摘　　要：通过对幼儿园生活单元建立物理数学模型,基于Airpak模拟分析了排风量、新风量、新风口位置以及室外风速对室内空气品质的影响。结果表明,门窗关闭的室内,仅设置排风并不能有效降低室内CO_(2)平均浓度;引入新风对降低室内CO_(2)平均浓度效果显著;新风口距离人员越近,并非越有利于降低室内CO_(2)平均浓度;过渡季节,开启门窗室内CO_(2)平均浓度水平明显降低。By establishing a physical mathematical model of the kindergarten living unit,the paper analyzes the influence of exhaust air volume,fresh air volume,location of fresh air inlet and outdoor wind speed on indoor air quality based on Airpak simulation.The results show that the average indoor CO_(2) concentration can not be effectively reduced by seting only exhaust air when doors and windows are closed;The introduction of fresh air has a significant effect on reducing the average indoor CO_(2) concentration;The closer the fresh air inlet is to the personnel,the less conducive it is to reduce the average indoor CO_(2) concentration;During the transition season,the average indoor CO_(2) concentration decreased significantly when doors and windows are open.

关 键 词：空气品质 室内CO_(2)平均浓度 新风
