【摘要】：門窗與幕墻是建筑圍護(hù)結(jié)構(gòu)節(jié)能最重要的環(huán)節(jié),通過(guò)門窗與幕墻的熱損失占建筑總能耗的40%~50%,我國(guó)的門窗節(jié)能技術(shù)發(fā)展緩慢、產(chǎn)品結(jié)構(gòu)單一,節(jié)能效率低下。而幕墻推廣迅速,面積占建筑外圍護(hù)結(jié)構(gòu)的比重越來(lái)越大,通過(guò)幕墻損失的能耗也越多。為了滿足我國(guó)“十二五”規(guī)劃中建筑節(jié)能的目標(biāo),發(fā)展節(jié)能門窗,對(duì)現(xiàn)有門窗進(jìn)行節(jié)能改造,研發(fā)新型節(jié)能幕墻,推廣使用新型節(jié)能門窗與幕墻系統(tǒng)勢(shì)在必行。本文研究國(guó)內(nèi)外門窗與幕墻節(jié)能技術(shù)存在的問(wèn)題和發(fā)展趨勢(shì),對(duì)長(zhǎng)沙地區(qū)的門窗與幕墻節(jié)能技術(shù)應(yīng)用進(jìn)行優(yōu)化設(shè)計(jì)。本文在分析長(zhǎng)沙地區(qū)的地埋位置和氣候特點(diǎn)的基礎(chǔ)上,對(duì)現(xiàn)有的門窗與幕墻節(jié)能技術(shù)進(jìn)行闡述,提出門窗與幕墻節(jié)能技術(shù)改進(jìn)的方法。分別從建筑用玻璃,門窗與幕墻鋁型材結(jié)構(gòu)、密封材料、五金件的選用等多方面進(jìn)行綜合研究,對(duì)門窗與幕墻的節(jié)能技術(shù)進(jìn)行集成優(yōu)化,設(shè)計(jì)出適合于長(zhǎng)沙地區(qū)的門窗與幕墻節(jié)能系統(tǒng)。本文對(duì)長(zhǎng)沙市某典型公寓和商業(yè)建筑的門窗與幕墻系統(tǒng)進(jìn)行集成優(yōu)化設(shè)計(jì),并采用粵建科MQMC軟件進(jìn)行熱工性能計(jì)算和對(duì)比分析,得出在相同環(huán)境條件下,采用同一種玻璃的隱框幕墻的傳熱系數(shù)比窗戶要小,結(jié)構(gòu)更加簡(jiǎn)單。綜合考慮成本和節(jié)能效果,可以優(yōu)先考慮采用增加鋼襯的斷橋隔熱門窗作為外圍護(hù)結(jié)構(gòu)。最后將集成研究方法應(yīng)用于高層建筑的單元幕墻系統(tǒng),分析現(xiàn)有單元式幕墻存在鋁材耗量大、面板玻璃破損不易更換和節(jié)能效果不佳的特點(diǎn),設(shè)計(jì)出兩種適合于長(zhǎng)沙地區(qū)的單元幕墻系統(tǒng):一種是對(duì)單元隱框幕墻的鋁型材進(jìn)行優(yōu)化,增加部分鋼襯加強(qiáng),節(jié)約成本顯著;一種是將斷橋隔熱技術(shù)引入明框單元式幕墻系統(tǒng),節(jié)能效果更好。并對(duì)隱框單元式幕墻進(jìn)行四性實(shí)驗(yàn)驗(yàn)證,結(jié)果表明設(shè)計(jì)的隱框單元式幕墻系統(tǒng)各項(xiàng)性能均達(dá)到了國(guó)標(biāo)最高性能要求。同時(shí)對(duì)兩種幕墻進(jìn)行熱工和經(jīng)濟(jì)對(duì)比分析,得出單元斷橋明框幕墻的傳熱系數(shù)比單元隱框幕墻小了22%,每年可以節(jié)省空調(diào)電費(fèi)約9%。
[Abstract]:Windows, doors and curtain walls are the most important links in building envelope structure energy saving. The heat loss of doors, windows and curtain walls accounts for 40% of the total building energy consumption. The energy saving technology of doors and windows in China is slow, the product structure is single, and the efficiency of energy saving is low. But the curtain wall popularizes rapidly, the area occupies the building outer enclosure structure proportion more and more, through the curtain wall loss energy consumption also more. In order to meet the goal of building energy saving in the 12th Five-Year Plan of our country, it is imperative to develop energy-saving doors and windows, to carry out energy saving transformation of existing windows and doors, to develop new energy-saving curtain walls, and to popularize the use of new energy-saving doors, windows and curtain wall systems. In this paper, the problems and development trend of energy saving technology of doors, windows and curtain walls at home and abroad are studied, and the optimization design of the application of energy saving technology of doors, windows and curtain walls in Changsha area is carried out. Based on the analysis of the buried location and climatic characteristics of Changsha area, this paper expounds the existing energy-saving technology of doors and windows and curtain walls, and puts forward the methods to improve the energy-saving technology of doors, windows and curtain walls. From the aspects of glass, door and window and curtain wall aluminum profile structure, sealing material, hardware selection and so on, the energy saving technology of door, window and curtain wall is integrated and optimized. The energy saving system of doors and windows and curtain wall suitable for Changsha area is designed. In this paper, the integrated optimization design of doors and windows and curtain wall system of a typical apartment and commercial building in Changsha is carried out, and the thermal performance is calculated and compared by using the MQMC software of Yuejianke, and it is concluded that under the same environmental conditions, The heat transfer coefficient of the curtain wall with the same glass is smaller than that of the window, and the structure is simpler. Considering the cost and energy saving effect, the insulation doors and windows of broken bridge with additional steel lining can be preferred. Finally, the integrated research method is applied to the unit curtain wall system of high-rise building, and the characteristics of the existing unit curtain wall are analyzed, such as the large consumption of aluminum material, the difficult replacement of panel glass and the poor energy saving effect. Two kinds of unit curtain wall system suitable for Changsha area are designed: one is to optimize the aluminum profile of the unit hidden frame curtain wall, and the other is to introduce the technology of broken bridge heat insulation into the open frame unit curtain wall system. The energy saving effect is better. The experimental results show that all the performances of the system are up to the highest performance requirements of the national standard. At the same time, the heat transfer coefficient of the two kinds of curtain wall is 22 less than that of the hidden frame curtain wall, which can save about 9 percent of the electricity cost of air conditioning every year by comparing the heat transfer coefficient of the two kinds of curtain walls with those of the two kinds of curtain walls.
