The Research About Improvement Of Portable Air Purifier Performance And Test Methods

People now have more than 70% of the time spent indoors,so the quality of indoor environment can directly affect human health.As a convenient installation,simple use and relatively low price of air purifier purification equipment has been more and more families choose to use.Research shows that China's air quality ranks fourth from the bottom in the world,and the market sales of air purifiers have exceeded 350 million yuan in 2017.With the improvement of people's quality of life,more and more people are concerned about their health and choose to use air purifiers.At the same time,in the context of increasing energy shortage and rapid economic development,it is necessary to ensure the purification effect while reducing energy consumption on the basis of saving energy as much as possible.Through practical testing and theoretical analysis,we can also know that there is still room for improvement and optimization in the current testing process.In this paper,the particulate matter performance of air purifier was detected by the national standard test method,and Suggestions on the improvement of air purifier performance,test process and test method were put forward.The particle performance of different types of air purifiers was tested,the performance of filters was tested,and the inlet and outlet optimization of air purifiers was compared.Is given on the basis of the existing optimized the design of the air purifier,in the same conditions,the best purifying effect,puts forward testing instrument used by the diluter shall not be higher than the 5.5 times,at the same time,the range of testing instruments shall not be less than 3.6 x105 a/L,and for big air volume air purifier should choose a big size test tank,can improve detection accuracy.Specific additional functions were tested to investigate their effects on clean air volume(CADR).At the same time,the market research on the current air purifier market was carried out,Suggestions on the sales of domestic air purifiers were put forward,and the analysis and prediction of the Chinese market were made.
