    Abstract: 研究期間:10108~10207;Most ventilation models do not consider the influences of furniture or internal obstacles on the building ventilation. Therefore, it is possible to over-estimate the ventilation rate when there are large obstacles in the path of airflow. This study plans to use a resistance model to calculate the ventilation rate of wind-driven cross ventilation with obstacles in the building. The ventilation rate of a model building will be measured by the tracer gas technique in a series of wind tunnel experiments. The effects of obstacle size, position and external wind speed on the ventilation rate will be systemically investigated. The experimental results will be analyzed to determine the flow resistance caused by the obstacles. The resistance model could be used by the architects to evaluate the ventilation rate and thermal comfort of buildings with internal obstacles.
