本文提出了一个实验模拟的污染物扩散的隔离室与不同的负压差和通风量。一个假设的污染物（六氟化硫，SF6）是从一个病人躺在床上的模拟隔离室。定量评价了通风量12和24 h（-1）以及压差-2.5、-5.0、-8.0和-15.0 Pa对室内通风效果的影响。研究中引入了当地空气质量指数和医护人员暴露指数来评价隔离室的通风效率。根据实验结果，隔离室的通风效率在-15.0 Pa/24 h（-1）时最高，其次分别为-15.0 Pa/12 h（-1）、-8.0 Pa/24 h（-1）、-5.0 Pa/24 h（-1）、-2.5 Pa/24 h（-1）、-8.0 Pa/12 h（-1），-5.0 Pa/12 h（-1）和-2.5 Pa/12 h（-1）。）(C)2008爱思唯尔有限公司保留所有权利。
This paper presents an experimental modeling of contaminant dispersion in a mock-up isolation room with different negative pressure differentials and ventilation rates. A hypothetical contaminant (sulfur hexafluoride, SF6,) is emitted from a patient lying on a bed in the mock-up isolation room. The impacts of ventilation rates 12 and 24 h(-1) and pressure differentials -2.5, -5.0, -8.0, and -15.0 Pa on the ventilation effectiveness in the room are evaluated quantitatively. A local air quality index and an exposure index for healthcare workers are introduced in the research to evaluate the ventilation efficiency of the isolation room. Based on the results of our experiment, the ventilation efficiency of the isolation room ranks the highest at -15.0 Pa/24 h(-1), followed, respectively, by - 15.0 Pa/12 h(-1), -8.0 Pa/24 h(-1), -5.0 Pa/24 h(-1), -2.5 Pa/24 h(-1), -8.0 Pa/12 h(-1), -5.0 Pa/12 h(-1), and -2.5 Pa/12 h(-1).)
