Summary
Uses a steady-state energy-balance model, solved by matrix inversion in MATLAB, to assess how well a solar chimney ventilates underground spaces under Korean climate conditions. Airflow depends on the temperature rise in the air channel, which is set by solar radiation, stack height and gap width; seasonal ventilation rates vary by less than 25%, so the system works all year round.
