【摘要】:我國建筑能耗與其他氣候相近的發(fā)達國家相比,能耗較高;有數(shù)據(jù)顯示在建筑能耗中約有50%的能耗是由圍護結(jié)構(gòu)的設(shè)置及使用不合理造成的。而外墻在整個圍護結(jié)構(gòu)中占有的面積最大,通過外墻散失的冷熱量所占的比例就很大;因此,通過外墻保溫是實現(xiàn)建筑節(jié)能的一種很重要的方式。目前外墻保溫做法有很多種,針對夏熱冬冷地區(qū)而言,要同時滿足夏季隔熱冬季保溫及節(jié)能65%的目標(biāo),對墻體保溫系統(tǒng)做法的要求比較高;而保溫裝飾一體化系統(tǒng)在保溫隔熱方面具有很大的優(yōu)勢,因此,本文主要研究墻體外保溫中保溫裝飾一體化系統(tǒng)的熱工性能及熱橋?qū)ο到y(tǒng)傳熱的影響,作為確定該一體化系統(tǒng)在夏熱冬冷地區(qū)適用性的依據(jù)。本文主要分為以下幾個部分進行研究和分析: 首先本文闡述了目前市場上比較有代表性的保溫裝飾一體化板材,重點介紹了鋁合金聚氨酯外墻保溫裝飾一體化板材的性能及施工方案,以及其在施工質(zhì)量、工期及綜合成本方面的優(yōu)勢。 第三章主要介紹了外墻保溫系統(tǒng)中保溫裝飾一體化系統(tǒng)和保溫、裝飾相互獨立的干掛系統(tǒng)的典型構(gòu)造;從理論計算角度對幾種典型的外墻干掛系統(tǒng)的傳熱性能進行了分析,結(jié)果表明,一體化系統(tǒng)的傳熱系數(shù)與干掛石材、彩鋼板相比較小,保溫效果較好。 第四章主要介紹了熱橋的定義、危害;詳細計算了一體化系統(tǒng)中膨脹螺栓以及寬度為50mm的復(fù)合龍骨對系統(tǒng)傳熱的影響。接下來分析了不同規(guī)格的復(fù)合龍骨及金屬龍骨對傳熱系數(shù)的影響,并對實際工程中龍骨尺寸的選用提出建議。 第五章主要介紹了一體化系統(tǒng)傳熱系數(shù)現(xiàn)場測試時的測試儀器、測試方法及現(xiàn)場布點方法;對三種不同構(gòu)造系統(tǒng)的熱流及溫度進行了測量,并對最冷月、最熱月的實測數(shù)據(jù)進行了處理;由計算結(jié)果結(jié)果得到保溫效果較好的系統(tǒng)構(gòu)造做法。 第六章利用fluent軟件對有龍骨和有空氣間層(無龍骨)的一體化系統(tǒng)冬夏季的溫度分布進行模擬,并分析指出兩種工況溫度分布的不同對系統(tǒng)保溫效果的影響。
[Abstract]:Compared with other developed countries with similar climate, the building energy consumption of our country is higher, and some data show that about 50% of the building energy consumption is caused by the unreasonable installation and use of the enclosure structure. The external wall occupies the largest area in the whole enclosure structure, and the proportion of the cooling heat lost through the external wall is very large; therefore, the heat preservation through the external wall is a very important way to achieve building energy saving. At present, there are many kinds of exterior wall insulation practices. In the hot summer and cold winter area, the heat insulation and energy saving target of 65% should be met simultaneously, and the requirement of wall insulation system is relatively high. The thermal insulation system has a great advantage in heat preservation and heat insulation. Therefore, this paper mainly studies the thermal performance and the influence of heat bridge on the heat transfer of the heat preservation and decoration integration system outside the wall. As a basis for determining the applicability of the integrated system in hot summer and cold winter area. This paper is mainly divided into the following parts for research and analysis: firstly, this paper describes the representative heat preservation and decoration integrated plate on the market. This paper mainly introduces the performance and construction scheme of aluminum alloy polyurethane exterior wall heat preservation and decoration integrative plate, as well as its advantages in construction quality, construction period and comprehensive cost. The third chapter mainly introduces the typical structure of the thermal insulation and decoration integration system and the dry hanging system which is independent of each other in the external wall insulation system, and analyzes the heat transfer performance of several typical external wall dry hanging systems from the angle of theoretical calculation. The results show that the heat transfer coefficient of the integrated system is smaller than that of the dry hanging stone and the color steel plate, and the thermal insulation effect is better. In chapter 4, the definition and harm of thermal bridge are introduced, and the effects of expansion bolts and composite keel with width of 50mm on the heat transfer of the system are calculated in detail. Then, the influence of composite keel and metal keel on heat transfer coefficient is analyzed, and suggestions on the selection of keel size in practical engineering are put forward. The fifth chapter mainly introduces the testing instrument, test method and spot arrangement method of the heat transfer coefficient of the integrated system, and measures the heat flux and temperature of three different structural systems, and the coldest moon, the coldest moon and the coldest moon. The measured data of the hottest month were processed and the system construction method with better thermal insulation effect was obtained from the calculated results. In chapter 6, the temperature distribution in winter and summer of the integrated system with keel and air interlayer (without keel) is simulated by using fluent software, and the influence of different temperature distribution in two working conditions on the thermal insulation effect of the system is pointed out.
