摘　　要：主要依靠自然通风的农村住宅厨房冬季空气污染较严重,燃料燃烧、炊事产生的的CO_(2)对人体健康造成较大危害,改善农村住宅厨房空气质量符合国家乡村振兴的时代要求。运用实测与模拟、数值计算与线性预测的方法分析内蒙古农村住宅厨房冬季通风组织方式与呼吸带CO_(2)分布特性。结果表明:1)农村住宅厨房最优通风组织序列是进深开间比值为1.5:1,外窗洞紧邻炉灶布置,该序列呼吸带区间水平截面的CO_(2)体积分数平均值之和最低为0.007286,CO_(2)体积分数小于2000ppm占比最高为26.04%;2)确定呼吸带区间水平截面CO_(2)体积分数平均值与厨房进深与开间尺寸的比值、外窗洞距炉灶台位置定量关系。文中研究为农村营造健康的生活环境相关研究提供新维度、新方法和新思路。Rural residential kitchens that mainly rely on natural ventilation have serious air pollution in winter.The CO_(2) produced by fuel burning and cooking can cause great harm to human health.Improving the air quality of rural residential kitchens is in line with the requirements of national rural revitalization.In the papper,the mode of ventilation organization and CO_(2) distribution characteristics of rural residential kitchens in Inner Mongolia were analyzed by means of measurement and simulation,numerical calculation and linear prediction.The results show that:1)The optimal ventilation tissue sequence for rural residential kitchen is that the ratio of lenth to width is 1.5:1,and the outer window hole is adjacent to the stove.Therefore,the least sum of the average CO_(2) volume fraction at the horizontal section is 0.007286,and the CO_(2) volume fraction less than 2000ppm is 26.04%.2)This study determines the quantitative relationship between the average CO_(2) volume fraction at the horizontal section of each respiratory belt,the shape of the kitchen,and the position of the outer window hole from the stove table,which provides new dimensions,new methods and new ideas for creating a healthy living environment in rural areas.
