【摘要】：雙層玻璃幕墻相對(duì)于單層玻璃幕墻來(lái)說(shuō),在隔聲性能,能耗效率等方面具備一定的優(yōu)勢(shì),這使其逐漸被廣泛應(yīng)用于夏熱冬冷地區(qū)新建高層辦公建筑中。本文以杭州地區(qū)氣象條件為基礎(chǔ),通過(guò)CFD模擬手段計(jì)算實(shí)際項(xiàng)目中一種雙層玻璃幕墻的熱工特性,得到該雙層玻璃幕墻系統(tǒng)夏冬季工況下室內(nèi)得熱量與太陽(yáng)輻射及室內(nèi)外溫差之間的關(guān)系式。該關(guān)系式表征了幕墻系統(tǒng)的兩大特征：太陽(yáng)得熱系數(shù)(SHGC)和有效傳熱系數(shù)(U值)。同時(shí),根據(jù)瑞士材料實(shí)驗(yàn)所(EMPA)進(jìn)行中空玻璃窗實(shí)驗(yàn)得到的數(shù)據(jù)驗(yàn)證了該系統(tǒng)的室內(nèi)得熱和太陽(yáng)輻射及室內(nèi)外溫差之間存在關(guān)系式,為后續(xù)雙層玻璃幕墻的研究提供基礎(chǔ)。 同時(shí),還研究了通道寬度、進(jìn)出口大小和層高對(duì)于雙層玻璃幕墻系統(tǒng)室內(nèi)得熱的影響。適當(dāng)?shù)耐ǖ缹挾群瓦M(jìn)出口大小會(huì)改善雙層玻璃幕墻系統(tǒng)的熱工性能,而層高對(duì)于雙層玻璃幕墻的熱工性能的影響很小 應(yīng)用該關(guān)系式簡(jiǎn)便估算了該幕墻系統(tǒng)在杭州典型氣象年中夏季6～8月份間的冷負(fù)荷值和冬季12～2月份間的熱負(fù)荷值。選擇的雙層玻璃幕墻具有很低的太陽(yáng)得熱系數(shù),通過(guò)計(jì)算得到雙層玻璃幕墻在夏季通過(guò)減少冷負(fù)荷降低能耗,在冬季則限制了太陽(yáng)輻射的利用。該結(jié)果顯示在雙層玻璃幕墻設(shè)計(jì)的過(guò)程中,根據(jù)夏冬季氣候適應(yīng)性特征,應(yīng)將其隔熱能力和保溫能力分開(kāi)進(jìn)行研究。 末章總結(jié)了本文的主要工作(結(jié)論)、存在的問(wèn)題及進(jìn)一步展望。
[Abstract]:Compared with single-layer glass curtain wall, double-layer glass curtain wall has some advantages in sound insulation performance and energy consumption efficiency, which makes it widely used in newly built high-rise office buildings in hot summer and cold winter areas. In this paper, based on the meteorological conditions in Hangzhou, the thermal properties of a double-layer glass curtain wall in a practical project are calculated by means of CFD simulation. The relationship between indoor heat yield and solar radiation and temperature difference between indoor and outdoor is obtained under summer and winter working conditions of the double-layer glass curtain wall system. This formula represents two characteristics of curtain wall system: solar heat gain coefficient (SHGC) and effective heat transfer coefficient (U value). At the same time, according to the data obtained from the hollow glass window experiment carried out by (EMPA), a Swiss material laboratory, the relationship between indoor heat gain, solar radiation and indoor and outdoor temperature difference is verified, which provides a basis for the further study of double-layer glass curtain wall. At the same time, the influence of channel width, inlet and outlet size and layer height on indoor heat gain of double-layer glass curtain wall system is also studied. Proper channel width and inlet / exit size will improve the thermal performance of the double-layer glass curtain wall system. However, the influence of layer height on the thermal performance of double-layer glass curtain wall is very small. The formula is used to estimate the cold load value of the curtain wall system in the typical meteorological year of Hangzhou from June to August in summer and the heat load value from December to February in winter. The selected double-layer glass curtain wall has a very low solar thermal coefficient. The calculation results show that the double-layer glass curtain wall reduces the cooling load and energy consumption in summer and limits the utilization of solar radiation in winter. The results show that in the process of double-layer glass curtain wall design, according to the characteristics of climate adaptability in summer and winter, the thermal insulation ability and thermal insulation ability should be studied separately. The last chapter summarizes the main work of this paper (conclusion), the existing problems and future prospects.
