Ventilation building is a way to produce air flow according to the local pressure difference caused by the natural environment and the principle of gas flow, so it does not need power drive, and can save cost and energy. When there is no wind outside, it depends on the stable temperature difference between indoor and outdoor to realize the air exchange flow. When the outdoor natural wind speed is large, the effective air exchange can be ensured by relying on the external wind pressure. The ventilation building can be perfectly combined with the building or external window, without affecting the overall beauty.

Under the same ventilation area, the ventilation effect of ventilation building mainly depends on the following factors:

1、 The temperature difference between indoor and outdoor, shortness of breath to make air pressure flow to drive air flow.

2、 The size of the natural wind outside the room, resulting in a large difference between indoor and outdoor pressure, which makes the air flow.

3、 The influence of temperature is also the cause of air flow and exchange.
