家用电冰箱能效指数的测量不确定度评定

Evaluation of Measurement Uncertainty of Energy Efficiency Index of Household Refrigerator

我国实行家用电冰箱能效等级标识制度已有十余年,由于能效等级是通过电冰箱型号与能效指数确定,因此本文对一典型型号电冰箱做测量不确定度评定,以便直观分析电冰箱能效指数的评估中,各不确定因素带来的影响。

It has been more than ten years since the domestic refrigerator energy efficiency grade labeling system was implemented in China, and the energy efficiency grade was determined by refrigerator model and energy efficiency index.Therefore, this paper takes a typical refrigerator model as an example to evaluate the measurement uncertainty, so as to intuitively analyze the influence of various uncertainty factors in obtaining the energy efficiency index of refrigerator.
