摘　　要：高校宿舍的室内空气品质与学生的舒适健康和工作效率关系密切,当前我国高校宿舍空气品质的改善主要依靠自然通风。通过长期监测武汉某高校一宿舍室内的PM_(2.5)和CO_(2)浓度,分析了不同自然通风策略和室内人员对室内空气品质的影响。结果表明,室内PM_(2.5)浓度主要与室外PM_(2.5)浓度和自然通风策略有关,不通风时室内PM_(2.5)浓度仅为室外的70%,加强自然通风会使室内外PM_(2.5)浓度不断接近。室内CO_(2)浓度与自然通风策略和人员数量均有密切联系,较低的门窗开度即可有效的降低夜间室内的CO_(2)浓度。Indoor air quality(IAQ)of college dormitories is closely related to comfort,health and work efficiency of students.The improvement of IAQ mainly depends on natural ventilation.In order to analyze the impact of different natural ventilation strategies and personnel on IAQ,we monitored PM_(2.5)and CO_(2)concentration in a college dormitory in Wuhan during a long period.The result shows that the indoor PM_(2.5)concentration is mainly related to the outdoor PM_(2.5)concentration and natural ventilation strategy.The indoor PM_(2.5)concentration is only 70%of that of the outdoor without ventilation,and will be continuously close to that of the outdoor with the increase of ventilation to outside.Indoor CO_(2)concentration is closely related to the natural ventilation strategy and the amount of personnel.A narrow opening of the door or window can effectively reduce indoor CO_(2)concentration at night.
