【摘要】：双层玻璃幕墙(Double Skin Fa(?)ade)作为一种新型建筑围护结构,能有效降低传统玻璃幕墙建筑制冷及取暖能耗,因而在现代化建筑中被广泛使用。目前国内对夏热冬冷地区双层玻璃幕墙系统的研究主要是针对其热工性能的分析,缺乏对DSF通风性能的理论研究和实测分析。本文以株洲为夏热冬冷地区的代表,选取某高校搭建的双层玻璃幕墙实验房为研究对象,结合当地的气候特征,对一年中不同季节下DSF多元通风的运行方式进行深入的分析和探讨,为实现双层玻璃幕墙建筑的最大节能效益提供理论指导。本文首先依据CFD原理,借助Fluent软件对双层玻璃幕墙在全年不同季节下不同的通风方式进行模拟分析。其中夏季主要模拟分析了外循环式双层玻璃幕墙在自然通风、机械通风及不同机械通风风速下热通道和室内空气的温度变化规律;过渡季节模拟分析了内外侧幕墙通风口的不同使用方式对热通道和室内空气温度的影响;冬季则模拟分析了内侧幕墙通风口的启闭对热通道和室内空气温度的影响。依据模拟结果,总结出了双层玻璃幕墙建筑在不同季节下合理的通风方式。随后通过实验对双层玻璃幕墙实验房在不同季节下的通风方式进行了测试,并将实验结果与模拟结果进行了对比分析,但是实验值与模拟值之间存在误差,通过分析总结了产生误差的原因。最后本文以某办公建筑为建筑模型,利用能耗模拟软件DeST模拟分析了双层玻璃幕墙和传统玻璃幕墙建筑室内自然室温在夏季和冬季工况下的变化规律及双层玻璃幕墙建筑和传统玻璃幕墙建筑的全年建筑能耗,得出在没有采取通风措施下,DSF建筑在夏热冬冷地区的节能优势并不明显。
[Abstract]:As a new type of building envelope structure, double-layer glass curtain wall (Double Skin Fa (-) ade) can effectively reduce the energy consumption of cooling and heating of traditional glass curtain wall buildings, so it is widely used in modern buildings At present, the research on the double-layer glass curtain wall system in hot summer and cold winter area is mainly aimed at the analysis of its thermal performance, and the lack of theoretical research and actual measurement analysis on the ventilation performance of DSF. This paper takes Zhuzhou as the representative of hot summer and cold winter area, selects the double-layer glass curtain wall experimental room built by a certain university as the research object, combines the local climate characteristic, This paper analyzes and discusses the operation mode of DSF multiple ventilation in different seasons of the year, which provides theoretical guidance for realizing the maximum energy saving benefit of double-layer glass curtain wall building. In this paper, according to CFD principle and Fluent software, the ventilation modes of double-layer glass curtain wall are simulated and analyzed in different seasons of the year. In summer, the temperature variation law of heat passage and indoor air under natural ventilation, mechanical ventilation and different mechanical ventilation wind speed is analyzed. In the transition season, the effects of different ways of using the vent of the inner and outer side curtain wall on the heat passage and indoor air temperature are analyzed, and the influence of the opening and closing of the inside curtain wall vent on the heat passage and indoor air temperature is simulated in winter. According to the simulation results, the reasonable ventilation mode of double-layer glass curtain wall in different seasons is summarized. Then the ventilation mode of the double-layer glass curtain wall experiment room in different seasons is tested, and the experimental results are compared with the simulation results, but there are errors between the experimental values and the simulated ones. The causes of errors are analyzed and summarized. Finally, this paper takes an office building as a building model, The energy consumption simulation software DeST is used to simulate and analyze the variation of indoor natural room temperature of double-layer glass curtain wall and traditional glass curtain wall building under summer and winter conditions, and the annual energy consumption of double-layer glass curtain wall building and traditional glass curtain wall building. It is concluded that the energy saving advantage of DSF buildings in hot summer and cold winter area is not obvious without ventilation measures.
