.Buildings.DHC.ETS.Combined.Subsystems.SwitchBox

Information

This model represents a hydronic arrangement avoid flow reversal in the service line, for instance when connecting an energy transfer station such as the one modeled in Buildings.DHC.ETS.Combined.HeatPumpHeatExchanger. For that intent, two three-port two-position directional valves are used. The valves are actuated based on the logic described in Buildings.DHC.ETS.Combined.Controls.SwitchBox.
