Minimum Allowable Values of Energy Efficiency and Energy Efficiency Grades for Air Cleaners
1 Scope
This standard specifies minimum allowable values of energy efficiency and energy efficiency grades for air cleaners as well as their test and calculation methods.
This standard is applicable to air cleaners with rated voltage not greater than 250 V and certain purifying capacity of particles (clean air delivery rate of particles is 50 m3/h~800 m3/h).
This standard is not applicable to:
——air cleaner adopting ion generating technology only;
——airway-type air cleaning unit and other similar air cleaners;
——air cleaner having purifying capacity of gaseous pollutants and microorganisms;
——air cleaner specially designed for industrial use, medical use and vehicles;
——air cleaner used in special environment with corrosive and explosive gas (e.g., dust, vapor and methane gas).

3 Terms and Definitions
For the purposes of this document, the following terms and definitions apply.
3.1
rated condition
the working state of the air cleaner corresponding to the cleaner's nominal purifying capacity
3.2
clean air delivery rate of particle; CADR
the parameter in terms of purifying capacity of particles for air cleaners under rated condition and specified test condition; which shows the provision rate of clean air in terms of particles by air cleaner
3.3
input power of purify
the required input power for air cleaner providing clean air delivery rate of particle under rated condition
Note 1: Including the input power of electrical components uncapable of being turned off individually such as motor, high-voltage electrostatic generator, ion generator, control and drive circuits.
Note 2: Excluding other separable functions of air cleaner; only the consumed input power required for realizing purifying capacity of particles is considered.
3.4
energy efficiency ratio; EER
the ratio of CADR to input power of purify provided by the air cleaner under rated condition
3.5
standby power
the input power of the air cleaner under state that the cleaner is connected to the power supply to provide instruction waiting (including restart) with information or status display (including clock), communication protocol and other functions simultaneously but without any function for contaminants purification
Note: Restart is a kind of function to switch the air cleaner to mode of providing contaminants purification by remote controller, internal sensor or timer and other means.
3.6
purification efficiency of gaseous pollutants
the parameter of the air cleaner in terms of purifying capacity for gaseous pollutants under rated condition and specified test conditions and after operation in estimated equivalent testing time, which shows the purification efficiency on gaseous pollutants of air cleaner after 1 h operation under working condition of nominal applicable area
3.7
minimum allowable values of energy efficiency
the minimum allowable value of energy efficiency ratio and the maximum value of standby power for the air cleaner under rated condition and specified test conditions
4 Energy Efficiency Grades
Energy efficiencies of air cleaner are divided into three grades (see Table 1), among which Grade 1 is the highest. The energy efficiency ratio and standby power of all-grade products shall meet the requirements of Table 1.
Table 1 Indexes of Energy Efficiency Grade
Energy efficiency grade Energy efficiency ratio, m3/(W·h) Standby power, W
Category I Category II
1 EER≥13.00 EER≥11.00 ≤1.0 (only instruction waiting is provided) ≤2.0 (including other functions)
2 10.00≤EER<13.00 8.00≤EER<11.00
3 3.50≤EER<10.00 3.50≤EER<8.00
Note: Category I products refer to the air cleaner which is declared to only have purifying capacity of particles or whose measured purification efficiency of any kind of gaseous pollutant that is declared by the cleaner to have purifying capacity is less than 50%; Category II products refer to the air cleaner which is declared to have purifying capacity of particles and gaseous pollutants or whose measured purification efficiency of each kind of gaseous pollutant that is declared by the cleaner to have purifying capacity is not less than 50%.
