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.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in GB/T 7725-2004 and JB/T 13573-2018 as well as the following apply.
3.1
minimum allowable values of energy efficiency for room air conditioners
minimum allowable value of energy efficiency during cooling and heating operation under specified working conditions
3.2
minimum allowable values of energy efficiency for low ambient temperature air source heat pump air heaters
minimum allowable value of the heating seasonal performance factor during heating operation under specified working conditions
3.3
energy consumption in standby mode
energy consumption of the product when powered on but in a non-working state; standby mode is the lowest energy consumption mode of the appliance, in which, the appliance timely monitors the control signals from the remote control device, internal sensor or similar devices that enable it to enter the working state
Note: in this mode, the input power of protection devices with similar functions such as crankcase heater is not included.
