Abstract

In airtight houses, it is important to control the ventilation airflow of each room in order to ensure good indoor air quality. Therefore, the mechanical ventilation equipment should be designed carefully, giving due consideration to the ventilation efficiency in rooms. This paper describes the ventilation efficiency of a three‐zone scale model with the experiment. The step‐down method is applied to clarify the age of air and other indexes of ventilation efficiency. The effects of ventilation airflow volume with no recirculation and of the recirculated airflow volume on ventilation efficiency are investigated.
