Reverse ventilation system to mechanical ventilation controlled "classic", mechanical ventilation by insufflation® is a ventilation system not widespread in France, but yet very effective to allow to renew the ambient air of a house while fighting against 'humidity. If you want to install mechanical ventilation by insufflation®, here are some tips.
Principle of mechanical ventilation by insufflation®
Where the "classic" VMC evacuates stale air from the home, mechanical ventilation by insufflation® (VMI®) is based on the principle of insufflation of fresh air in the home, and therefore puts the latter in overpressure . Before being blown into the rooms of the house, the incoming air is previously filtered and preheated.
Installation of mechanical ventilation by insufflation®
The mechanical ventilation system by insufflation® consists of a box, generally made of steel, equipped with a fan, a resistor for heating the air, a dust filter and a system of regulation. The box, installed in the attic of your home is connected to one or more air vents which will allow to breathe new air inside the home. Stale air will be evacuated naturally by installing high ventilation in damp rooms (bathroom, toilet, kitchen) or through the "leaks" of the housing thanks to the principle of overpressure.
