目的 分析苏州市集中空调通风系统可吸入颗粒物(PM10)的污染现状,同时研究大气污染对其影响。方法 2017—2018年检测苏州市70家公共场所集中空调通风系统PM10浓度。查询、记录苏州地区当日大气中主要污染物浓度。结果 苏州市公共场所集中空调通风系统PM10浓度总合格率为62.86%(44/70),采样风口合格率为82.43%(319/387)。采用中级新风过滤装置的集中空调通风系统PM10浓度送风口合格率(89.01%,162/182)高于采用初级新风过滤装置的集中空调通风系统PM10浓度合格率(76.59%,157/205),差异有统计学意义(χ2=10.28,P<0.01);中级新风过滤装置系统PM10平均浓度低于初级新风过滤装置系统PM10平均浓度,差异有统计学意义(t=2.41,P<0.05)。集中空调空调系统PM10浓度与该日大气中PM10浓度呈正相关关系(rs=0.450,P<0.01)。结论 2017—2018年苏州市37.14%(26/70)的使用集中空调通风系统的公共场所中送风PM10浓度不合格,并且会受到室外大气污染状况的影响。大型公共场所在进行集中空调通风系统设计安装时,要考虑室外大气污染状况,对空气过滤装置提出相应的要求。

Objectives To analyze the pollution status of inhalable particles (PM10)in central air conditioning and ventilation system in Suzhou,and to study its correlation with air pollution. Methods The study determined concentrations of PM10 in the central air conditioning and ventilation system of 70 public places in Suzhou, and searched concentrations of the major atmospheric pollutants in Suzhou on the day. Results The total qualified rate of PM10 concentration in the central air conditioning and ventilation system of public places in Suzhou was 62.86% (44/70) and the qualified rate of sampling air outlet was 82.43%(319/387). The qualified rate of air supply outlet of PM10 concentration of the central air conditioning and ventilation systems with the intermediate fresh air filter (89.01%, 162/182) was higher than that of the systems with the primary fresh air filter (76.59%, 157/205), and a statistically significant difference was observed(χ2=10.28, P<0.01). The average concentration of PM10 in intermediate fresh air filter system was lower than that in primary fresh air filter system, and a statistically significant difference was observed (t=2.41,P<0.05).There was a positive correlation between concentration of PM10 in air conditioning system and atmospheric PM10 concentration on the day (rs=0.450, P<0.01). Conclusions In 2017—2018, 37.14%(26/70) of public places using central air conditioning and ventilation system in Suzhou was unqualified in PM10 concentration of air supply, which was correlated to outdoor air pollution. The outdoor air pollution should be considered in the design and installation of central air conditioning and ventilation system in large public places and the corresponding requirements for air filter devices should be put forward.
