PM2.5室外设计浓度是建筑物空调通风系统配置空气净化设备的重要依据。讨论了国内当前具有代表性的2种确定PM2.5室外设计浓度的推荐方案,介绍了日本公共建筑空调通风系统空气净化设备选型用室外悬浮颗粒物设计浓度的确定方法,对国内当前制订相关标准提出了一些建议。
PM2.5 outdoor design concentration is the building air conditioning and ventilation system configuration air purification equipment, an important basis. This paper discusses two representative schemes for determining the concentration of PM2.5 outdoor design in China, and introduces the method for determining the design concentration of outdoor suspended particulates for the selection of air purification equipment for air conditioning and ventilation systems in public buildings in Japan. Made some suggestions
