The specialists distinguish 3 kinds of ventilation: natural, retractable and inlet.

This kind of ventilation doesn’t need any additional means and devices. It is exercised with the opening of windows and doors. The windows can be wide open or just in the mode of micro ventilation. But this kind of ventilation is mostly suitable during a warm season, as during a cold period the warmth would be wasted and there would be a lot of drafts inside.

Retractable ventilation.
This kind of ventilation represents the vertical or horizontal channels, which run in the walls and lead outdoors. Such a system allows pulling the air from the rooms.
