摘要
为保证国家大剧院水(冰)下玻璃廊冬季不结露,对围护结构外表面与室外空气和天空的对流和辐射换热量进行了分析研究,确定了室外空气综合温度的数值,并代替室外空调计算温度。分别对白天和夜间不同工况的传热计算和防结露计算进行了校核。推导了夏季水下玻璃屋顶围护结构冷负荷计算方法,计算出玻璃廊的冷负荷。介绍了玻璃廊的空调气流组织形式。
To prevent the underwater glass gallery from occurring condensation in winter, analyses the convection heat transfer between external surface of enclosure and outdoor air and radiation heat transfer between external surface of enclosure and sky, determines the value of outdoor sol-air temperature and use it in place of the outdoor air conditioning calculation temperature. Calculates and checks the heat transfer and condensation prevention in the day and night under different conditions. Deduces the calculation method of summer cooling load of the underwater glass gallery envelope and calculates this part of cooling load. Describes the air distribution in the gallery.
