この概要は現在英語のみで提供しています。

適用範囲

This standard applies to electric fans driven by AC or DC motors, including table fans, louver fans, wall fans, table-floor fans, pedestal fans, and ceiling fans. It covers single-phase rated voltages not exceeding 250V and other rated voltages not exceeding 480V. It is mandatory for all manufacturers producing these fan types for the Chinese market. The standard specifically excludes products that cannot be classified under the aforementioned categories.

技術要求

The standard classifies electric fan energy efficiency into 3 grades, where Grade 1 represents the highest efficiency. It establishes the minimum allowable values of energy efficiency (Grade 3) which serve as the mandatory market access threshold. A major requirement introduced in this version is the limitation of standby power. The standard sets specific maximum limits for standby power consumption, differentiating between fans with and without information or status display functions. Products exceeding these standby power limits cannot achieve the corresponding energy efficiency grade. Additionally, the standard defines a specific category known as wind gathering fans. For these specific fan types, a correction coefficient (λ) is applied during the energy efficiency calculation to account for their concentrated airflow characteristics, as detailed in the referenced Appendix A.

試験方法

Testing procedures involve measuring the input power and air volume of the fan, which must be conducted in accordance with GB/T 13380-2018 and QB/T 5262-2018. Standby power is measured according to GB/T 35758-2017. For identifying wind gathering fans, the inner and outer circle air volumes are tested and calculated based on specific radius ranges. Manufacturers must ensure their testing facilities are equipped to perform these specific Chinese standard test methods.

よくある質問

What products are regulated under GB 12021.9-2021?

The standard applies to table fans, louver fans, wall fans, table-floor fans, pedestal fans, and ceiling fans driven by AC or DC motors, with specific voltage limits. It is mandatory for all manufacturers targeting the Chinese market.

Are there any significant updates from the previous GB 12021.9-2008 version?

The main updates include the addition of DC motor-driven fans, the introduction of standby power requirements, updated energy efficiency values for each grade, and a new calculation method featuring a correction coefficient for wind gathering fans.

How are the energy efficiency values tested and calculated?

Testing is conducted according to referenced national standards such as GB/T 13380-2018 for AC fans, QB/T 5262-2018 for DC fans, and GB/T 35758-2017 for standby power measurement. Manufacturers must ensure their testing facilities or partners are equipped to perform these specific Chinese standard tests.
