【摘要】：如何实现社会的的可持续发展，是我国当前面临的主要问题。未来二十年，我国的城镇化进程将持续快速发展。然而长久以来，依赖规模效益和短期效益的粗放式发展模式已经使得全社会对人口、资源、环境的压力日趋不堪重负。因此，作为能源消耗的大项，建筑行业必须向低能耗、低污染的方向转型。空调能耗在建筑能耗中占很大比例，利用自然通风技术降低建筑能耗对整个建筑乃至社会的可持续发展都有重要意义。当前，建筑节能技术的发展经过宏观层面的概念设计及试错阶段，已逐步开始入实践积累和量化分析的微观层面。本文所探讨的是寒冷地区建筑被动节能自然通风的策略和数值分析。第一章是绪论部分，陈述了文章的选题背景和选题意义，，总结了国内外相关研究内容和成果，明确了研究的方向和研究方法。本文的第二章是概念解析部分，该部分首先解释了本文选题中“寒冷地区被动节自然通风能策略”的含义并明确了其研究范畴。其次，从不同角度对当前常见的被动节能自然通风措施进行了归纳总结，为更进一步的研究打下基础。再次，探讨了被动节能自然通风的作用时段和室内热舒适的基本要求，这些内容将成为试验环节中不可缺少的前提和参考。第三章是本文的重点，在定性总结的基础上，利用CFD流体力学模拟软件对不同策略在特定工况下的效果进行了量化分析，从微观的层面探讨了不同通风策略在寒冷地区环境下的运用。通过计算机模拟分析，首先对风压作用下的建筑群体布局、功能设置、捕风构件（以捕风井为例）作用进行了量化分析。其次，对热压作用下的通高空间，太阳能烟囱进行了分析模拟。最后研究的是热压与风压共同作用下的复杂工况。本文第四章则列举了三个寒冷地区绿色建筑建筑实例，对其通风策略进行了探讨。
[Abstract]:How to realize the sustainable development of society, is the main problem facing our country. The next twenty years, China's urbanization process will be sustained and rapid development. However, rely on economies of scale and short-term benefits of the extensive mode of development has made the whole society of population, resources and environmental pressures become increasingly overwhelmed. Therefore, as the large energy consumption, the construction industry must transition to low energy consumption, low pollution. Air conditioning energy consumption accounted for a large proportion in building energy consumption, has important significance to sustainable development of the whole society construction and even the use of natural ventilation technology to reduce building energy consumption. At present, the construction of energy-efficient technology development after the conceptual design stage of macro and trial and error the level of analysis has gradually started to practice accumulation and quantify the micro level. This paper is to explore the cold area building natural ventilation strategy and passive energy saving Numerical analysis.
The first chapter is the introduction part, the article stated the background and significance of the topic, summarizes the related research contents and achievements, clarifies the direction and method of the research. The second chapter is the concept analysis part, the first part explains the topic of "passive energy saving strategy in cold area" the meaning of natural ventilation and clarify the scope of the study. Secondly, summarizes the passive energy saving natural ventilation measures from different angles to the common, for further research to lay the foundation. Thirdly, to investigate the effect of natural ventilation time of passive energy-saving and basic requirements of indoor thermal comfort, which will become the indispensable premise and reference test link the third chapter is the focus of this paper, based on qualitative summary, simulation software of the effect of different strategies in specific conditions for using CFD fluid mechanics Analysis of the use of different ventilation strategies in the environment of cold region from the micro level. Through computer simulation, first set the function of the pressure under the action of the building layout, and the wind component (as well as an example of wind) are quantitatively analyzed. Secondly, the hot pressing under high space. The solar chimney is analyzed. Finally, simulation research is complicated interaction of hot pressing and pressure. The fourth chapter enumerates three examples of green building construction in cold areas, the ventilation strategies were discussed.
