Abstract：An experimental research was conducted on the changes in energy efficiency grades of typical commercial refrigeration appliances under the GB 26920-2024 standard,and the maximum allowable values of energy consumption and the variation range of energy efficiency grades were analyzed.The results show that,the GB 26920-2024 standard significantly raises the energy-saving requirements for vertical display freezer,horizontal display freezer and stainless steel refrigerators.Compared with the current standard GB 26920.2-2015,the maximum allowable values of energy consumption of vertical display freezer and stainless steel refrigerators decreased by 24％to 35％under the GB 26920-2024 standard,and the energy efficiency grades dropped by 2 to 3 grades.The maximum allowable values of energy consumption of horizontal display freezer decreased by 16％,and the energy efficiency grade dropped by 1 to 2 grades.The requirements for commercial ice makers under the GB 26920-2024 standard are relatively moderate.Ice makers with R290 refrigerant system can reach the energy efficiency grade 1 and with R404A refrigerant system can reach the energy efficiency grades 2 to 3.
