People's requirements for quality of life have increased, but the air quality has gradually declined, and the fresh air system came into being.
Many large public spaces such as shopping malls, stations, and hospitals do not have windows, but the people inside do not feel that the air is stuffy and breathless, because they all have fresh air systems.
The main function of the fresh air system is to bring in fresh air from the outside and exhaust the dirty air with high carbon dioxide content in the room. Fresh air is introduced without opening the window, and in the process of feeding the air, the pollution and bacteria in the air are purified and filtered. In order to prevent outdoor dust and haze from invading the room.
During the heating season or when the outside air quality is poor, people tend to keep their windows closed. Because it cannot be replaced with the outside air, the indoor air becomes dirty and does not flow, and there will be a feeling of slight hypoxia such as suffocation and dizziness in the room for a long time.
What are the situations where fresh air needs to be installed?
Few windows. In apartments with few windows and poor air circulation, harmful gases will remain for a long time after decoration, and the installation of a fresh air system can make the air circulate and quickly discharge harmful substances.
Homes with poor environment.
Living in areas with large haze and dust, or houses with windows facing the road, low floors, and easy to enter dust, such houses are in areas with very poor environmental conditions, and it is necessary to install a fresh air system, which can greatly improve the living conditions.
Families with respiratory diseases.
If there are such patients at home, the requirements for air quality are very high, and the installation of a fresh air system is conducive to disease control.
