摘　　要：随着建筑节能改造及空调供热系统的优化运行改造项目的飞快发展,节能量的测量验证的准确程度及经济性问题日益突出。本研究针对其准确程度的指标不确定度与建模样本数量的关系,结合经济性分析及实际工程计算,首次揭示了不确定度与建模样本数量的关系,最终确定了既可保证准确度又兼顾经济性的样本量选取方法,为供热系统节能改造的节能量测量验证的样本数的确定提供一定的指导。With the rapid development of energy saving reformation for air conditioning and heating system,the measurement and verification of energy saving is becoming more and more important. But there is no data to support the relation between degree of accuracy and the number of samples. This paper analyzed the relation between uncertainty and the number of samples based on data of an actual project. The relationship between the degree of uncertainty and the number of the sample is first revealed in this paper and the sample size selection method which can ensure accuracy and balance the economic performance is determined. This method provides some guidance for the energy saving of heating system.
