摘要
提出一种在厨房吊顶设置补风口的方案,解决室内热舒适与空气污染之间的矛盾。对开窗通风与吊顶补风工况进行现场试验,监测室内温度与CO_(2)体积浓度变化;应用Fluent软件建模分析开窗通风与吊顶补风两种方案的温度与CO_(2)体积浓度分布特征,进而对开口位置模拟优化。结果表明,开启补风口后室内热环境有所改善,呼吸区温度相比开窗时高15.8℃,室内CO_(2)平均体积浓度仅比开窗时高0.0027%;补风口设置在厨房中后部时,效果更佳。吊顶补风方案能够兼顾室内温度与空气品质,具有一定的新风预热效果,易操作、成本低,更易于居民接受。
By installing air vents on the kitchen ceiling,it is possible to alleviate the conflict between indoor thermal comfort and air pollution.This study aims to identify the optimal placement of air vents in cold regions.On-site tests will be conducted to evaluate window ventilation and ceiling air replenishment,monitoring indoor temperature and CO_(2) levels.Utilizing Fluent software,a model will be developed and analyzed.This model will be validated against experimental data,leading to an optimization simulation of vent placement.Results show that indoor conditions improve significantly with air vents.Compared to window ventilation,the temperature in breathing areas increases by 15.8 degrees Celsius,with indoor CO_(2) concentrations only 0.0027%higher.Placing the air supply outlet at the back of the kitchen enhances ventilation.This ceiling ventilation scheme effectively balances indoor temperature comfort and kitchen air quality,offering insights for optimizing airflow in residential kitchens and creating a comfortable environment in cold regions.
