modelBuildingRCZ1Valve
One-zone RC building model with distribution pumps and mixing valves
Extends from Buildings.DHC.Loads.BaseClasses.PartialBuilding.
Information
This is a simplified one-zone building model based on a one-element reduced order room model. The corresponding heating and cooling loads are computed with a four-pipe fan coil unit model derived from Buildings.DHC.Loads.BaseClasses.PartialTerminalUnit and connected to the room model by means of fluid ports.
The heating and chilled water distribution to the terminal units is modeled with an instance of Buildings.DHC.Loads.BaseClasses.FlowDistribution including a mixing valve to control the supply temperature.
