GB 21455-2019 Translated English of Chinese Standard. (GB 21455-2019, GB21455-2019): Minimum Allowable Values of the Energy Efficiency and Energy Efficiency Grades for Room Air Conditioners
https://www.chinesestandard.net, 20 déc. 2020 - 56 pages
This Standard specifies the energy efficiency grades, the minimum allowable values of energy efficiency and test methods for room air conditioners. This Standard is applicable to room air conditioners which adopt air-cooled condensers and fully enclosed electric compressors, and with a rated cooling capacity not greater than 14,000 W and with a climate type T1, as well as low ambient temperature air source heat pump air heaters with a nominal heating capacity not greater than 14,000 W. This Standard is not applicable to mobile air conditioners, multi-connected air conditioning units and air-duct air conditioners.
