GB規格 21455-2019: Minimum allowable values of the energy efficiency and energy efficiency grades for room air conditioners
Description
1 Scope
This standard specifies the energy efficiency grades, minimum allowable values of the energy efficiency and test methods for room air conditioners.
This standard is applicable to the room air conditioners with air-cooled condensers, fully enclosed electric compressors, rated cooling capacity not greater than 14,000 W and climate type T1, as well as the low ambient temperature air source heat pump air heaters with nominal heating capacity not greater than 14,000W.
This standard is not applicable to portable air conditioners, VRV air conditioning units and air duct air conditioners.
