【摘要】：隨著我國經(jīng)濟(jì)的不斷發(fā)展和人民生活水平的提高,建筑行業(yè)隨之發(fā)展迅速,建筑能耗不斷增長,這已經(jīng)成為制約我國經(jīng)濟(jì)發(fā)展的重要因素之一。而在既有建筑中,工業(yè)建筑單位面積能耗遠(yuǎn)高于居住建筑,工業(yè)建筑的能耗在總建筑能耗中占相當(dāng)大的比重。寒冷地區(qū),建筑能耗以采暖能耗為主,而寒冷地區(qū)的建筑能耗的很大一部分是通過外圍護(hù)結(jié)構(gòu)損失掉的。寒冷地區(qū)建筑圍護(hù)結(jié)構(gòu)的節(jié)能設(shè)計(jì)關(guān)系到整個(gè)建筑的節(jié)能效益,對其進(jìn)行節(jié)能改造,節(jié)能潛力非常顯著。因此,研究寒冷地區(qū)既有采暖工業(yè)建筑的節(jié)能改造措施意義重大。首先,本文通過文獻(xiàn)閱讀、現(xiàn)場調(diào)研等方法,總結(jié)了寒冷地區(qū)工業(yè)建筑的發(fā)展歷史和圍護(hù)結(jié)構(gòu)的現(xiàn)狀及存在的問題。通過測試西安某一典型既有采暖工業(yè)建筑,分析其圍護(hù)結(jié)構(gòu)的現(xiàn)狀,得出該工業(yè)建筑圍護(hù)結(jié)構(gòu)的保溫性能較差,建筑能耗非常大,計(jì)算了該工業(yè)建筑各圍護(hù)結(jié)構(gòu)耗熱量占總建筑能耗的比重,其中屋面的耗熱量占總耗熱量的比重最大,其次為外墻與外窗。其次,總結(jié)了針對寒冷地區(qū)既有工業(yè)建筑各圍護(hù)結(jié)構(gòu)節(jié)能改造常用的技術(shù)措施,主要包括外墻、外窗和屋頂?shù)墓?jié)能改造技術(shù)。對比分析了輻射采暖與對流采暖兩種不同的采暖方式對建筑能耗的影響,對工業(yè)建筑適宜的采暖方式進(jìn)行了簡單的探討。最后,借助DeST-c建筑能耗模擬軟件,對西安地區(qū)某一典型既有采暖工業(yè)建筑的建筑能耗進(jìn)行模擬。模擬分析該建筑分別采用不同墻體保溫、不同屋面保溫及不同熱工性能的節(jié)能窗對建筑能耗的影響以及節(jié)能效果。因工業(yè)建筑尚沒有專項(xiàng)的節(jié)能設(shè)計(jì)標(biāo)準(zhǔn),在分析過程中參照《公共建筑節(jié)能設(shè)計(jì)標(biāo)準(zhǔn)》的相關(guān)參數(shù)。通過分析得出該建筑要滿足《公共建筑節(jié)能設(shè)計(jì)標(biāo)準(zhǔn)》中關(guān)于外墻、屋面及外窗傳熱系數(shù)規(guī)定中的極限值時(shí),外墻和屋面采用不同保溫材料時(shí)所對應(yīng)的最經(jīng)濟(jì)厚度以及外窗的最優(yōu)選擇。綜合考慮外墻、屋面和外窗對建筑能耗的影響,在滿足節(jié)能65%標(biāo)準(zhǔn)的前提下,最終得出適合該工業(yè)建筑節(jié)能改造的最優(yōu)組合方案。
[Abstract]:With the development of Chinese economy and the improvement of people's living standard, the construction industry has developed rapidly and the energy consumption of building has been increasing, which has become one of the important factors restricting the economic development of our country. In the existing buildings, the energy consumption per unit area of industrial buildings is much higher than that of residential buildings, and the energy consumption of industrial buildings accounts for a large proportion of the total building energy consumption. In cold regions, building energy consumption is dominated by heating energy consumption, while a large part of building energy consumption in cold regions is lost through outer enclosure structure. The energy-saving design of building envelope structure in cold area is related to the energy saving benefit of the whole building. Therefore, it is of great significance to study the energy saving measures of existing heating industrial buildings in cold areas. Firstly, this paper summarizes the development history of industrial buildings in cold areas and the present situation and existing problems of enclosure structure through literature reading, field investigation and other methods. By testing a typical existing heating industrial building in Xi'an and analyzing the present situation of its enclosure structure, it is concluded that the thermal insulation performance of the envelope structure of the industrial building is poor, and the building energy consumption is very large. The proportion of heat consumption in the total building energy consumption of each enclosure structure of the industrial building is calculated. The heat consumption of the roof is the largest in the total energy consumption, followed by the exterior wall and the outer window. Secondly, the paper summarizes the common technical measures of energy saving reconstruction for the existing industrial buildings in cold area, including the energy saving reconstruction technology of exterior wall, outer window and roof. The effects of radiation heating and convection heating on building energy consumption are analyzed, and the suitable heating methods of industrial buildings are discussed briefly. Finally, with the aid of DeST-c building energy consumption simulation software, the energy consumption of a typical existing heating industrial building in Xi'an is simulated. The effects of different wall insulation, different roof insulation and different thermal properties on the energy consumption of the building were simulated and analyzed. Since there is no special energy-saving design standard for industrial buildings, the relevant parameters of the Standard for Energy-saving Design of Public buildings are referred to in the process of analysis. Through the analysis, it is concluded that the building should meet the limit value of the heat transfer coefficient of exterior wall, roof and outer window in the Standard of Energy Saving Design of Public Building, when the limit value of the heat transfer coefficient of exterior wall, roof and outer window is obtained. The economic thickness of the exterior wall and roof with different insulation materials and the optimal selection of the outer window. Considering the influence of exterior wall, roof and exterior window on building energy consumption, the optimal combination scheme suitable for energy saving reconstruction of industrial building is obtained under the premise of meeting the energy saving standard of 65%.
