【摘要】：如何實(shí)現(xiàn)社會(huì)的的可持續(xù)發(fā)展，是我國當(dāng)前面臨的主要問題。未來二十年，我國的城鎮(zhèn)化進(jìn)程將持續(xù)快速發(fā)展。然而長久以來，依賴規(guī)模效益和短期效益的粗放式發(fā)展模式已經(jīng)使得全社會(huì)對人口、資源、環(huán)境的壓力日趨不堪重負(fù)。因此，作為能源消耗的大項(xiàng)，建筑行業(yè)必須向低能耗、低污染的方向轉(zhuǎn)型�？照{(diào)能耗在建筑能耗中占很大比例，利用自然通風(fēng)技術(shù)降低建筑能耗對整個(gè)建筑乃至社會(huì)的可持續(xù)發(fā)展都有重要意義。當(dāng)前，建筑節(jié)能技術(shù)的發(fā)展經(jīng)過宏觀層面的概念設(shè)計(jì)及試錯(cuò)階段，已逐步開始入實(shí)踐積累和量化分析的微觀層面。本文所探討的是寒冷地區(qū)建筑被動(dòng)節(jié)能自然通風(fēng)的策略和數(shù)值分析。 第一章是緒論部分，陳述了文章的選題背景和選題意義，，總結(jié)了國內(nèi)外相關(guān)研究內(nèi)容和成果，明確了研究的方向和研究方法。本文的第二章是概念解析部分，該部分首先解釋了本文選題中“寒冷地區(qū)被動(dòng)節(jié)自然通風(fēng)能策略”的含義并明確了其研究范疇。其次，從不同角度對當(dāng)前常見的被動(dòng)節(jié)能自然通風(fēng)措施進(jìn)行了歸納總結(jié)，為更進(jìn)一步的研究打下基礎(chǔ)。再次，探討了被動(dòng)節(jié)能自然通風(fēng)的作用時(shí)段和室內(nèi)熱舒適的基本要求，這些內(nèi)容將成為試驗(yàn)環(huán)節(jié)中不可缺少的前提和參考。第三章是本文的重點(diǎn)，在定性總結(jié)的基礎(chǔ)上，利用CFD流體力學(xué)模擬軟件對不同策略在特定工況下的效果進(jìn)行了量化分析，從微觀的層面探討了不同通風(fēng)策略在寒冷地區(qū)環(huán)境下的運(yùn)用。通過計(jì)算機(jī)模擬分析，首先對風(fēng)壓作用下的建筑群體布局、功能設(shè)置、捕風(fēng)構(gòu)件（以捕風(fēng)井為例）作用進(jìn)行了量化分析。其次，對熱壓作用下的通高空間，太陽能煙囪進(jìn)行了分析模擬。最后研究的是熱壓與風(fēng)壓共同作用下的復(fù)雜工況。本文第四章則列舉了三個(gè)寒冷地區(qū)綠色建筑建筑實(shí)例，對其通風(fēng)策略進(jìn)行了探討。
[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.
