Cleaner than Nordic air? The filtration efficiency of Volvo's new technology PM2.5 is as high as 95%.

[car home? Industry] Recently, the invention patent of key in-vehicle technology of AAC double-effect enhanced air purification system of Volvo Cars (hereinafter referred to as AAC) was approved in the United States. The invention patent relates to the installation technology of vehicle-mounted air purification system, which is applied globally by Volvo Cars in China, the United States, the European Union and other countries and regions.

The air purifier used at home on weekdays can enhance the filtering effect by ionizing air particles, but the air velocity in the car is 50 times that of the ordinary indoor environment, and the temperature and humidity are quite different, so the installation position is limited. The integrated AAC introduced by Volvo Cars can effectively solve these problems.

Specifically, installing AAC near the water-gas separator can ensure the air filtration effect by changing the air flow direction, which can make the environmental application conditions more harsh, and at the same time, the purification system can have the same product life cycle as the automobile. In addition, AAC is equipped with a composite activated carbon air conditioning filter specially built by Volvo Cars for the China market, which can ensure the filtering effect of PM2.5.

Compared with the common household air purification equipment with large volume and weight of about 15 kg, AAC weighs only 400 grams, and its shape is completely designed as a flat carrier with circular holes. In addition to redesigning the material, weight, volume and size of air purification equipment according to vehicle standards and requirements, R&D personnel should also find the best installation location for it and verify the system. This is also one of the key contents of Volvo Car's patent application for this invention.

In the verification of air purification system, Volvo Cars can verify the air purification system under different humidity and temperature conditions, even in the ice and snow environment. It uses 10 nanometer professional air testing equipment, and adopts enterprise-level standards stricter than international standards to test the working effect of the air purification system to ensure the working effect of the air purification system.

It is reported that AAC has a good filtration effect on fine particles of 1 micron, and the filtration efficiency of PM2.5 particles is as high as 95%. The system will be first installed on S60 and S90 vehicles in 2020 and beyond. (Text/car home? Peng Fei)
