室外空气计算参数确定方法的研究

摘要

介绍了GB 50736-2012《民用建筑供暖通风与空气调节设计规范》室外空气计算参数的确定方法.重点介绍了该方法与发达国家的差异、气象台站的选择原则及统计期的确定思路,分析了气象数据的变化规律:冬季计算温度呈上升趋势,且变化明显；夏季计算温度大部分城市呈上升趋势,但变化较小,部分城市略有降低.%Presents the method for determining outdoor design conditions in GB 50736-2012 Code for design of heating ventilation and air conditioning of civil buildings with focuses on the difference of determination methods between China and some developed countries, the selection principle of meteorological stations and the determination thought of the data statistic period. Analyses the variation regularity of meteorological data: the design temperature in winter becomes higher with obvious variances while for most cities the design temperature in summer rises with smaller differences, and for some other cities the temperature reduces to a certain degree.
