Whether the more the fan is opened, the better the ventilation effect is

It is common for most people to think that the more open the fan, the better the ventilation effect, but it is not. Because doors and Windows open the fan is actually the main function is to ensure that indoor and outdoor air can be continuous ventilation, so there is no saying that the more open the fan, the more natural ventilation effect, so there is no inevitable relationship between the two.
