TCVN 7830:2007, Energy efficiency ratio of air conditioners

This standard applies to air conditioners using compressed-air motor type compressors and air-cooled condensers (hereinafter referred to as equipment) with a total refrigerating capacity of up to 14 000 W ( 48,000 Btu / h). window  

 

MINIMUM ENERGY EFFICIENCY (EER in W/W, Cooling Capacity CC in W)

 

Single-split

All : 2.30 EER

 

Double-split

CC <4 500 : 2.60 W/W

4 500 = CC <7 000 : 2.50 W/W

7 000 = Q <14 000 : 2.40 W/W
