Air purifier testing equipment

Air purifier testing equipmentThis test bench is mainly used to simulate and detect the pollutant removal test of air purifiers.

This test bench mainly consists of a laboratory, clean air inlet, exhaust system, and sampling devicecompose.

The natural attenuation test is as follows:

1) Place the air purifier to be tested on the test bench in the middle of the laboratory (except for vertical air purifiers), adjust the air purifier to the working state, check if it is running normally, and then turn off the air purifier;

2) Arrange the sampling points in a position that avoids the air inlet and outlet, with a distance of 0.5m from the wall and a relative height of 0.5-1.5m above the laboratory floor. One or more sampling heads can be installed at the same sampling point and connected to external sampling tubes;

Close the exhaust duct air valve, open the internal circulation duct air valve, start the auxiliary fan, and use a high-efficiency filter to purify the air in the laboratory, so that the particle diameter is Above 0.3 μ m

3)The particle background concentration is less than one thousandth of the initial detection concentration, while detecting the air temperature and humidity in the laboratory;

4) Wait for the background concentration of particulate matter to decrease to an appropriate level, record the current background concentration of particulate matter, turn off the circulating fan and high-efficiency filter, start the household ceiling fan, and use the sampling device to place the smoke pollutant in the laboratory and allow it to enter the air vortex generated by the ceiling fan stirring. Stir for 10 minutes, and then turn off the household ceiling fan after the pollutants are mixed evenly;
