●? 30 seconds to quickly understand Roewe iMAX8 active health cockpit
Roewe iMAX8 cockpit has good air tightness, and the internal air pressure is about 20-60Pa higher than that outside after air conditioning is turned on.
The negative ion generator and high-efficiency air conditioning filter element are integrated in the air conditioning system, which can purify the air while turning on the air conditioner.
AVTECH filter element adopts three-layer structure, which has better adsorption and inhibition effect on germs and tiny particles.

SAIC has rich experience in indoor air quality management. Even in March of this year, I experienced Roewe RX5? MAX's active health cockpit system (click here for details) has equipment with high filtration effect, such as air conditioning filter element, deep ultraviolet disinfection lamp, vehicle negative ion generator and so on. Roewe iMAX8 is also equipped with high-efficiency air conditioning filter element and negative ion generator, but both integrated and filtering performance have been improved to some extent.
From 20 13, SAIC began to develop independent air filtration equipment in response to people's concerns about smog. Among the existing Roewe models, including Roewe RX5? MAX, Marvel Comics? X and other models are equipped with independent air purification devices. Roewe iMAX8 integrates all purification devices into the air conditioning system. The car is equipped with two air conditioning systems. The front air conditioner provides internal/external circulation, with built-in purification equipment, negative ion generator and AVTECH filter. The rear air conditioner has only one internal circulation, with AVTECH filter as standard.
SAIC built Roewe iMAX8 cockpit into a positive pressure cockpit. Due to the good air tightness of the whole cockpit, the air volume was adjusted to the third gear after all the windows were closed and the air conditioner was turned on. At this time, the air pressure in the cockpit is slightly higher than that outside, and the pressure difference between inside and outside is about 20Pa. When the air volume is adjusted to the maximum, the pressure difference between inside and outside can reach 50-60Pa (a standard atmospheric pressure value is1.01325×10, and the difference of several tens of Pa is almost imperceptible in the sense of the body). Maintaining a certain pressure difference is helpful to prevent unfiltered air from entering the car through a small gap and affecting the health of passengers.
In order to achieve better indoor purification effect, the most commonly used method at present is to replace the air conditioning filter, and SAIC models are no exception. SAIC cooperated with several filter suppliers to launch two products, namely activated carbon filter and PM2.5 high efficiency filter. AVTECH air conditioning filter used in Roewe iMAX8 has been increased from two-layer structure of PM2.5 filter to three-layer, and meltblown cloth with electrostatic adsorption function has been added, so the filtering and bacteriostatic effects have reached a new height.
According to the official introduction, AVTECH fabric was developed under the leadership of Academician China Academy of Engineering, Deputy Director of Eco-environmental Research Center of Chinese Academy of Sciences, and Academician Stanley, a scientist from Ding Sheng. Tested by P3 laboratory of Shandong Center for Disease Control and Prevention, the fabric has the function of adsorbing and removing novel coronavirus (novel coronavirus). At the same time, it is certified by CMA/CNAS certification laboratory, and it is effective against other infectious viruses (such as H 1N 1/H3).
In order to verify the filtering effect of the filter element, we did a field experiment, stuffed a Roewe iMAX8 into a closed space full of smoke, and then turned on the air conditioner in the car to see if the vehicle could really achieve the purification effect. First, we made smoke in the cabin for experiments. After a round of testing, if the front and rear air conditioners are all turned on and the air volume is adjusted to the maximum, it will take about 3 minutes for the PM2.5 concentration to drop from 500 to less than 20. Then we filled the whole tent with smoke to test, and the air conditioning system can also achieve excellent filtration and purification effect.

●? The article concludes:
The excellent cockpit environment of Roewe iMAX8 mainly depends on the air conditioning system. The built-in negative ion generator and AVTECH filter element in dual air conditioning system are the most important equipment to deal with external pollutants. It can be seen from field experiments and third-party reports that these two parts really play a vital role in improving the air quality inside the car and ensuring the health of passengers. In the complex external environment, having such a reassuring cockpit really gives users more protection. (text/picture/photo? Car home? Zhu)
