摘要
不同气候区的室外PM2.5污染情况,不同年代、不同层数的住宅外门窗气密性等对室内空气净化器的配置选型有着重要影响。本文结合中国工程建设标准化协会标准T/CECS 586-2019《建筑室内细颗粒物(PM2.5)污染控制技术规程》,选取"不保证5天"的PM2.5室外计算浓度、现行值I级的PM2.5室内计算浓度作为空气净化器设计选型的计算参数。同时,结合不同年代、不同层数住宅外门窗气密性等级,利用建筑室内PM2.5污染控制设计计算方法,给出不同地区住宅室内空气净化器的配置选型系数表,为住户配置室内空气净化器提供一定参考。
The outdoor PM2.5 pollution in different climatic zones,and airtightness of exterior doors and windows in building of different ages and floors,all have important impacts on the selection of indoor air cleaners.Based on the Standard of China Association for Engineering Construction Standardization T/CECS 586-2019 "Technical Specification for Pollution Control of Fine Particulate Matter( PM2.5) in Building",this paper selected the calculated concentration of outdoor PM2.5 with "not guaranteed for 5 days"and the current value I for calculated concentration of indoor PM2.5 as the setting parameters for the design and selection of indoor air cleaners.Moreover,combining the airtightness of exterior doors and windows in buildings of different ages and different floors,this paper designed the calculation approach using indoor PM2.5 pollution control and proposed a table of selection factors for the configurations of residential indoor air cleaners in different regions,providing references for the selection of indoor air cleaners.
