A window-opening test chamber of an air purifier and its test method

Abstract

The invention discloses a window-opening experiment testing cabin of an air purifier and a test method of the window-opening experiment testing cabin. The window-opening experiment testing cabin mainly comprises an outer cabin and an inner cabin, wherein a detector and a window are arranged in the inner cabin; a monitoring device is arranged between the inner cabin and the outer cabin; the window-opening experiment testing cabin further comprises a contaminant generator; actual and reliable experimental data is provided, and the temperature, humidity and environment contaminant are set to simulate the actual situation as much as possible and achieve high matching degree. The window-opening experiment testing cabin disclosed by the invention carries out a dynamic testing method to ensure the reliability of the detection data, restore the actual using effect of the air purifier to the maximum, bring convenience to consumers to identify and purchase the air purifier, and improve the living quality of the consumers.

Description

technical field [0001] The invention relates to the field of purifiers, in particular to a window-opening test chamber of an air purifier and a testing method thereof. Background technique [0002] Environmental protection work lags behind industrial development, and the pollution in the atmospheric environment is becoming more and more serious, including particulate matter pollution (such as PM2.5) mainly from industrial waste gas and vehicle exhaust, and gas pollution (such as formaldehyde , benzene, etc.). In order to pursue a higher quality of life, people have more and more demand for air purifiers, and their performance requirements are also getting higher and higher. There are many types of air purifiers on the market, with different brands and prices ranging from a few hundred yuan to tens of thousands of yuan. Manufacturers claim that their products have excellent air purification effects, but consumers have difficulties in choosing them. [0003] Usually, the fac...

AI Technical Summary

Problems solved by technology

[0005] (1) Use airtight conditions for repeated operation, no external pollutants to supplement (infiltration of polluted atmosphere into the room), the detected pollutant removal rate is detected after long-term adsorption, which is somewhat misleading for consumers

[0006] (2) The airtight conditions do not match the conditions that consumers actually use the air purifier: the real room cannot be completely sealed; especially when the elderly or children use it at home, they usually open some windows for ventilation (a common habit of opening windows in southern China), In order to avoid the lack of oxygen in the indoor air caused by closing the windows for a long time, it will affect human health

However, the air purifier tested under the condition of opening the window may not be able to achieve the claimed effect at all.

[0007] (3) The air purifier detected by the existing detection method claims to have a purification efficiency of more than 99%, a series of parameters such as CADR value are difficult for consumers to understand, and it is impossible to intuitively judge whether the performance of the air purifier is good or not OK, is it suitable for my own use?

[0008] (4) Existing detection methods cannot test the lifespan of the filter used to remove PM2.5 and formaldehyde, and it is very easy for the overused filter to become a secondary pollution source, leading to more serious air pollution

[0009] (5) Existing detection methods do not use precise temperature and humidity control devices to control the test air chamber, and do not consider the difference in volatilization and adsorption of harmful gases such as formaldehyde without precise temperature and humidity control
