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。
The method of determining outdoor air calculation parameters of GB 50736-2012 “Code for Design of Heating, Ventilation and Air Conditioning of Civil Buildings” was introduced. The difference between this method and developed countries, the selection principle of meteorological station and the definition of statistical period are mainly introduced. The variation regularity of meteorological data is analyzed. The calculated temperature in winter shows an upward trend and changes obviously. Most of the cities in summer have a rising temperature Trend, but the change is smaller, some cities slightly lower.
