Example of a thermal zone and an HVAC system both exposed using the FMI adaptor

Annex60.Fluid.FMI.Adaptors.Examples.ThermalZoneHVACNoExhaust

Information

This example demonstrates how to use the adaptors Annex60.Fluid.FMI.Adaptors.HVAC and Annex60.Fluid.FMI.Adaptors.ThermalZone

On the left hand side is an HVAC system with supply and return air stream. These are all connected to the adaptor. On the right of the adaptor is a simple room model, approximated by a volume with first order dynamics and heat loss to the ambient.

Note that the there is zero net air flow into and out of the volume vol because the adaptor hvacAda conserves mass. Hence, any infiltration or exfiltration needs to be connected to the adaptor hvacAda, rather than the volume vol.

Annex60.Fluid.FMI.Adaptors.Examples.ThermalZoneHVACWithExhaust

Information

This example demonstrates how to use the adaptors Annex60.Fluid.FMI.Adaptors.HVAC and Annex60.Fluid.FMI.Adaptors.ThermalZone

It is identical to Annex60.Fluid.FMI.Adaptors.Examples.ThermalZoneHVACNoExhaust except that it adds a forced exhaust air stream.

Extends from Annex60.Fluid.FMI.Adaptors.Examples.ThermalZoneHVACNoExhaust (Example of a thermal zone and an HVAC system both exposed using the FMI adaptor).
