Differences between purifiers accumulating clean air volume in the purifier performance test chamber
----Dongguan Huanyi Instrument Technology Co., Ltd. Excerpted from GB18801
Many customers are not very clear about some conceptual things. The editor of Environmental Instruments is here today to bring it up for everyone to understand. Let you have a deeper understanding of the purifier performance test chamber.
1. Clean air volume
The actual measured value of the clean air volume of the purifier for particulate matter and gaseous pollutants should not be less than 90% of the nominal value.
2. Cumulative purification amount
The actual measured value of the purifier's cumulative purification volume for target pollutants should not be less than 90% of its nominal "cumulative purification volume". Moreover, the corresponding "cumulative purification volume" and the nominal "clean air volume" should be
3. Purification energy efficiency
The test value of the purification energy efficiency of the purifier in the purifier performance test chamber for particulate matter and gaseous pollutants shall not be less than 90% of its nominal value, and the purification energy efficiency for particulate matter shall not be less than 3.50 m3/(W·h), and for gaseous pollutants The pollutant purification energy efficiency shall not be less than 1.00 m3/(W·h).
4. Purification performance correlation compliance
The correlation between the CADR and CCM of the purification performance of the purifier for particulate matter and gaseous pollutants, as well as the noise and energy efficiency indicators should be in accordance with the table
