Measurement data and analysis of air distribution in one gymnasium is presented in which the airflow is isothermal. The region considered includes both workaround and non- workaround., which can describe the airflow pattern of this gymnasium correctly.
Based on measured data, the airflow pattern of the HVAC system is analyzed. And the characteristic of airflow pattern in this kind of large space is summed up. Then some conclusions are drawn as a guide for airflow pattern designing in large space of the similar type.
