When modern homes are renovated, they will consider the indoor air quality and naturally consider the fresh air system. So when choosing a fresh air system, which one should many brands choose? In fact, in addition to choosing a brand, it is more important to look at the following properties:

See function. Different models have different functions. For example, new fans equipped with HEPA high-efficiency filters are mainly equipped with anti-haze purification function; equipped with a full heat exchange core can realize pre-cooling and pre-heating during indoor and outdoor air replacement, reducing indoor heat loss to achieve energy saving. The filter of the fresh air system determines its filtering effect. Pay attention to the specific filter filtering level when selecting.

Look at the air volume. Fresh air volume is an important reference factor for the purchase of fresh air systems. Appropriate fresh air volume can play the role of purification and ventilation. The fresh air volume is too small and the room is not sufficiently ventilated to achieve a reasonable purification and ventilation effect. Large, it will increase the load on the machine and cause energy loss.

Look at installation and after-sales service. According to different needs, you can choose two kinds of pipe installation methods: top delivery top row or ground delivery top row. The central fresh air system has a long service life and generally has to be used for more than ten years. After-sales and maintenance during use cannot be ignored. Anything will wear out after being used for a long time, and the filter of air purification products is even more so, the filter may cause secondary pollution if it is used over time. Pay attention to cleaning or replacing the filter regularly to ensure the long-term and efficient purification effect of the fresh air system. Pay attention to the filter replacement and maintenance services in advance when purchasing.

2. Isn't it necessary to install a fresh air system in a place with good air?

Someone asked if a city with a lot of haze needs a fresh air, and you don’t have to choose it if the air quality is good. In fact, even in cities with good air quality, when we close the windows and close the windows to turn on the cooling and heating indoors, it will affect the circulation of indoor air. The indoor CO concentration will increase over time, and the paint, coating, and bonding after the completion of the mixed decoration Indoor pollutants such as formaldehyde released by agents, the heavy oil fume smell of cooking at home, and the smell of family smoking, etc., lead to the contamination of indoor air, and indoor air quality should be paid more attention.

Simply put, the air purifier filters and purifies the air, and the fresh air system not only provides the function of the air purifier, but also realizes the fresh air, which introduces outdoor fresh air into the room and increases the indoor oxygen content.

4. Can fresh air system replace air conditioner?

First of all, the air conditioner and the fresh air are two systems. The host is different, the connected pipes are different, and the pipes cannot be shared. The main function of central air conditioning is cooling and heating. Fresh air is only an auxiliary function and cannot be used as a replacement for new fans. Similarly, the main function of the fresh air system is to replace indoor and outdoor air to meet the balance of indoor and outdoor oxygen content. It cannot directly adjust the indoor air temperature, nor can it replace the use of central air conditioning.

5. Can new houses be installed in the renovated house?

The renovated house can also choose to install a cabinet or wall-mounted new fan, the operation is simpler, just need to punch holes in the outer wall, and hang the machine on the wall or stand on the wall. The central fresh air system involves pipe drilling operations, and it is more recommended to install houses that have not been renovated.

6. Does the fresh air system need to be on for 24 hours?

The fresh air system is a system that sends outdoor air with high oxygen content through filtering and other treatments, and sends it to the room through pipes. At the same time, the indoor dirty and low oxygen air is discharged out of the room. It is continuously turned on for 24 hours and the machine is always running. A continuous supply of fresh air provides better clean indoor space. In addition, even if the new fan is turned on continuously for 24 hours, due to its low operating power, its power consumption is almost the same as that of a domestic refrigerator.

7. Does the fresh air system need maintenance and how often?

After the fresh air system is installed, the filter screen needs to be cleaned and maintained regularly to avoid secondary pollution and to ensure the indoor air purification effect. It should be noted that when installing the main unit of the fresh air system, sufficient maintenance space should be reserved to facilitate the replacement of consumables in the later stage.

8. How often is the filter replacement frequency of the fresh air system?

In general, the fresh air system will have a reminder function for consumables replacement. According to the actual use environment, the frequency of the filter needs to be changed. If there is a noticeable decrease in air volume, reduced purification efficiency, increased noise, etc., it means that the replacement is required Strainer.

Improve the indoor living environment and make the air more fresh. The fresh air system has gradually become a necessity for home decoration. Learn the basics of buying a fresh air system, choose the most suitable, and create a more comfortable and healthy home.
