【摘要】：隨著我國(guó)經(jīng)濟(jì)發(fā)展的穩(wěn)定增長(zhǎng)與城市人口密度的顯著增加,城市住宅需求總量得到迅速增長(zhǎng),但同時(shí)住宅老化問(wèn)題也越來(lái)越嚴(yán)重。大連市地處我國(guó)北方寒冷地區(qū),冬季較長(zhǎng)且寒冷干燥,極端條件下冬季室內(nèi)外溫差可高達(dá)35℃以上,對(duì)住宅進(jìn)行全面供暖來(lái)保證室內(nèi)溫度。夏季,大連地區(qū)住宅室內(nèi)較為涼爽,但是在八月份極度悶熱的情況下,建筑具有較好的防暑降溫性能亦是非常必要的。因此,對(duì)既有建筑實(shí)施更新,即實(shí)行暖房工程勢(shì)在必行。為了研究既有建筑通過(guò)改造后,對(duì)室內(nèi)熱環(huán)境的改善效果,本研究以大連市的暖房工程為例,進(jìn)行了如下研究：首先,對(duì)大連市既有建筑存在的問(wèn)題進(jìn)行了調(diào)查,總結(jié)了建筑老化問(wèn)題對(duì)人體健康及居住環(huán)境產(chǎn)生的負(fù)面影響,并分析了既有建筑現(xiàn)階段存在的實(shí)際應(yīng)用問(wèn)題；其次,針對(duì)建筑圍護(hù)結(jié)構(gòu)材料熱工性能較差的問(wèn)題,對(duì)既有建筑的外墻增加了保溫層,并有針對(duì)性的給出了暖房工程節(jié)能改造技術(shù)要點(diǎn)及注意事項(xiàng)；再次,通過(guò)實(shí)測(cè)調(diào)查與能耗分析的方法,對(duì)既有建筑改造前后的室內(nèi)熱濕環(huán)境進(jìn)行了監(jiān)測(cè)與數(shù)據(jù)分析；最后,通過(guò)數(shù)據(jù)對(duì)比及能耗分析,證明既有建筑通過(guò)節(jié)能改造措施能夠有效改善室內(nèi)人居環(huán)境,降低建筑能耗。本研究成果一方面可為制定既有建筑更新改造的相關(guān)政策和執(zhí)行方案提供基礎(chǔ)依據(jù),同時(shí)為今后的住宅設(shè)計(jì)等方面提出相應(yīng)設(shè)計(jì)策略。
[Abstract]:With the stable growth of economic development and the significant increase of urban population density, the total demand for urban housing has increased rapidly, but at the same time, the problem of housing aging is becoming more and more serious. Dalian is located in the cold area of northern China, the winter is long and cold and dry, under extreme conditions, the indoor and outdoor temperature difference can be as high as 35 鈩，
