This national standard specifies the minimum allowable value or, evaluating values of energy conservation, energy efficiency grade, test method and inspection rules for unitary air conditioners.
This standard is applicable to unitary air conditioners as well as ducted and rooftop air conditioning units (hereafter referred to as unitary air conditioners) with nominal refrigerating capacity greater than 7100W and compressor driven by motor. This standard excludes multi-connected air conditioning (heat pump) units and frequency-conversion unitary air conditioners.
