两个个性化的表现。在全尺寸测试室中，在呼吸区提供空气的通风系统与地板下通风一起进行了测试，产生了两种不同的气流模式。两个呼吸暖和的假人被用来模拟乘员。在不同的个性化和地板下气流速度组合下，对与呼出的空气和地板材料排放相关的污染物的分布进行了评估。与单独的地板下通风相比，个性化的地板下通风为坐着的人提供了良好的保护，使其免受任何污染，同时房间内呼出的空气污染浓度增加。这两种类型的个性化通风效果不同。随后对空气传播感染风险的分析表明，个性化通风可能成为传统感染控制方法的补充。
The performance of two personalized. ventilation systems supplying air at the breathing zone was tested in conjunction with underfloor ventilation generating two different airflow patterns in a full-scale test room. Two breathing thermal manikins were used to simulate occupants. The distribution of pollutants associated with exhaled air and floor material emissions was evaluated at various combinations of personalized and underfloor airflow rates. Compared to underfloor ventilation alone, personalized and underfloor ventilation provided excellent protection Of seated occupants from any pollution, while the concentration of exhaled air pollution increased in the room. The two types of personalized ventilation performed differently. Subsequent analyses of airborne infection transmission risk indicated that personalized ventilation could become a supplement to traditional methods of infection control.
