摘要
针对环渤海地区城市夏季高温高湿气候条件下的通风需求和寒冷冬季中的避风需求,以JGJ/T346-2014《建筑节能气象参数标准》中的典型气象年参数为基础,统计分析现有的23个城市各风向风频率风速数据,基于HJ 22-2008《环境影响评价技术导则大气环境》提出主导风向定量计算方式,结合主导风向、风频率、风速特征统计结果,综合考虑冬季避风和夏季通风问题,提出避风系数及通风系数概念,绘制各城市通、避风玫瑰图,探讨不同分类地区有利通风方向以及不利避风方向。
Aiming at ventilation requirements under high temperature and high humidity in summer and the needs for wind sheltering in chilly winters in the Bohai Rim region,based on the typical meteorological year parameters in the/T 346-2014 Building Energy Conservation Meteorological Parameter Standards,a statistical analysis of wind directions,wind frequencies and wind speed data for 23 cities,based on the old specification of HJ 22-2008,a wind directions,wind frequencies,and wind speeds,taking winter sheltering and summer ventilation intocomprehensive consideration,the concepts of ventilation coefficients and sheltering coefficients were proposed,androse maps of city ventilation or sheltering were drawn to explore the favorable ventilation directions and adversesheltering directions in different classification areas.
