摘要
为获得办公建筑内合理的通风模式,以兰州地区某办公室为研究对象,在考虑围护结构热惰性情况下,采用AIRPAK 3.0软件对不同送风速度下的置换通风和层式通风的流场、温度场、CO_2体积分数、PMV及空气龄等进行了对比分析.结果表明:层式通风具有无吹风感、温度更适宜、空气品质更好、CO_2体积分数更低的特点,对办公室内空气品质的调节优于置换送风,更易于提供健康、舒适的室内环境,在改善室内空气品质与热舒适性方面更具优势.
In order to obtain a reasonable ventilation mode in the office of Lanzhou,the software AIRPAK 3.0 was adopted to numerically analyze the flow field,temperature field,CO2 concentration,PMV and mean age of the air under different displacement ventilation and stratum ventilation with different air supply velocity when the building enclosure thermal inertia was taken into consideration.The results indicate that the stratum ventilation mode has some advantages such as draft-free sensation,more comfortable temperature,better air quality and lower CO2 concentration.The stratum ventilation is better than the displacement ventilation on air conditioning in office and it is easier to create a healthy and comfortable indoor environment.The stratum ventilation has more advantages in the improvement of indoor air quality and thermal comfort.
