Summary
Theoretical models estimate airflow and air temperature for a wall solar chimney in four modes: cooling with outdoor air, warming outdoor air via the cavity or via the room, and sealed recirculating heating, with a coefficient capturing room layout. Cavity-route heating moves the most air at the lowest temperature, the room route does the reverse, and sealed heating lies between, suiting cool weather, cold weather and intermittently occupied rooms respectively.
