The fresh air system rose abroad, and in the 1970s, the fresh air system began to be used in Europe and the United States.Although the concept of fresh air has been introduced for 20 years, less than 1%of the newly -built houses in China are currently equipped with new air systems, and it is basically more than 95%of the new buildings.
The reason why the fresh air system has been extremely low for many years is mainly because consumers have not paid enough attention to indoor environmental pollution. The entire fresh air industry lacks systemic propaganda and does not effectively regulate the fresh air industry without the standards of the fresh air industry.
In addition, another reason for the low penetration rate of the fresh air system is its own installation problem. More consumers will choose air purifiers, but there are many problems with air purifiers.It is easy to cause hypoxia, and the air purifier can easily cause secondary pollution.
What is a fresh air system?
The fresh air system can replace the windows and ventilate, and it should be run 24 hours a day.By continuously transporting fresh air filtered indoor, replace harmful gases, and keep the indoor air clean.
The role of the fresh air system
1. There is no dust indoors, not cleaning for 7 days
Most of the dust in the room is caused by opening the window, which allows car tail gas and dust to enter the room.Using a new air system, it effectively avoids the dust from the window into the room.Buying a fresh air system with high -efficiency filter can also block the small meter -level dust into the room.So as to reduce the frequency of cleaning rooms.
2. Keep the indoor slightly pressed and block outdoor outdoor dirty air
The new fan can keep the room slightly pressed by continuously input the filtered fresh air."Block" the door gap by the airflow, blocking the uncured air enters the room through the door joints and other places.
3. Interior air circulation, keep the indoor oxygen content
The fresh air system can continuously transport the fresh air after filtering indoor, which can solve the indoor air non -circulation, resulting in the problem of micro -hypoxia and high carbon dioxide concentration.
4. Ensure the comfort of the indoor environment and maintain good air quality
The built -in energy recovery device of the fresh air system can ensure that the air temperature sent into the room is comfortable and effectively reduce the temperature difference between indoor and outdoor.At the same time, the work pressure of the heating/refrigeration system saves energy and heating costs.
