摘　　要：室内空气环境包括室内热湿环境和室内空气品质,而合理的通风方式是良好室内热湿环境和室内空气品质的根本保障。本文利用Air-pak软件建立了实验室的物理模型与数字模型,用数值模拟的方式分析夏季典型气候工况下同济大学文远楼外围护结构节能实验室内的空气质量及热工性能,并分别对转换通风,上送上出2种不同通风方式下的速度场、污染物浓度分布、进行模拟计算,并对模拟结果进行分析,得出结论:转换通风在速度场、热舒适性和改善室内空气品质方面都明显优于传统的上送上出通风方式。Indoor air environment includes indoor thermal environment and indoor air quality, and reasonable ventilation mode is the fundamental guarantee for a good indoor thermal environment and indoor air quality. This paper uses the Air-pak software to establish the laboratory physical model and numerical model, and makes numerical simulation analysis of air quality and thermal performance in energy saving laboratory of outer building envelope of Wenyuan Building at Tongji University under typical summer weather conditions and simulation calculation of velocity field and pollutant concentration distribution of two different modes of ventilation namely displacement ventilation and up-inlet and up-outlet ventilation. The simulation results are analyzed and such conclusion is reached that the displacement ventilation is obviously superior to the traditional up-inlet and up-outlet ventilation regarding velocity field, thermal comfort and indoor air quality improvement.
