摘要
采用数值模拟法研究冬季雾霾天供暖时,散热器位置对室内气流组织和颗粒物沉积分布的影响。结果表明,散热器置于窗户下方时,室内粒子浓度以及固体壁面处的粒子沉积量均低于其他位置。当由于条件限制,散热器不能置于窗户下方时,应避免摆放在靠外墙却不在窗户下方的位置。
Numerical simulations were carried out to analyze the effect of radiator position on the indoor airflow pattern and the distribution of particle deposition when room heating devices were operated in winter hazy days.The result shows that when the radiator is placed under the window,indoor particle concentration in the room and the amount of particles deposited on the solid walls are lower than those in other locations.When the radiator cannot be located under the window due to the restriction,the place that near the exterior wall but not under the window should be avoided.
