------Huanyi Industry (Hong Kong) Limited extracted from GB18801

Product name: Purifier CADR Test Chamber, Purifier CCM Test Chamber, Purifier Clean Air Volume Test Chamber

Concept introduction：

1. Natural attenuation

In the specified space and conditions, due to non-human factors such as sedimentation, agglomeration, surface deposition, chemical reaction and air exchange, the concentration of target pollutants in the air is reduced.

2. Total attenuation

Under the specified space and conditions, due to the combined effect of natural attenuation and purifier purification operation, the concentration of target pollutants in the air is reduced.

3. CADR of clean air

The parameter of the purifier's ability to purify target pollutants (particulate matter and gaseous pollutants) under the rated state and specified test conditions; it represents the rate at which the purifier provides clean air.

Note 1: The unit is cubic meter per hour (m3/h).

Note 2: The air duct type purification device does not use this indicator.

4. Cumulative purification amount CCM

The parameter of the cumulative purification capacity of the purifier under the rated state and the specified test conditions for the target pollutants (particulate matter and gaseous pollutants); when the clean air volume of the purifier decays to 50% of the initial value, the cumulative pollution treatment target pollution The total mass.

Note: The unit is milligram (mg)

5. Purification of energy efficiency

The amount of clean air produced by the unit power consumption of the purifier in the rated state.

6. Applicable area

The purifier is based on the CADR value indicated by the purifier under the specified conditions, and is derived by the algorithm specified in Appendix F. The (maximum) room area that can meet the purification requirements for particulate matter, gaseous pollutants, etc. Note: Unit Is square meter (m²)

7. Purification life

Take the ratio of the cumulative purification volume for the target pollutants marked by the purifier to the calculated daily average treatment volume corresponding to the purifier as a reference, expressed in (days).
