摘要: Abstract Airflow and thermal stratification solutions in a single-zone building with buoyancy-driven ventilation are derived. Two new ‘empty air-filling box’ models developed, it is shown that the fully-mixed model overpredicts clean zone height airflow rate, while ‘emptying water-filling underpredicts two parameters. It also found fully mixed predicts much lower neutral level for than predicted by considering stratification.
