空调建筑空气幕的简化计算及其误差分析【英文篇名】 Simplified calculation and error analysis for air curtain of air-conditioned buildings 【作者中文名】 秦红; 【作者英文名】 By Qin Hong Guangdong University of Technology; Guangzhou; China; 【作者单位】 广东工业大学; 【文献出处】 暖通空调, Hv 空气幕; 计算方法; 【英文关键词】 air conditioning; air curtain; calculation method; 【摘要】 认为空气幕总作用压力由风压、热压、机械压和平衡压四项分压力组成。国内常用的空气幕设计方法是仅考虑一项分压力的简化计算方法。分析了这种简化方法的应用条件及其误差,建议冬季室内外温差大的高层建筑使用以热压为主的计算方法;而多层和排风面积比小的建筑以及夏季空调建筑,选择空气幕时应计算全部作用压力。 【英文摘要】 Thinks that the total actuating pressure of an air curtain consists of wind pressure, thermal pressure, mechanical pressure and equilibrium pressure. The design method commonly used in China is a simplified one, in which only one of the four partial pressures are considered. Analyses the application conditions and error of the simplified method. Suggests that for high-rise buildings with large temperature difference between outdoor and indoor environment in winter the calculation method mainly accounting fo...
