Test procedure for the cumulative purification amount of gaseous pollutants in the 30 cubic meter cumulative formaldehyde removal performance test chamber
Test steps of 30 cubic meter cumulative formaldehyde removal performance test chamber
Follow the steps below to carry out the cumulative purification amount test of formaldehyde:
3.1. In accordance with the provisions of Appendix B, the initial value of the formaldehyde clean air volume of the purifier is tested, evaluated and recorded;
3.2. 30 cubic meter cumulative formaldehyde removal performance test chamber After that, put the purifier into the 10m3 test chamber, turn on the purifier, and adjust it to the rated state; turn on the stirring fan and close the test chamber door;
3.3. According to D.2 formaldehyde generation conditions, the continuous injection method is used to load formaldehyde gas into the 10m" test chamber. When the continuous injection method is used to load formaldehyde, the loading rate is 20 mg/h;
3.4. 30 cubic meter cumulative formaldehyde removal performance test chamber After confirming that the measured injection volume after continuous loading reaches the injection volume specified in step e), continue to run for 1 h, measure the formaldehyde concentration in the test chamber, and take the total injection volume minus the stable remaining formaldehyde volume in the test chamber as The actual removal amount this time, then turn off the purifier, and let it stand for 16h in the laboratory environment. After that, put the purifier into the 30 m3 test chamber again, and conduct a formaldehyde clean air volume test in accordance with Appendix B and record;
3.5. Repeat steps b) to d) to obtain the clean air volume when the cumulative injection volume is greater than 300 mg, 600 mg, 1000 mg, and 1500 mg. When the measured clean air volume is less than or equal to 50% of the initial value, the test ends ;
The sum of the actual removal volume of each loading test of the 3.6.30 cubic meter of cumulative formaldehyde removal performance test chamber and the removal volume of each CADR test is recorded as the total cumulative removal volume of the purifier, and the interval of the measured cumulative purification volume is calibrated Binning.
The above information is shared here. In addition, the 3 cubic meters and 30 cubic meters air purifier environmental test chambers developed and produced by our company have accurate temperature and humidity control, good air tightness, and low background concentration of the cabin, which can not only test and research air purification products.30 cubic meter cumulative formaldehyde removal performance test chamber It can also test the pollutant emission of building decoration materials and some home appliances.
