what is a mechanical ventilation system
Mechanical Ventilation. Mechanical ventilation is a method of forced or induced ventilation by using mechanical air handling systems, commonly called HVAC systems. Mechanical ventilation is more controllable than natural ventilation. In Mechanical Ventilation blowers, fans, filters, and ducts are used for transporting and removing air from a space.There are two types of fans used for the transmission of air. When the air enters the impellers axially and is discharged radially from the impeller, it is called a centrifugal or radial flow fan.t is the movement of air from one space to other as well as supply of fresh air into the air conditioned space. Mechanical ventilation assists in controlling the humidity, contaminants, air borne particles, and general air quality.
