［摘要］通過(guò)試驗(yàn)測(cè)定和數(shù)值模擬兩種方法研究常用輕型木結(jié)構(gòu)墻體的平均傳熱系數(shù)及其在嚴(yán)寒和寒冷地區(qū)各氣候分區(qū)中節(jié)能設(shè)計(jì)的適用性。針對(duì)兩種輕型木結(jié)構(gòu)墻體，研究得出未做外保溫的墻體1不適用于嚴(yán)寒A區(qū)3層以下的建筑，采用了30mm厚的EPS外保溫的墻體2適用于嚴(yán)寒和寒冷地區(qū)所有層數(shù)居住建筑節(jié)能設(shè)計(jì)，兩種墻體均可滿足北京地區(qū)居住建筑75%的節(jié)能標(biāo)準(zhǔn)要求。通過(guò)數(shù)值模擬獲得的外墻平均傳熱系數(shù)與實(shí)測(cè)結(jié)果具有較好的一致性，該模擬方法對(duì)于其他輕質(zhì)木結(jié)構(gòu)復(fù)合墻體的節(jié)能設(shè)計(jì)具有一定的借鑒意義。

Abstract:Two methods of experimental measurement and numerical simulation were used to study the average heat transfer coefficient of commonly used light timber structure walls and their applicability in energy conservation design in severe cold and cold regions. According to the two kinds of light timber structure walls, study results show that wall 1 without external insulation does not apply to the buildings with less than 3 stories in severe cold region A, and wall 2 with 30mm thick EPS external insulation can apply to the energy conservation design in buildings with all stories in severe cold and cold regions. These two kinds of walls could meet the 75% requirements of residential building energy efficiency standards of Beijing. The mean heat transfer coefficient for external wall obtained by numerical simulation was in good agreement with the measured results. The simulation method had a certain reference significance for other light timber composite wall energy conservation design.

Keywords:light timber structure wall; building energy conservation; numerical simulation; average heat transfer coefficient of external wall
