Airborne fine particulate matter (PM2.5) is an important factor affecting indoor air quality and is significantly related to human health. A lot of research has been done on PM2.5 pollution control in buildings, but there is lack of systematic indoor PM2.5 pollution control for engineering applications. In this study, first, we propose an outdoor calculated concentration of PM2.5 in 74 cities, in China, using the "not guaranteed for five days" method, which is based on outdoor PM2.5 concentration monitoring data from 2016 to 2018. Then, different levels of indoor calculated concentrations of PM2.5 (25 μg/m, 35 μg/m, and 75 μg/m) are put forward. Secondly, methods for selecting air purification equipment in centralized, semi-centralized, and decentralized air conditioning systems are proposed. Finally, PM2.5 pollution control measures and system energy-saving operation strategies in buildings are put forward. This study stipulates the calculation of PM2.5 concentration, unifies design methods, proposes control measures, and standardizes operations management. The aim of this study is to provide technical guidance for engineering design, construction and operation, and therefore to reduce the risk of indoor diseases caused by exposure to PM2.5.
空气中的细颗粒物（PM2.5）是影响室内空气质量的重要因素，与人类健康密切相关。大量研究已经针对建筑物中的 PM2.5 污染控制展开，但缺乏针对工程应用的系统的室内 PM2.5 污染控制。在本研究中，首先，我们使用“不保证五天”方法，提出了中国 74 个城市的室外 PM2.5 计算浓度，该方法基于 2016 年至 2018 年的室外 PM2.5 浓度监测数据。然后，提出了不同水平的室内 PM2.5 计算浓度（25μg/m³、35μg/m³和 75μg/m³）。其次，提出了集中式、半集中式和分散式空调系统中空气净化设备的选择方法。最后，提出了建筑物中 PM2.5 污染控制措施和系统节能运行策略。本研究规定了 PM2.5 浓度的计算方法，统一了设计方法，提出了控制措施，并规范了运行管理。本研究旨在为工程设计、施工和运行提供技术指导，从而降低因接触 PM2.5 而导致的室内疾病风险。
