【摘要】：節(jié)能減排是減輕環(huán)境污染、解決能源危機的重要途徑，建筑能耗占社會總能耗30%左右。隨著我國城鎮(zhèn)化水平的不斷提高，產業(yè)結構的調整，建筑能耗的比例將繼續(xù)提高。要實現(xiàn)節(jié)能65%的目標，則必須提高圍護結構保溫隔熱性能。目前我國的外墻保溫隔熱技術相比國外還存在一定的差距，因此有必要參照國外發(fā)展經驗，做好外墻保溫系統(tǒng)的熱橋阻斷、空氣隔斷等工作，這對于國內建筑節(jié)能事業(yè)的發(fā)展具有非常積極的意義。本文以一體化外墻保溫系統(tǒng)為研究對象，通過理論計算、CFD模擬、DeST建筑能耗分析以及實測數(shù)據(jù)等方法，分析空氣間層定型尺寸對一體化外墻保溫系統(tǒng)保溫隔熱性能的影響。 首先本文闡述了我國常用的外墻保溫系統(tǒng)安裝方法及特點，安裝過程中主要節(jié)點的處理方法，列舉了濕式與干式安裝方法的優(yōu)點和不足，并指出空氣間層的引入可以提高干式安裝方法的保溫性能。 第三章首先介紹了一體化外墻保溫系統(tǒng)典型構造，根據(jù)傳熱學傅立葉定律和格拉曉夫準則等基本原理對該系統(tǒng)進行傳熱理論分析；并將該系統(tǒng)簡化成物理模型，根據(jù)合肥地區(qū)氣候條件確定邊界條件，將上述問題簡化為二維穩(wěn)態(tài)傳熱溫度，進行CFD模擬。研究空氣間層定型尺寸對該系統(tǒng)傳熱性能的影響，確定工程應用的最優(yōu)安裝尺寸。 第四章根據(jù)上面最優(yōu)定型尺寸的計算，應用在示范工程百樂門尚澤國際寫字樓項目中，使用DeST建筑能耗分析軟件對示范工程全年8760h室內溫度進行模擬，對模擬結果進行數(shù)據(jù)分析，，根據(jù)前人在室內舒適度方面的研究，確定冬季供暖和夏季空調開啟時間，對夏熱冬冷地區(qū)建筑節(jié)能提出建議。 文章最后統(tǒng)計分析了實驗房采集的溫度和熱流密度數(shù)據(jù)，分析了近兩年實時測量的溫度分布情況，結合熱流密度采集的數(shù)據(jù)，計算出冬季12月、1月和夏季7月、8月的熱阻，得出夏熱冬冷地區(qū)建筑節(jié)能應綜合考慮保溫與隔熱兩種工況，選擇最優(yōu)值，不能一味的追求圍護結構傳熱系數(shù)的降低。
[Abstract]:Energy saving and emission reduction is an important way to reduce environmental pollution and solve the energy crisis. Building energy consumption accounts for about 30% of the total energy consumption. With the development of urbanization and the adjustment of industrial structure, the proportion of building energy consumption will continue to increase. To achieve the goal of energy saving of 65%, it is necessary to improve the insulation performance of the enclosure. At present, there is still a certain gap between the external wall insulation and heat insulation technology in our country, so it is necessary to do a good job of blocking the thermal bridge and air partition of the external wall insulation system with reference to the foreign development experience. This is of great significance to the development of building energy conservation in China. This paper takes the integrated exterior wall insulation system as the research object, and analyzes the influence of the air interlayer shape size on the thermal insulation performance of the integrated external wall insulation system by means of theoretical calculation of CFD simulation of energy consumption analysis and measured data. First of all, this paper describes the installation methods and characteristics of the external wall insulation system commonly used in our country, the treatment methods of the main nodes in the installation process, and enumerates the advantages and disadvantages of the wet and dry installation methods. It is pointed out that the introduction of air interlayer can improve the thermal insulation performance of dry installation method. In the third chapter, the typical structure of the integrated exterior wall insulation system is introduced, and the heat transfer theory of the system is analyzed according to the Fourier law of heat transfer and the Graschev criterion, and the system is simplified into a physical model. According to the climatic conditions in Hefei area, the boundary conditions are determined, and the above problems are simplified to two-dimensional steady-state heat transfer temperature. The CFD simulation is carried out. The effect of air interlayer setting size on the heat transfer performance of the system is studied and the optimal installation size for engineering application is determined. In chapter 4, according to the calculation of the optimum size above, the indoor temperature of 8760h is simulated by using DeST building energy analysis software in the project of Paramount Shangze International Office Building, which is a demonstration project. According to the previous research on indoor comfort, the time of heating and air conditioning in summer is determined, and suggestions for building energy saving in hot summer and cold winter area are put forward. Finally, the temperature and heat flux data collected in the laboratory are statistically analyzed, and the temperature distribution measured in real time in the last two years is analyzed. The thermal resistance in December, January and summer July and August in winter is calculated by combining the data collected by heat flux collection. It is concluded that building energy conservation in hot summer and cold winter area should consider heat preservation and heat insulation comprehensively and select the optimum value, so that the decrease of heat transfer coefficient of enclosure structure should not be pursued blindly.
