摘要

本研究使用21个低成本PM2.5传感器（在17个室内和2个室外地点）评估了18个月内室外空气质量差对室内空气质量的影响，重点关注逆温、灰尘和野火烟雾事件。除了室外空气质量对室内空气质量的影响外，本研究还评估了不同供暖、通风和空调（HVAC）系统对商业建筑室外PM2.5渗透的影响。野火烟雾事件对室内空气质量的影响最大。逆温、沙尘和野火烟雾事件在所有地点的平均入渗因子分别为0.07、0.10和0.37。此外，与其他系统相比，配备空气侧省煤器的HVAC系统在没有污染事件的情况下显示出更高的PM2.5渗透系数。

Understanding the effect of outdoor pollution episodes and HVAC type on indoor air quality

This study evaluated the impact of poor outdoor air quality on indoor air quality over 18 months using 21 low-cost PM_2.5 sensors (at 17 indoor and two outdoor locations) with a focus on inversion, dust, and wildfire smoke events. In addition to the impact of outdoor air quality on indoor air quality, this study evaluated how different heating, ventilation, and air conditioning (HVAC) systems affect the infiltration of outdoor PM_2.5 in commercial buildings. Wildfire smoke events had the largest impact on indoor air quality. Infiltration factors averaged over all locations for inversion, dust, and wildfire smoke events were 0.07, 0.10, and 0.37, respectively. Additionally, HVAC systems equipped with an air-side economizer showed higher PM_2.5 infiltration factors compared to other systems regardless of pollution event.
