Ventilation principle:

Natural ventilation in the usual sense refers to the flow of air through purposeful openings. This flow is directly affected by the pressure distribution on the exterior surface of the building and the characteristics of different openings. The pressure distribution is the driving force, and the characteristics of each opening determine the flow resistance. In terms of natural ventilation, there are two main reasons for air movement in buildings: wind pressure and the difference in air density between indoor and outdoor. These two factors can work alone or together.

3. Performance characteristics

1) Energy saving and environmental protection: no power consumption, no new noise source, sustainable ventilation;

2) Effective ventilation: The design of large-area air exchange channels saves energy consumption;

3) High wind pressure resistance: the shell is made of aluminum alloy material, which can be installed in the curtain wall of high-rise buildings;

4) No maintenance required: reasonable structure design, no power components, and all parts and accessories are free from corrosion;

5) Easy installation: In terms of installation, structural design, material selection, etc., different usage conditions are fully considered to ensure its safety and reliability;

6) Insect-proof and dust-proof: the ventilation channel is equipped with a filter with good anti-insect and dust-proof performance;

7) Overall beauty: installation in the curtain wall outdoors does not affect the effect of the building's facade, the indoor panel is closed when it is flat, and it is opened when it is opened
