为比较不同原始数据来源所引起的暖通设计温度差异,以中国建筑热工设计分区的五个典型代表城市1971~2000年的调和分析和三次样条逐时干球温度结果,采用ASHRAE不保证率方法统计了供暖设计温度和空调设计温度,定量分析了ASHRAE设计温度以及中国规范中的供暖室外计算温度和夏季空调室外计算干球温度的差异,以及对典型代表城市耗热量的影响.结果表明调和分析方法比三次样条方法具有略高的极端高温和略低的极端低温,调和分析和三次样条计算结果均能基本反映当地温度特征.中国地面台站观测气象数据与ASHRAE逐时气象数据在供暖设计干球温度和制冷设计干球温度的绝对误差分别约为-1.0℃和0.6℃,所引起的围护结构耗热量的绝对误差约为0.9 W/m~2,且在三次样条方法下的供暖设计温度和围护结构耗热量更接近于ASHRAE设计值与其耗热量结果.
In order to compare the differences of HVAC design temperature caused by different original data sources, and based on the harmonic analysis of the five representative cities in China’s thermal design district from 1971 to 2000 and the cubic spline dry-bulb temperature results, ASHRAE does not guarantee Rate method of heating design temperature and air conditioning design temperature, quantitative analysis of the ASHRAE design temperature and the Chinese specification of the outdoor heating temperature calculated in summer and outdoor air-conditioned dry bulb temperature differences, and the typical representative of the city’s heat consumption results show that The harmonic analysis method has a slightly higher extreme high temperature and a slightly lower extreme low temperature than the cubic spline method, and both harmonic analysis and cubic spline calculation results can basically reflect the local temperature characteristics.Chinese ground station observation meteorological data and ASHRAE hourly meteorological data The absolute error of the dry bulb temperature in the design of the heating and the dry bulb temperature of the cooling design are about -1.0 ℃ and 0.6 ℃ respectively. The absolute error of the heat consumption of the enveloping structure is about 0.9 W / m ~ 2, The heating design temperature and the heat consumption of the enclosure under the method are closer to the ASHRAE design values and their heat consumption results.
