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... 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. 展开更多

This paper proposes the cooling system type and cooling equipment type which are deep mine with high temperature during the construction,and presents auxiliary cooling measures making up duct temperature rise since compression and heat transfer temperature rise. The cooling system designed against Zhaolou mine's ground temperature and weather conditions,with its sprinkler room handling an average temperature difference up to 19.5~23.8 ℃,and the average enthalpy difference could reach 48.4~60.7 kJ/kg. At the same time,it gets a series of basic data used for mine construction during the cooling system design and equipment selection according to the measured results; using the analysis software Matlab,it obtains the change relations between the temperature of sprinkler room and fan export supply air temperature,wind casing temperature rise and fan export supply air temperature,working face temperature and supply air temperature,used for the mine cooling which has the similar conditions. 展开更多
