摘　　要：目的　了解密闭空调环境的空气质量。方法　选择使用同一中央空调系统的 9间密闭结构的办公场所 ,并用公共场所卫生标准检验方法测定其气温、气湿、CO2 、CO、甲醛、可吸入颗粒物(IP)、细菌总数 (BT)、溶血性链球菌 (HS) ;用大气离子浓度测量仪测定空气离子 ;用闪烁瓶氡测量仪测定放射性元素氡。结果　受调查办公场所中 ,室温平均为 2 3.1℃ ,相对湿度平均为 81.5 % ,风速平均为 0 .13m/s,CO2 浓度平均为 0 .0 4 8% ,CO浓度平均为 1.8mg/m3 ,甲醛浓度平均为 0 .0 5 2mg/m3 ,IP浓度平均为 0 .0 84mg/m3 ,BT平均为 12 7CFU/m3 ,HS未检出 ,负离子的平均浓度为 2 0 3个 /cm3 ,氡的平均水平为 4 .9Bq/m3 。结论 :密闭中央空调环境的微小气候恒定 ,比较舒适。CO2 、CO、甲醛、IP以及BT、HS含量、氡等主要污染物均未超出国家有关卫生标准的限定值。但空调环境负离子浓度比室外低。Objective To determine and evaluate the air quality in the enclosed air-condition environment.Methods A total number of 9 enclosed working places in a same air-condition system were sampled. Temperature and humidity, the concentrations of CO 2, CO, formaldehyde, IP ,BT and HS were detected by standard examination methods; Air negative-ion was detected by detection instrument; Radon concentration in air was measured by scintillation flask method.Results In these sampled places, the average room temperature was 23.1℃, the average relative humidity was 81.5% and the wind speed was 0.13 m/s. The average concentrations of CO 2, CO, formaldehyde, IP and BT were 0.048%, 1.8 mg/m 3, 0.052 mg/m 3, 0.084 mg/m 3 and 127 CFU/m 3 respectively, but HS was not detected. The average concentration of negative-ion was 203/cm 3, and the average concentration of Radon was 4.9 Bq/m 3. Conclusion The micro-climate in enclosed air-condition environment was stable and comfortable. The concentrations of main pollutants, CO 2, CO, formaldehyde, IP,BT,HS and radon, met the National Hygiene Standard. The concentration of negative-ion was lower than that of out-room.
