【摘要】:現(xiàn)代社會(huì),建筑逐漸成為資源與能源消耗的巨大載體之一,建筑節(jié)能是一個(gè)亟待研究與解決的問題。當(dāng)代建筑設(shè)計(jì)中,雙層表皮已廣泛應(yīng)用于各類建筑,特別是近年來,雙層隔熱表皮的出現(xiàn)與應(yīng)用對(duì)于被動(dòng)式建筑節(jié)能有較大促進(jìn)作用。雙層隔熱表皮主要通過外層表皮的遮陽與空氣間層的通風(fēng)作用大幅提高圍護(hù)結(jié)構(gòu)的隔熱能力。在夏熱地區(qū),良好的隔熱性對(duì)于提高圍護(hù)結(jié)構(gòu)的熱工性能及室內(nèi)的舒適性具有重要影響。但目前關(guān)于雙層隔熱表皮的研究中,主要關(guān)注其美學(xué)及經(jīng)濟(jì)方面性能,較少從構(gòu)造尺度討論隔熱表皮的節(jié)能問題。本文即從構(gòu)造尺度探討表皮開孔率及間層厚度兩個(gè)參數(shù)的取值差異對(duì)于夏熱地區(qū)雙層隔熱表皮熱工性能的影響。 文章首先梳理了國(guó)內(nèi)外關(guān)于建筑表皮、節(jié)能表皮、雙層隔熱表皮相關(guān)技術(shù)研究,接下來運(yùn)用對(duì)流·輻射·導(dǎo)熱耦合的CFD技術(shù)進(jìn)行建模,將隔熱表皮熱工性能實(shí)測(cè)結(jié)果同基于實(shí)例進(jìn)行的模擬研究結(jié)果進(jìn)行對(duì)比,驗(yàn)證了模擬方法的可靠性。然后分別就開孔率、間層厚度兩個(gè)參數(shù)的不同取值,以建筑周圍風(fēng)速、墻體表面熱流通量、墻體表面溫度為目標(biāo)因素進(jìn)行熱工性能方面的探討。結(jié)果顯示開孔率越小隔熱性能越好,而在本研究中間層厚度對(duì)于隔熱性能的影響不明顯。根據(jù)結(jié)論,文章最后選取實(shí)測(cè)實(shí)例進(jìn)行進(jìn)一步研究,結(jié)果顯示隔熱表皮具有優(yōu)良的隔熱性能,且若保持間層厚度不變、減小實(shí)例中表皮開孔率,其隔熱性能會(huì)更好。最后,對(duì)整個(gè)工作進(jìn)行總結(jié),提出若干未來相關(guān)研究的發(fā)展方向。
[Abstract]:In modern society, architecture has gradually become one of the huge carriers of resources and energy consumption. Building energy conservation is an urgent problem to be studied and solved. In contemporary architectural design, double layer epidermis has been widely used in all kinds of buildings, especially in recent years, the appearance and use of double layer heat insulation epidermis have a great effect on the energy saving of passive buildings. The heat insulation of the layer is largely enhanced by the shading of the outer skin and the ventilation of the air interlayer. In the summer heat area, good heat insulation has an important effect on improving the thermal performance of the enclosure and the comfort of the enclosure. And economic performance, less energy saving of heat insulation epidermis is discussed from the structural scale. This paper is to discuss the effect of the difference of the two parameters of the epidermal opening rate and the thickness of the interlayer thickness on the thermal performance of the double layer heat insulation skin in the hot area from the structural scale.
The paper first combed the domestic and foreign research on the building skin, the energy saving skin and the double-layer heat insulation skin related technology. Then, the modeling was carried out by the CFD technology of convection, radiation and heat conduction. The experimental results of the thermal performance of the heat insulation skin were compared with the simulation results based on the example, and the reliability of the simulation method was verified. After the different values of the opening rate and the thickness of the interlayer thickness, the thermal properties of the surrounding wind speed, the heat flux of the wall surface and the wall surface temperature are discussed. The results show that the smaller the opening rate is, the better the heat insulation performance is, and the effect of the thickness of the middle layer on the heat insulation performance is not obvious. According to the results, the effect of the thickness of the middle layer on the heat insulation performance is not obvious. At the end of this paper, we choose the actual actual example to further study it. The results show that the heat insulation skin has excellent heat insulation performance, and if the thickness of the interlayer is kept constant, the skin opening rate in the case can be reduced and the heat insulation performance will be better. Finally, the whole work is summarized, and the direction of the future related research is put forward.
