GB 12021.3-2000: The limited values of energy efficiency and evaluating values of energy conservation for room air conditioners

Last updated: 16 April 2021

Applies to air-cooling condensor, completely closed type electric motor-compressor type AC, whose cooling capacity is below 14000W and climate type is T1. Doest Not apply to multi-split, portable and variable speed room air conditioners.

 

Unitary type:  

  • CC  = 4500: EER for cooling 2.25, EER for cooling and heating 2.15

 

Split type:  

  • CC = 2500:  EER for cooling 2.50, EER for cooling and heating 2.40;
  • 2500 < CC = 4500:  EER for cooling 2.45, EER for cooling and heating 2.35;
  • 4500 < CC = 7100:  EER for cooling 2.40, EER for cooling and heating 2.30;
  • 7100 < CC = 14000:  EER for cooling 2.30, EER for cooling and heating 2.25

 

CC= cooling capacity expressed in W

EER= energy efficiency ratio W/W
