摘要
结合人体呼吸模型建立了室内人员所获得有效新风量的计算模型,并对不同通风模式、新风量大小和污染源强度影响下的有效新风量的特征性做出分析。研究结果表明,混合通风条件下的人员有效新风量要低于置换通风条件下的对应结果;同时,入室新风量的增大可以使人员有效新风量提高,但提高的程度取决于通风模式;此外,污染源强度的变化对人员有效新风量的影响较小。
Model for calculating person effective outdoor airflow in building room was obtained based on human breathe model.Characteristics of the person effective outdoor airflow were analyzed for different ventilation type,outdoor airflow of ventilation and pollution sources emission intensity.The results show that the person effective outdoor airflow of mixing ventilation is less than that of displacement ventilation.Furthermore,rise of outdoor airflow may make the person effective outdoor airflow increase,but its degree of increase depends on ventilation type.In addition,the pollution sources emission intensity has small influence on the person effective outdoor airflow.
