modelThermalZoneHVACNoExhaust
Example of a thermal zone and an HVAC system both exposed using the FMI adaptor
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This example demonstrates how to use the adaptors Buildings.Fluid.FMI.Adaptors.HVAC and Buildings.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.
