The present invention discloses a testing system and an analysis method for the vehicle-mounted exterior circulation type air purifier micro-particle number concentration purification efficiency. The apparatus mainly comprises a smoke generator, a smoke generation box, an air conditioner, a mixed fan, an environment temperature, humidity and pressure tester, an air purifier, a connection pipeline 1, a valve, a connection pipeline 2, a flow rate regulation valve, a vacuum pump, and two sets of particle particle-size spectrum testers. According to the method, under a rated flow rate, the number concentrations and the particle size spectrums of particles entering and leaving both ends of the air purifier are tested, and the purification efficiency of the particles having different particle sizes is calculated through the purification efficiency formula. According to the present invention, the testing system is clear and complete, the calculation and analysis method is correct and reasonable, and the system and the method can be used for the quantitative determination of the vehicle-mounted exterior circulation type air purifier micro-particle number concentration purification efficiency.
Description
technical field [0001] The invention relates to an air pollutant purification efficiency test device and method, in particular to a test system and analysis method for the purification efficiency of the particle number concentration of a vehicle-mounted air purifier. Background technique [0002] With the acceleration of industrialization and urbanization in our country, road air pollution is becoming more and more serious, becoming an invisible killer that affects the health of people traveling in traffic. 68% of human diseases are related to air pollution, and the World Health Organization lists indoor air pollution as the first of 18 types of carcinogens. Of the 20 most polluted cities in the world, 16 are in China. With the enhancement of people's environmental awareness and the improvement of living standards, they are increasingly aware of the importance of clean air to personal health. [0003] At present, in my country, aerosol particle pollution is the primary pol...
