ratio", "input power of purification", "standby power" and “minimum
allowable values of energy efficiency” (see Chapter 3; see Chapter 3 of the
2018 edition);
d) The terms and definitions of "clean air delivery rate of particle" and
"purification efficiency of gaseous pollutants" are deleted (see Chapter 3 of
the 2018 edition);
e) The classification method of "Category I products" and "Category II products"
is modified (see 4.1; see Chapter 4 of the 2018 edition);
f) The requirements for energy efficiency ratio and standby power are modified
(see 4.1; see Chapter 4 of the 2018 edition);
g) The requirements for measured and nominal values of energy efficiency ratios
and for energy efficiency grades and nominal grades are added (see 4.2);
h) The test method for "particulate matter clean air delivery rate" is modified (see
6.1.1; see 6.1.1.1 of the 2018 edition);
i) The test method for "gaseous pollutant clean air delivery rate" is added (see
6.1.2);
j) The test method for "purification efficiency of gaseous pollutants" is deleted
(see 6.1.2 of the 2018 edition);
k) The test method for "input power of purification" is modified (see 6.1.3; see
6.1.1.2 of the 2018 edition);
Minimum allowable values of energy efficiency and energy
efficiency grades for air cleaner
1 Scope
This document specifies the energy efficiency grades, technical requirements, and
testing and calculation methods for air cleaners.
This document applies to:
-- air cleaners with a single-phase rated voltage greater than 5 V and not exceeding
250 V, and other rated voltages not exceeding 480 V;
-- air cleaners with the function of removing particulate matter and gaseous
pollutants;
-- Humidifying purifier and purification fan with independent air purification
function modes.
This document does not apply to:
-- components and modules with air purification functions;
-- wearable air cleaners;
-- duct purification devices and other similar air cleaners;
-- air cleaners designed for industrial use, medical use and vehicles;
-- air cleaners used in special environments with corrosive or explosive gases (such
as dust, steam or methane gas).
2 Normative references
The provisions of the following documents constitute the essential clauses of this
document through normative references in this text. Among them, for referenced
documents with dates, only the versions corresponding to the dates are applicable to
this document; for referenced documents without dates, the latest versions (including
all amendments) are applicable to this document.
GB 12021.9 Minimum allowable values of energy efficiency and energy efficiency
grades for electric fans
4.2 The actual measured value of the energy efficiency ratio of the air cleaner shall not
be lower than 90% of the nominal value, and the energy efficiency grade shall not be
lower than the nominal grade.
5 Technical requirements
The minimum allowable values of energy efficiency of air cleaners are Grade 3 of the
energy efficiency grades in Table 1.
6 Test and calculation methods
6.1 Energy efficiency ratio
6.1.1 Particulate matter clean air delivery rate test method
The particulate matter clean air delivery rate test is carried out after the following
conditions are met:
a) General test conditions shall meet the requirements of 6.1 of GB/T 18801-
2022;
b) The measuring instruments used for the test shall meet the requirements of 6.2
and A.2.1 of GB/T 18801-2022;
c) The test chamber shall meet the requirements of 6.3 of GB/T 18801-2022
when the volume of the test chamber is above 30 m3; if a test chamber of other
volumes is used for testing, the method applicability verification shall be
passed;
d) The placement of the sample machine to be tested shall comply with the
requirements of 6.4 of GB/T 18801-2022;
e) The target pollutant used in the test is cigarette smoke.
The particulate matter clean air delivery rate shall be tested under rated conditions in
accordance with the method specified in Appendix A of GB/T 18801-2022, expressed
as Qparticulate, and the results shall be rounded to integers. When the sample machine to
be tested is a Category II product, the test shall be carried out in the air purification
function mode. If the sample machine to be tested has no rated conditions, the test is
carried out at the highest wind speed gear by default.
6.1.2 Gaseous pollutant clean air delivery rate test method
The gaseous pollutant clean air delivery rate test is carried out after the following
conditions are met:
a) The test environment conditions shall meet the requirements of E.2.1 of GB/T
18801-2022, and other conditions shall meet the requirements of 6.1 of GB/T
18801-2022;
b) The measuring instruments used for the test shall comply with the
requirements of 6.2 and E.2.2 of GB/T 18801-2022;
c) The test chamber shall meet the requirements of 6.1.1c);
d) The placement of the sample machine to be tested shall comply with the
requirements of 6.4 of GB/T 18801-2022;
e) Formaldehyde is preferably used as the target pollutant for the test; if the
formaldehyde removal capacity of the tested sample machine is not declared,
any one of the gaseous pollutants, for which the removal capacity is declared,
shall be used as the target pollutant.
The gaseous pollutant clean air delivery rate of air cleaners shall be tested under rated
conditions in accordance with the method specified in Appendix E of GB/T 18801-2022,
expressed as Qgaseous. When Qgaseous is ≥10 m3/h, the result is retained as an integer;
when Qgaseous is < 10 m3/h, the result is retained as one decimal place. When the sample
machine to be tested is a Category II product, the test shall be carried out in the air
purification function mode. If the sample machine to be tested has no rated state, the
highest wind speed gear is turned on by default for testing.
6.1.3 Input power of purification
The input power of purification is tested under the following test conditions in
accordance with the method specified in 7.6.1 of GB/T 18801-2022, represented by P,
and the result is rounded to one decimal place. The test conditions shall meet the
following requirements:
a) General test conditions shall meet the requirements of 6.1 of GB/T 18801-
2022;
b) The measuring instruments used for the test shall meet the requirements of 6.2
of GB/T 18801-2022;
c) When the input power of purification of the tested sample machine for
removing different target pollutants is different, it is expressed as Pparticulate and
Pgaseous, respectively.
