【英文篇名】 Comparative study on several common ventilation performances for bathroom by means of numerical simulation 【作者中文名】 胡良杰; 陈康民; 叶舟; 【作者英文名】 Hu Liangjie Chen Kangmin Ye Zhou（College of power; University of Shanghai for science and technology; Shanghai 200093 china）; 【作者单位】 上海理工大学动力学院; 上海理工大学动力学院 上海; 【文献出处】 制冷与空调(四川), Refrigeration nbsp; 期刊荣誉：ASPT来源刊 CJFD收录刊 【关键词】 浴厕; 水蒸汽; 通风方式; 数值模拟; 【英文关键词】 bathroom; vapor; ventilation performance; numerical simulation; 【摘要】 针对我国住宅浴厕常用的几种通风方式,运用计算流体力学(CFD)方法,分别对它们的通风气流组织形式进行了数值模拟分析,并对它们排除水蒸汽的能力进行了对比,认为浴厕排除水蒸汽必须采用机械通风,得出排风口位于房间顶部的通风方式要好于排风口位于侧墙或窗上的通风方式,并建议在进行建筑设计时,就应该考虑浴厕内的通风方式,布置好门、窗和排风扇的位置,提供住宅浴厕相对理想的通风方案,以便获得较好的通风效果,有效的排除浴厕内的水蒸汽,提高沐浴时的空气质量。对不同布局浴厕通风效果的比较,也为浴厕布局设计提供了指导,为我国住宅浴厕通风设计提供了参考,为住宅建筑设计提供了依据。 【英文摘要】 In view of several common ventilation performances in residential bathroom in our country,with the help of computational fluid mechanics(CFD) method,the simulation analysis on their characteristics of ventilation airflow was made,and the capacities of eliminating vapor in outlets were contrasted.The mechanical ventilation must be adopted in bathroom in order to eliminate water vapor,and the extraction fan located in the top of the room was better than the extraction fan located in the wall or window.When th...
