How to choose a fresh air system 5

Sharing cases from fresh air system users:

Shijiazhuang Ms. Wang:

The house is finely decorated, when buying a house, the developer said that there is a fresh air system, very expected, after all, the air in Shijiazhuang is really poor, especially in autumn and winter most of the time is haze weather, look at it on the heart, there is a fresh air system, a little comfort.

The developer said that it was a brand of one-way flow from Bailang, and it was difficult to explain the specific use. Not to mention the effect, just after opening it, the rumbling noise gave me a slap in the face. Then after half a year, I went to change the filter by myself, and found that there was only a very thin layer inside, and there was nothing after that, so can it prevent haze?

Comments: Ms. Wang's situation is very representative, the fresh air system used by real estate companies is generally one-way flow, the reason is very simple - in order to control costs. Whether it is useful or not, let's take a look at the configuration of the one-way flow fresh air system:

Generally, it is an AC fan, which does not have a full heat exchange core, and only intakes air. Let's put it this way, compared with the new fan with two-way flow full heat exchange, one in the sky and the other in the place.

Xi'an Aunt Xing:

Xi'an is also a city with frequent smog. When the second house in the family was renovated, I thought about installing a fresh air system. I have been to the store and think it is very expensive, and then I looked around and found that there is a dust-free brand that sells very cheaply, two or three thousand yuan, and it is also two-way flow, with a filter element and full heat exchange, it feels very worthwhile, but it is not included in the installation, I thought there was nothing to do, just find someone to install it yourself.

As a result, from the moment I received the goods, I began to regret it. First of all, the machine is not very good-looking, and the filter element and full heat exchanger are small. Then it is not to package the installation, to find someone to install, the result back and forth things toss not to say, the installation also cost more than three thousand, and the middle and the family a few times awkward, and finally the noise after the installation is to make me completely regret, persuade friends who want to install fresh air must not choose a bargain.

Comments: Generally speaking, you get what you pay for, especially for new fans less than three thousand, you must consider carefully. It is also recommended to buy a new fan for package installation, because the installation of fresh air is a very professional work, which needs to be done by a special person, not just to install the fresh air duct, but also to consider noise and air volume.

Recommendation:Finally,To sum up,The best way to buy fresh air is to make a comprehensive comparison on Tmall Jingdong,Be sure to choose a two-way flow EC fan,Physical filter with full heat exchange of new fans,It is best to install it in a package,**Between 80000-12000,You can already buy very good products!

The main aspects of fresh air selection are these.

1 to see their own needs, the area of the room corresponds to the air volume, the general room area multiplied by three equals the air volume 2 test the actual effect of the new fan, generally use the haze meter to detect the air quality 3 to see the filter element, several layers of filtration, filter element level.

4. There is no heat exchange or electric auxiliary heat.

5. Find a professional team to design and install
