夏(xia)熱(re)冬(dong)(dong)暖地區位于(yu)我(wo)國南部,包括海(hai)南全境(jing),廣東大部,廣西大部,福建南部,云南小(xiao)部分,以(yi)及香港、澳門(men)與臺(tai)灣.該(gai)地區為亞(ya)熱(re)帶濕潤季風氣(qi)候(hou),其特征是(shi)夏(xia)季漫長(chang),冬(dong)(dong)季寒冷時間(jian)很短(duan)或無冬(dong)(dong),長(chang)年氣(qi)溫高而且濕度大,氣(qi)溫的年較差和日較差都小(xiao).太陽輻射強烈,雨量充沛(pei).

    對(dui)于這一(yi)地(di)(di)區(qu)的建筑來(lai)說,夏(xia)(xia)季需(xu)要空調(diao),而冬(dong)(dong)季則一(yi)般不(bu)考慮采暖,根據《夏(xia)(xia)熱冬(dong)(dong)暖地(di)(di)區(qu)居(ju)住建筑節(jie)能設(she)計標(biao)準》規定(ding)外窗(chuang)(chuang)(chuang)傳(chuan)熱系數(shu)2.5~6.0W/(m2·K),建筑物(wu)外窗(chuang)(chuang)(chuang)及(ji)(ji)(ji)敞開式陽(yang)臺(tai)門(men)的氣密性(xing)(xing)等級,不(bu)應(ying)低于國家標(biao)準規定(ding)的4級.根據市場需(xu)求(qiu)以(yi)(yi)及(ji)(ji)(ji)各地(di)(di)區(qu)的氣候條(tiao)件,斷橋鋁(lv)(lv)合(he)金隔熱條(tiao)越長,保溫效果越好,但是(shi)價格也(ye)就越高,在對(dui)各種鋁(lv)(lv)合(he)金門(men)窗(chuang)(chuang)(chuang)典型(xing)分(fen)格的熱工(gong)計算中,可(ke)知通(tong)體鋁(lv)(lv)合(he)金門(men)窗(chuang)(chuang)(chuang)的K值完全可(ke)以(yi)(yi)符合(he)《夏(xia)(xia)熱冬(dong)(dong)暖地(di)(di)區(qu)居(ju)住建筑節(jie)能設(she)計標(biao)準》的要求(qiu).在夏(xia)(xia)熱冬(dong)(dong)暖地(di)(di)區(qu),夏(xia)(xia)季開空調(diao),因為玻璃(li)占了門(men)窗(chuang)(chuang)(chuang)大部分(fen)面積(ji),夏(xia)(xia)季室內溫度(du)升高主要是(shi)透(tou)過(guo)玻璃(li)的熱輻射及(ji)(ji)(ji)太陽(yang)直射,而不(bu)是(shi)鋁(lv)(lv)型(xing)材的熱傳(chuan)遞;在冬(dong)(dong)季時,由于寒冷時間(jian)很短(duan)或是(shi)沒有(you),基本上室內都不(bu)需(xu)要取暖.在夏(xia)(xia)熱冬(dong)(dong)暖地(di)(di)區(qu),鋁(lv)(lv)合(he)金門(men)窗(chuang)(chuang)(chuang)的選擇從性(xing)(xing)價比及(ji)(ji)(ji)節(jie)能需(xu)求(qiu)上,選擇通(tong)體鋁(lv)(lv)合(he)金的門(men)窗(chuang)(chuang)(chuang)就足以(yi)(yi)滿(man)足要求(qiu).
