Annex60.Fluid.FMI.ExportContainers.Examples.FMUs.HVACZone

Declaration of an FMU that exports a simple convective only HVAC system

Annex60.Fluid.FMI.ExportContainers.Examples.FMUs.HVACZone

Information

This example demonstrates how to export a model of an HVAC system that only provides convective cooling to a single thermal zone. The HVAC system is adapted from Annex60.Examples.Tutorial.SpaceCooling.System3, but flow resistances have been added to have the same configuration as Annex60.Fluid.FMI.ExportContainers.Examples.FMUs.HVACZones. Having the same configuration is needed for the validation test Annex60.Fluid.FMI.ExportContainers.Validation.RoomHVAC.

The example extends from Annex60.Fluid.FMI.ExportContainers.HVACZone which provides the input and output signals that are needed to interface the acausal HVAC system model with causal connectors of FMI. The instance hvacAda is the HVAC adapter that contains on the left a fluid port, and on the right signal ports which are then used to connect at the top-level of the model to signal ports which are exposed at the FMU interface.

Extends from Annex60.Fluid.FMI.ExportContainers.HVACZone (Partial block to export an HVAC system that has no radiative component and that serves multiple zones as an FMU).

Annex60.Fluid.FMI.ExportContainers.Examples.FMUs.HVACZones

Declaration of an FMU that exports a simple convective only HVAC system for two zones

Annex60.Fluid.FMI.ExportContainers.Examples.FMUs.HVACZones

Information

This example demonstrates how to export a model of an HVAC system that only provides convective cooling to two thermal zones. The example is similar to Annex60.Fluid.FMI.ExportContainers.Examples.FMUs.HVACZone except that is serves two thermal zones rather than one.

The example extends from Annex60.Fluid.FMI.ExportContainers.HVACZones which provides the input and output signals that are needed to interface the acausal HVAC system model with causal connectors of FMI. The instance hvacAda is the HVAC adapter that contains on the left a fluid port, and on the right signal ports which are then used to connect at the top-level of the model to signal ports which are exposed at the FMU interface.

Annex60.Fluid.FMI.ExportContainers.Examples.FMUs.TwoPortPassThrough

Information

This example demonstrates how to export an FMU that simply passes all its inputs to its outputs. Such an FMU could for example be used in a block diagram as a place-holder for another FMU that provides an actual implementation of a component.

Extends from Annex60.Fluid.FMI.ExportContainers.PartialTwoPort (Partial block to be used as a container to export a thermofluid flow model with two ports).

Parameters

Type	Name	Default	Description
replaceable package Medium		PartialMedium	Medium in the component
Boolean	use_p_in	true	= true to use a pressure from connector, false to output Medium.p_default
Assumptions
Boolean	allowFlowReversal	true	= true to allow flow reversal, false restricts to design direction (inlet -> outlet)

Connectors

Type	Name	Description
replaceable package Medium		Medium in the component
Inlet	inlet	Fluid inlet
Outlet	outlet	Fluid outlet
