Regarding automotive air conditioning, let's talk about the internal and
external circulation. I haven't heard of air entering the car through the air conditioner without passing through the filter for two years. As a China Air
Filter Element Manufacturer, I will share it with you.
Plate Type Filter
If you add filtration element, don't get too tangled, just tell you, no matter the inner circulation, outer circulation, the air will eventually pass through the filter core. (The premise is that the blower must be running to provide the premise of airflow.) However, if the filter element is added, then the position can be in two of them. Install the filter element before the evaporator.
Regarding the role of the Filter Element, this thing is, alas, fish and bear paws are both inaccessible. The filtration performance and ventilation performance can only find a balance, not both. And, this thing is a common cover, the ability to adsorb pm2.5 is simply, Um, dozens of things, the design did not consider pm2.5 at all, what do you expect him to do. Some dust is properly filtered, but please keep in mind that this thing is not expensive. The frequency of air conditioning is high, it is not an exaggeration to change it once a month, but it is not necessary to buy a dozen for 4s each time, and change it every one or two months. There is a problem.
Don’t think about it, just cycle inside. The air in the car is not good, the family travels in the mountains, and the two smokers in the car.
Ok, the weather is cool and the window is opened directly. If it is too cold or too hot, please adjust the air volume of the air conditioner to be higher and cycle to the outer cycle. However, the effect is limited.
Circulate for a long time, the air in the car is not fresh, and circulate for a long time outside, you also need to consider that the air environment outside the car is good. Once there was a call before, the driver master pressed the car to press the inner cycle. It closed the window.
To add a small point, automotive air conditioning is also constantly improving. Some cars have a certain strategy for internal and external circulation during automatic circulation. Generally, internal circulation is still pure internal circulation, but external circulation may not be completely external circulation. At the time, the inner circulation damper and the outer circulation damper both have a little opening.
