Gi mechanical ventilation systems are systems that allow to manage the
air exchange of a room with the outside.
This happens without the opening of windows or doors, through pipelines of forced ventilation, connected with indoor environments so you can remove stale or polluted air and introduce new air. In the common diction these systems are also referred to as ventilation controlled mechanics (VMC).
Mechanical ventilation can be a completely independent system or integrated into the air conditioning system.
