摘　　要：为控制室内PM10的质量浓度,基于质量平衡方程建立了室内可吸入颗粒数学模型并对其进行简化;推导出空调通风系统在开启、关闭两种时段下室内PM10浓度瞬时式。通过数值计算,分析了初始PM10浓度、室外PM10浓度、渗风量、新风比、过滤器效率等因素对室内PM10浓度变化的影响。计算结果表明:提高集中空调系统的各级过滤器效率,有助于改善室内颗粒物污染状况。Using simplified mathematical model of mass balance equation to control indoor PMIO concentra- tion, the instantaneous concentration of air conditioning system in rooms with and without ventilation is derived. Through numerical calculation, analysis the change tration,outdoor PMIO that enhancer of filter of indoor particle concentration when the initial PMIO concen- concentration, infiltration rate, fresh air ratio, filter efficiency are varied. The results show efficiency at various levels used in central air- conditioning systems is helpful for improving indoor particle contamination condition
