摘要
研究了模拟寒冷地区自然通风模式下不同形状系数瘦高中庭温度的垂直分布.研究发现当瘦高中庭形状系数小于0. 16 时(定义形状系数小于0. 16 的中庭为超瘦高中庭),中庭顶部的温度随着形状系数的减小而降低.通过建立物理模型,探讨了不同形状系数的瘦高中庭温度垂直分布,超瘦高中庭垂直温度分布规律,以及相应的影响因素,对此类建筑的防火设计提供参考.
Abstract
The vertical distribution of temperature in high atrium with different shape coefficient under simulated natural ventilation mode of cold region was studied. It was found that for an atrium with a shape coefficient less than 0. 16 (the atrium is defined as high atrium if the factor is less than 0. 16),the temperature at its top part decreased by its shape coefficient decreasing. By establishing physical model,the authors probed into the vertical temperature distributed in high atrium with different shape coefficient, temperature distribution pattern in ultra-high atrium and influencing factors accordingly to provide reference for the fire protection design of this building type.
