Possible to implement a recirculating ventilation system for grain silos in Ironbug

I aim to model a closed-loop ventilation system for flat grain storage in Ironbug, for subsequent energy analysis with Honeybee.

System Principle:
Internal Circulation Technology extracts low-temperature air from the central zone of the grain mass and delivers it to the top of the storage structure via thermally insulated ducts, achieving uniform temperature distribution throughout the grain bulk. Critically, this process operates as a self-contained system with zero air exchange with the external environment.

Is it feasible to implement this in Ironbug?Can Air Loops be adapted for this purpose?Are there alternative approaches?

Would really appreciate your insights on this. Thanks in advance!
