yielding a nearly constant bypass mass flow rate.
