Technical requirements and test method of smart mode for air cleaner
1 Scope
This standard specifies the terms and definitions, technical requirements and test methods for the smart mode of air cleaner (hereinafter referred to as smart mode). This standard is applicable to electrical appliances with built-in air quality monitoring sensors and smart mode. For other products, this standard may apply by reference.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
GB/T 18801-2015 Air cleaner
GB/T 18883-2002 Indoor air quality standard
QB/T 5364-2019 Requirement and evaluation method of test chamber for air cleaner
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
smart mode
mode of completing actions such as perception, decision-making and execution by using air quality monitoring device built in the air cleaner according to the change of the concentration of pollutants in the surrounding environment
3.2
particulate matter (PM2.5)
particulate matter having an aerodynamic equivalent diameter of 2.5μm or less in the air
3.3
response time
in smart mode, the time required for appliances being adjusted from the minimum gear to other gears due to the increase of the pollutant concentration in the air
Note: The unit of minute (min) is adopted.
3.4
purification uniformity
U
difference between the maximum and the minimum concentrations of pollutants at all sampling points in the test chamber when appliances are adjusted from other gears to the minimum gear
Note: The unit of micrograms per cubic meter (μg/m3) is adopted.
3.5
maximum concentration
M
maximum concentration of pollutants at all sampling points in the test chamber when appliances are adjusted from other gears to the minimum gear
Note: The unit of micrograms per cubic meter (μg/m3) is adopted.
3.6
display accuracy
P
parameter used to evaluate the accuracy of the pollutant concentration displayed by appliances
Note: It is expressed as a percentage.
4 Technical requirements
4.1 Smart function
4.1.1 The appliances shall be able to indicate the indoor air quality in real time through indicator lights.
4.1.2 When the appliances detect that the filter element needs to be replaced, the filter element replacement indicator light shall be able to prompt each time the appliance is turned on.
4.1.3 The appliances shall be able to realize the smart functions indicated in the product instructions and on the product packaging.
4.2 Response time
The response time of appliances shall not exceed 30min.
4.3 Class of purification uniformity and maximum concentration
