【英文篇名】 Building environment design simulation software DeST(8): combined simulation of natural and mechanical ventilation 【作者中文名】 张野; 章宇峰; 宋芳婷; 燕达; 江亿; 【作者英文名】 By Zhang Ye★; Zhang Yufeng; Song Fangting; Ya Da and Jiang Yi; 【作者单位】 清华大学; 【文献出处】 暖通空调, Hv 机械通风; 通风网络模型; 静压; 【英文关键词】 natural ventilation; mechanical ventilation; airflow network model; static pressure; 【摘要】 建筑通风对建筑环境的影响是直接而迅速的,因此对建筑热环境的模拟必须解决建筑通风的模拟问题。建筑的通风包括自然通风和机械通风,二者本质相同并且经常是同时发生的,计算时应该一起考虑,而不是分离开来。详细介绍了建筑热环境模拟软件DeST中根据多区域网络模型和管道流体网络模型发展出来的建筑通风的统一的网络模型,介绍其求解方法,并给出了建筑中常见的通风支路阻力模型,实现了建筑热环境和自然通风真正的耦合模拟。通过介绍几个利用通风模拟来分析解决设计中问题的实例,指出了建筑通风模拟的应用范围和实际意义。 【英文摘要】 It is very important to understand the building ventilation conditions, because ventilation and infiltration affect building environment directly and instantly. Ventilation in buildings includes natural ventilation and mechanical ventilation. They are essentially the same and often occur at the same time, so need to be considered together instead of separately. Explicates the uniform network model and the solving method in the building simulation tool-DeST, which is developed from the multizone airflow netw...
