Regarding automobile air conditioners, let's talk about internal and external circulation. After two years in the business, I haven't heard of air entering the car through the air conditioner without filtering. As a V Type Combined Filter Supplier, share it with you.
V Type Combined Filter
If you add a filter element, it is at the position of the pink and white strips, the schematic diagram, do not tangle too much, it is to tell you that no matter the internal circulation, external circulation, the air will eventually pass through the filter element. But if you add a filter, then two positions can be located, a friend said, install the filter before the evaporator.
Regarding the role of the filter element, this thing is not available, fish and bear's paw. Filtering performance and ventilation performance can only be balanced, not both. Moreover, this thing is an ordinary cover, the ability to absorb PM2.5 is simply Well, dozens of pieces, the design did not consider pm2.5 at all, what do you expect him to do? Larger dust is properly filtered, but please remember that this thing is not expensive If the air conditioner is used frequently, changing it once a month is not an exaggeration, but you don't have to buy a dozen by yourself every 4s and change it every month or two. It is simple and fast to improve the air quality in the car. That is a problem.
Let's just circulate. (Trial scenario, traffic jam conditions, driving in areas with severe chemical pollution, coal mines, etc., you can make up your own mind) The air in the car is a bit rough, the family is enjoying the mountains and the water, and two smoke guns in the car. Well, the weather is cool and the window is opened directly. It is too cold and hot. Please adjust the air volume of the air conditioner to be higher and cycle to the outer cycle. However, the effect is limited.
Circulation for a long time, the air inside the car is not fresh, and the external air environment for a long time needs to be considered. The air environment outside the car has to be considered good. Once I hit it once, the driver master pressed the car to circulate inside. It really is an old driver, I take it. But you Close the window.
Adding a little point, automobile air conditioners are also constantly improving. Some cars have a certain strategy for internal and external circulation during automatic cycling. Generally, the internal circulation is still purely internal, but the external circulation may not be completely external. When the internal circulation damper and the external circulation damper are slightly open, this can improve the efficiency of air conditioning cooling or heating to a certain extent.
Why does the air volume of the air filter become smaller? I believe that many customers have some doubts about this problem during the use of the product. Today we will explain to you the reasons for the small air volume of the Metal Filter Cartridge.
First: First confirm whether the final resistance of the Metal Filter Cartridge (that is, the value it reports) has reached the final resistance during use. Generally, the final resistance value of the air filter is 400-600pa.
Two: Metal Filter Cartridge front-end primary effect filter, whether the medium-efficiency filter has reached the final resistance value, because of the initial effect, the intermediate effect mainly plays a role in protecting the air filter. If the front-end primary effect medium-efficiency filter reaches. The destruction value also affects the air volume of the air filter.
3: Is the air volume of the air-conditioning unit in the process of use or not the air volume required for the entire purification space?
