【摘要】：建筑墻體的室內(nèi)表面溫度直接反映墻體的保溫隔熱性能,并且作為室內(nèi)平均輻射溫度的主要組成部分對(duì)室內(nèi)熱環(huán)境有重要影響。針對(duì)建筑工程中大量使用的空心磚墻體具有表面溫度不均勻的特點(diǎn),采用ThermaCAM P20型紅外熱像儀和ThermaCAM Reporter分析軟件,研究應(yīng)用紅外熱像法測(cè)量空心磚墻體的表面溫度,分析空心磚墻體的溫度特征以及空心磚、砌筑砂漿、配磚等組成材料對(duì)表面溫度分布的影響。在高層住宅建筑工程現(xiàn)場(chǎng),選擇三層住宅的填充外墻位置,使用不同的燒結(jié)頁(yè)巖空心磚、砌筑砂漿和配磚砌筑成三種空心磚墻體進(jìn)行傳熱實(shí)驗(yàn)。通過(guò)采集三種燒結(jié)頁(yè)巖空心磚墻體在冬季室內(nèi)采暖條件下的內(nèi)表面溫度紅外熱像圖,對(duì)比分析了兩種空心磚和兩種砂漿砌筑的墻體表面溫度特性數(shù)據(jù)以及溫度均勻性和溫度頻率分布。結(jié)果表明:提高空心磚和砌筑砂漿的保溫性,能夠有效提高墻體內(nèi)表面溫度,改善室內(nèi)熱環(huán)境;由保溫砂漿代替水泥砂漿砌筑的節(jié)能型燒結(jié)頁(yè)巖空心磚墻體,表面溫度的不均勻性從0.6℃下降為0.4℃,并使表面溫度頻率分布發(fā)生變化,從非對(duì)稱分布變?yōu)檎龖B(tài)分布;隨著表面溫度均勻性的提高,平均溫度所占的頻率增大。本研究為空心磚墻體熱功能的提高和優(yōu)化提供了依據(jù)。
[Abstract]:The indoor surface temperature of the building wall directly reflects the thermal insulation performance of the wall, As the main component of indoor average radiation temperature, it has an important influence on indoor thermal environment. The hollow brick wall, which is widely used in building engineering, is characterized by uneven surface temperature. Using ThermaCAM P20 infrared thermal imager and ThermaCAM Reporter analysis software, the surface temperature of hollow brick wall is measured by infrared thermal image method, and the temperature characteristics of hollow brick wall and hollow brick, masonry mortar are analyzed. The influence of brick and other composition materials on surface temperature distribution. In the site of high-rise residential building, choose the position of filled exterior wall of three-story residence, use different sintered shale hollow brick, Three kinds of hollow brick walls are built by masonry mortar and brick to carry out heat transfer experiments. Infrared thermal images of the inner surface temperature of three sintered shale hollow brick walls under indoor heating conditions in winter are collected. The surface temperature characteristic data, temperature uniformity and temperature frequency distribution of two hollow bricks and two kinds of mortar masonry wall surface are compared and analyzed. The results show that increasing the temperature retention of hollow brick and masonry mortar can effectively improve the inner surface temperature of the wall. In order to improve the indoor thermal environment, the energy saving sintered shale hollow brick wall built with heat preservation mortar instead of cement mortar, the non-uniformity of surface temperature is reduced from 0.6 鈩，
