本文提出了一种估算空调运行期能量需要量的简捷计算方法——当量峰值小时数法。叙述了进行数理统计所取用气象参数的数字模型,并以上海地区的实际气象资料为依据提出了适于工厂、宾馆、办公楼和百货大楼用的计算当量峰值小时数的回归公式。最后举例说明了用本方法计算建筑物空调运行期能量需要量的计算方法。 This paper proposes a simple calculation method for estimating the energy requirements of air-conditioning operating hours - equivalent peak hours method. The digital model for meteorological parameters taken by mathematical statistics was described. Based on the actual meteorological data in Shanghai, a regression formula for calculated equivalent peak hours for factories, hotels, office buildings and department stores was proposed. Finally, an example is given to illustrate the calculation method for calculating the energy requirements of the air conditioner during the operation period of the building using this method.
