Forced ventilation
When forced ventilation or mechanical ventilation generally a ventilation method is known, carried away with the humidity or ingress is prevented from flue gases and in which the user does not have the ability to regulate the ventilation or off.
The term is not standardized in ventilation technology , so in principle every ventilation measure without the user being able to intervene would also be forced ventilation.
However, the term is mostly used in connection with air humidity or exhaust gases.
Ensuring forced ventilation is, for example, an essential part of combustion regulations for the commissioning of a combustion system . Gas devices without flame monitoring require a complete exchange of the room air several times during each hour by means of mechanical ventilation.
Doors in bathrooms , toilets and kitchens often do not quite reach the floor or have a built-in ventilation grille in the lower area to support forced ventilation. This is to remove odor and humidity from these rooms, which results in mold on the walls. Forced ventilation can be supported by fans . Coupling of toilet lighting to fans with overrun is widespread.
Forced ventilation as a replacement for manual ventilation
Incorrect manual ventilation can lead to the formation of mold in rooms.
If warm air is brought into a cold room, water can condense on the walls.
To prevent such operating errors (especially in laundry rooms and general rooms ), forced ventilation with fans is used.
Forced ventilation is usually controlled by differential humidity controllers in order to prevent excessive air humidity .
