Background
The work of environmental protection lags behind industrial development, and pollution in the atmospheric environment is becoming more serious, including particulate pollution (such as PM2.5) mainly derived from industrial exhaust gas and vehicle exhaust gas, and gas pollution (such as formaldehyde, benzene, etc.) derived from poor finishing materials. In order to pursue higher quality of life, the demand for an air purifier, an electric appliance, is increasing, and the performance requirements for the air purifier are also increasing. Air purifiers on the market are various in types and brands, the price is from hundreds of yuan to tens of thousands of yuan, manufacturers claim that own products have excellent air purification effect, and consumers have difficulty in selecting the air purifiers.
The conventional delivery inspection method of the air purifier is carried out in a reaction chamber with a fixed volume and good sealing performance, and the air purifier repeatedly runs in the chamber for a period of time by injecting pollutants with certain concentration to inspect the concentration of the residual pollutants in the chamber, belonging to a static test method.
The following problems exist in the conventional performance detection method of the air purifier:
(1) the operation is repeated under a closed condition, no external pollutants are supplemented (the polluted atmosphere permeates into the room), the removal rate of the detected pollutants is detected after the pollutants are adsorbed for a long time, and certain misleading is provided for consumers.
(2) The containment conditions are not in accordance with the conditions under which the consumer actually uses the air purifier: a real room cannot be completely sealed; especially, when the old or the children use the window at home, a part of the window is usually opened for ventilation (common window opening habit in southern China), so as to avoid that the oxygen in the indoor air is insufficient and the human health is influenced due to long-time window closing. And the air purifier inspected under the condition of windowing can not completely achieve the alleged use effect.
(3) The air purifier detected by the existing detection method claims that a series of parameters such as purification efficiency and CADR value of more than 99 percent are difficult to understand for consumers, and the usability of the air purifier cannot be intuitively judged to be poor, so that the air purifier is not suitable for being used by the consumers.
(4) The service life of a filter screen used for removing PM2.5 and formaldehyde cannot be tested by the conventional detection method, and the filter screen which is excessively used is very easy to become a secondary pollution source, so that more serious air pollution is caused.
(5) The existing detection method does not use a viscosity temperature and humidity control device to control the test air chamber, and does not consider the volatilization and adsorption effect difference of harmful gases such as formaldehyde and the like under the condition of no accurate temperature and humidity control.
At present common solution adopts the mode that the formula of windowing simulation detected, adopts artifical supplementary pollution sources to guarantee that the pollution sources keeps the mean value in the experimental environment, and the problem of this scheme lies in only can keeping the interior pollutant concentration mean value of experimental environment, the inhomogeneous condition of pollutant among the unable simulation natural environment, and outside, because air-blast system also is in test environment, consequently can't carry out humidity simulation test to avoid interior equipment air-blast equipment to be contaminated, so can't simulate the haze polluted environment of high humidity.
