摘要:
针对层式通风这一新型通风方式,在考虑外窗得热的条件下,通过采用Navier-Stokes方程与RNG的k-ε涡粘性湍流模型对空间气流的三维温度场、速度场、污染物CO2浓度场模拟,计算PPV及PPD指数,并且与相同情况下的置换通风方式进行对比.分析结果表明,在换气次数相同条件下,层式通风方式较置换通风方式能使呼吸区获得更好的IAQ与人体热舒适度.
Abstract:
In this present paper,the Reynolds-averaged Navier-Stokes equations and the RNG k-ε turbulence model are used to predict three-dimensional temperature field,velocity field,pollutant CO2 concentration distribution in considering the exterior windows and interior heat radiation conditions imposed by thermal buoyancy effects.It also has computed PPV and PPD to evaluate human thermal comfort.At the same time,its performance is compared with displacement ventilation in the same situation.The result shows that,with the stratum ventilation,occupancy can have favorable IAQ and thermal comfort in the breathing zone.
