GB 21455-2008 The minimum allowable values of the energy efficiency and energy efficiency grades for variable speed room air conditioners

Scope

This standard specifies the energy efficiency limits, energy-saving evaluation values, energy efficiency grades, test methods, and inspection rules for speed-controllable room air conditioners. This standard applies to speed-controllable room air conditioners that use air-cooled condensers and fully enclosed speed-controllable electric compressors, with a cooling capacity of less than 14,000 W, and a climate type of T1. The speed-controllable type referred to in this standard includes those that use AC frequency conversion, DC speed regulation, and other methods to change the compressor speed. This standard does not apply to portable air conditioners, fixed-speed air conditioners, and multi-unit air conditioning systems.
