Abstract: Refrigerator is a product of energy efficiency labeling management, which is an insulated box with proper volume and equipment for household use. It refrigerate by consuming electricity, with one or more compartments, including refrigerator, refrigerator-freezer, frozen compartment, frozen, wine storage appliance, etc. There are many uncertainties in the measurement of energy efficiency, so in order to measure the degree to which these uncertainties influence the results more intuitively, and conduct testing of household refrigerators with energy efficiency labeling management more standardizedly, a typical product is selected for uncertainty analysis.

Key words: Energy efficiency, Energy consumption, Uncertainty
