家用电冰箱大幅提升能效门槛倒逼企业加速技术研发

Core Points - The new national standard GB12021.2-2025 for household refrigerators has been approved, replacing the 2015 version, marking the fifth revision since its initial establishment in 1989 [1] - The updated standard introduces a revolutionary change in the energy efficiency evaluation system, raising the efficiency requirements across all levels and providing clearer guidance for consumers [1][2] - The new standard expands its applicability to include motor-driven compression household refrigerators and semiconductor cooling devices with a volume of 60L or less, while also increasing the energy efficiency thresholds [2] Industry Impact - The new standard will officially take effect on June 1, 2026, allowing a one-year transition period for the market [2] - The significant increase in energy efficiency thresholds means that manufacturers must upgrade their technologies to comply; otherwise, existing level 1 energy efficiency products may drop to level 3 or be eliminated from the market [2] - Small and medium-sized brands face greater challenges and must accelerate technology development or adjust market positioning to meet the new standards [2] Energy Savings - For a 500L two-door refrigerator, the current level 1 energy consumption requirement is 0.92 kWh/day, which will be reduced to 0.55 kWh/day under the new standard, representing a 40% decrease in energy consumption [3] - The effective implementation of the new standard is projected to save approximately 13 billion kWh of electricity annually across the country [3]
