Top-down precooled natural ventilation

That paper shows how a top-down precooled natural ventilation can be an effective and energy efficient technique for providing thermal and ventilation comfort in a wide range of modern buildings during high summer or in warm climates, when used properly.For that study, the top-down precooled natural ventilation of an occupied open-plan space is equipped with a high-level vent and a low-level vent . A chiller unit is connected to the high-level vent to provide precooling. A quantitative model has been developed and tested with analogue laboratory experiments. The results are presented.
