How to see the natural attenuation of the purifier environmental test chamber----Dongguan Huanyi Instrument Technology Co., Ltd. Excerpted from GB18801
Product name: Purifier CADR experimental cabin, purifier CCM experimental cabin, purifier clean air volume test cabin
Manufacturer: Dongguan Huanyi Instrument Technology Co., Ltd.
Introduction to concept values
1. Natural attenuation
Under specified spaces and conditions, the concentration of target pollutants in the air is reduced due to non-human factors such as sedimentation, agglomeration, surface deposition, chemical reactions, and air exchange.
2. Total attenuation
Under the specified space and conditions, due to the combined effect of natural attenuation and purification operation of the purifier, the concentration of target pollutants in the air is reduced.
3. Clean air volume CADR
Parameters of the purification capacity of the purifier for target pollutants (particulate matter and gaseous pollutants) under rated conditions and specified test conditions; indicates the rate at which the purifier provides clean air.
Note 1: The unit is cubic meters per hour (m3/h).
Note 2: This indicator is not used for air duct purification devices.
4. Cumulative purification volume CCM
Parameters of the cumulative purification capacity of the purifier for target pollutants (particulate matter and gaseous pollutants) under rated conditions and specified test conditions; indicates the target pollution of the cumulative purification process when the clean air volume of the purifier attenuates to 50% of the initial value. total mass of matter.
Note: The unit is milligram (mg).
5. Purification energy efficiency
The amount of clean air produced by the purifier per unit power consumption under rated conditions.
6. Applicable area
Under the specified conditions, based on the CADR value stated on the purifier and deduced by the algorithm specified in Appendix F, the (maximum) living room area that the purifier can meet the purification requirements for particulate matter, gaseous pollutants, etc. Note: Unit is square meters (m²).
7. Purification life
The ratio of the cumulative purification capacity of the target pollutants marked on the purifier to the calculated average daily processing capacity of the purifier is used as a reference, expressed in (days).
