[Aika car shopping guide original]
I did not expect that in this beautiful month when spring is in full bloom and should have gone out to play, the epidemic will fight back again and be menacing. Coupled with the increase in the concentration of pollen, many allergy patients feel sad. As an important tool for travel now, many car manufacturers have also begun to wear "N95 masks" for their cars, isolating viruses, pollen and pollutants, and also allowing you who have worn masks for a long time to breathe. Today, I will introduce you to several cars with PM2.5 filtering function to make your travel more secure.
Let's first take a look at the current mainstream air purification in the car. At present, there are three kinds of mainstream in-vehicle air purification on the market, namely filter filter, negative ion generator purification and in-vehicle air quality monitoring and cleaning system. How do they all work?
●Filter element filtration
First of all, let's talk about the simplest way - air conditioning filter filter. The car air conditioning system has two channels, one is the most commonly used internal circulation, and the other is the external circulation. The air purification in the car can be said to be 100% dependent on the internal circulation mode, in which the air outside the car needs to pass through the air conditioning filter. Therefore, in order to make the car have the ability to filter PM2.5, it is only necessary to replace the air conditioning filter element with a higher filtration level. To put it bluntly, it is to wear an N95 mask for the car.
Like the protection level of the mask, the air conditioning filter is also graded, and the rating of it is HEPA level. Among them, the filter element above the E11 level can filter particles with a diameter of 300 nm, and the filtration effect has reached more than 95%, and the effect is similar to that of N95 masks. Therefore, in theory, the filter element with HEPA level above E11 can block pollutants, pollen, viruses, etc. from entering the car, but just like our N95 masks, the filter element also needs to be replaced in time, otherwise it will fail. The price of this kind of air conditioning filter is not very high, according to different models, the price is generally around 100 yuan-200 yuan, compared to the ordinary air conditioning filter element is also more expensive than twenty or thirty yuan, and will not increase too much car cost.
Seeing this, someone must have opened a certain east and a treasure ready to place an order. But don't worry, the air conditioning filter with high filtration grade can indeed keep pollutants out of the car, but! The vehicle's air circulation system, in order to prevent the internal circulation time from causing the internal circulation time to cause poisoning of members with too high carbon dioxide concentration in the car, specially designed a "protective BUG", that is, the switch control mechanism of the internal and external circulation reserved a gap, which is the same as wearing a mask afraid of boredom on the mask to open a few small holes. Therefore, the air conditioning filter can only filter and block a part of the pollutants, really want to completely block that may have to be the tank's anti-biochemical level.
●Negative ion generator purification
Since there is no way to completely block bacteria, viruses, pollen, pollutants, etc. from the outside of the car by relying on the filter element, is there any way to sterilize the air inside the car? Don't say, there really is! That's what I'm going to cover next – negative ion generator purification.
Compared with the simple and crude air conditioning filter filter, the purification of the negative ion generator is much more complicated. Plasma is generated through high-voltage circuits, and negative ions are used to destroy the protein membrane on the surface of bacteria, thus killing bacteria and molds in the air. At the same time, negative ions can also adsorb particulate matter and accumulate sedimentation, thereby further reducing the content of respirable particulate matter in the air in the car, and the plasma generator can also partially decompose styrene and other gases, playing a role in purifying the air.
At present, the negative ion generator purification system in the car is mainly composed of three parts: the negative ion generator, the micro fan and the filter. The working principle is relatively simple, through the micro fan to accelerate the air flow in the car, air flows through the negative ion generator to generate a large number of negative ions, the formation of negative ion gas flow, with particulate matter, virus after the settlement of negative ions with the air flow through the filter, and is filtered adsorbed. The cycle repeats to achieve the purpose of purifying the air in the car. Negative ions can not only quickly neutralize the particles (including second-hand smoke and oil smoke) that are positive ions in the air, but also kill the bacteria and mold in the car and completely clean the air in the car. At the same time, the appropriate amount of negative ions in the air can also promote the synthesis of some vitamins in the human body, strengthen the physiological functions of the human body, and make people feel physical and mental pleasure in the car.
●In-car air quality monitoring cleaning system
If filter filter filtration is the basic and negative ion purification is advanced, then the air quality monitoring and cleaning system in the car is the ultimate version. It not only has a high filtration level filter element and in-car air purification equipment, but also equipped with AQS system (full name Air Quality System automotive air quality control system).
AQS system can monitor the air quality outside the car in real time, when the air quality outside the car is poor, the AQS system will automatically close the external circulation of the car, turn into an internal circulation, and the poor external air is difficult to directly enter the car; when the air quality outside the car is better, the AQS system will automatically open the external circulation and let fresh air enter the car.
The AQS system not only automatically adjusts the internal/external circulation of the air conditioner according to the air quality outside the car, but also controls the air purification equipment in the car. When the internal circulation is opened because of the poor air quality outside the car, the air purification equipment and negative ion generator in the car will be opened, and the air in the car will be filtered and purified, and finally become clean air circulating in the car.
Mainstream car interior air purification you know a few
After a brief understanding of the three more mainstream air purification methods in the car on the market, let's take a look at what are the representative models of various purification methods. Let's start with the most basic filter element filtration.
●Filter element filtration
◆ Representative model: SAIC-GM Buick Weilang - nano-level anti-PM2.5 air conditioning filter
Compared with the once slightly mature style, the new Veyron is currently on sale a lot younger. The front of the car still features Buick's classic flying wing grille, and the narrow LED headlights on both sides are cleverly integrated. The simple and smooth side lines of the body make it look sporty. The rear of the car looks more solid, the taillight position is higher, the bumper is also relatively thick, and the overall visual center is very high, but the lower encirclement adopts a slightly upward treatment, which makes the rear of the car also have an upward posture.
