Foreword
This Standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This Standard replaces GB 19576-2004 “The minimum allowable values of the
energy efficiency and energy efficiency grades for unitary air conditioners”.
Compared with GB 19576-2004, in addition to editorial changes, the main
technical changes are as follows:
- Delete the term and definition of “Evaluating values of air conditioner energy
conservation” (see 3.2 of the 2004 edition);
- Delete “Evaluating values of energy conservation” (see 5.2 of the 2004
edition);
- REVISE the energy efficiency grade criteria of the product (see Clause 4);
- Modify the minimum allowable values of energy efficiency for the product
(see Clause 5);
- Delete inspection rules (see Clause 7 of the 2004 edition);
- Delete energy efficiency grade labeling (see Clause 8 of the 2004 edition).
This Standard was proposed by and shall be under the jurisdiction of

Minimum allowable values of energy efficiency and
energy efficiency grades for unitary air conditioners
1 Scope
This Standard specifies the energy efficiency grades, technical requirements,
and test methods for unitary air conditioners.
This Standard is applicable to unitary air conditioners using motor-driven
compressors and with indoor unit static pressure of 0 Pa (gauge pressure),
unitary air conditioners for computer and data processing room, unitary air
conditioners for communication base station, and constant temperature-and-
humidity unitary air conditioners.
This Standard does not apply to multi-connected air conditioning (heat pump)
units, rooftop air conditioner units, and air-duct air supply air conditioning (heat
pump) units.
