烹饪过程中产生的污染物对居住者的健康有害。在我国夏热冬冷地区的传统住宅厨房中，安装抽油烟机是为了排出油烟等污染物。在典型的厨房中，空气通过防虫网供应。然而，这种送排风系统不能提供良好的厨房室内空气品质的气流组织。为解决这一问题，提出了缝式风幕送风与抽油烟机排风相结合的推拉式通风系统方案。采用数值模拟和现场试验相结合的方法，研究了不同通风方式下的风速、温度和污染物分布。在数值模拟过程中进行了正交试验。在L25（56）正交试验中，选取风幕速度（A）、风幕角度（B、C、D、E）和排风速度（F）为6个因素。比较25例患者呼吸区CO2平均浓度。结果表明，单独使用抽油烟机不能有效地将烹饪产生的油烟排出厨房。通过应用推拉式通风系统，可以在夏季场景期间降低空气温度，这可以改善乘员的热舒适性。同时，改善气流组织可以降低污染物浓度。各影响因素对污染物浓度分布影响的大小顺序为A>B>C>E>D>F。为降低厨房室内污染物浓度提供了科学依据。
Pollutants generated from cooking process are detrimental to occupant's health. For conventional residential kitchen in hot summer and cold winter region of China, range hood is installed to exhaust oil fume and other pollutants. In typical kitchen, air is supplied through the insect screen. However, this kind of air supply and exhaust system is not capable of providing air distribution for good indoor air quality in kitchen. In order to solve this problem, the combined scheme with air supply through slot air curtain and air exhaust through range hood is proposed, which is termed as the push-pull ventilation system. Both numerical simulation and field test were carried out to investigate the air velocity, temperature and pollutant distributions. Orthogonal study was performed during numerical simulation. Air curtain velocity (A), air curtain angle (B, C, D, E) and exhaust velocity (F) were chosen as six factors during the L25(56) orthogonal test. The average CO2concentration of the 25 cases in breathing region was compared. It is shown that by using the range hood alone, oil fume generated by cooking cannot be effectively exhausted out of the kitchen. With application of the push-pull ventilation system, the air temperature can be reduced during the summer scenario, which may improve occupant thermal comfort. Meanwhile, the pollutant concentration can be reduced with the improved air distribution. Moreover, the sequence for effect of influencing factors on the pollutant concentration distribution is A>B>C>E>D>F. This proposal provides a scientific support to reduce the indoor pollutant concentration in kitchen.
