| Abstract: | It's difficult to apply the age of air and ventilation effectiveness to evaluating the space with natural ventilation and cross ventilation, because the property of indoor environment changes under the influence of external condition. New index which expresses the unevenness in space for natural ventilation and cross ventilation is examined from movement and diffusion of tracer gas, in consideration of time scale of airflow field. And 2-zone model is examined as the macro model in consideration of unevenness. 1. Volume index is derived from concentration at exhaust to gas input at supply. And it is confirmed the index expresses the unevenness in space. 2. It is confirmed to able to grasp the overview of velocity distribution from the volume index. 3. 2-zone model based on the volume index is presented. And correspondence to the transient analysis is considered. 4. The identification method of the interzonal airflow rate is examined. |
