• Exhaust System

• Supply System

• Balanced System

• Plenum System

systems use a fan to pressurize a structure, forcing outside air into the building while air leaks out of the building through holes in the shell, bath and range fan ducts, and intentional vents

• Exhaust System

• Supply System

• Balanced System

• Plenum System

The system exhausts air from the house, thus causing a change in pressure that pulls in make-up from the outside through leaks in the building shell and intentional, passive vents

• Exhaust System

• Supply System

• Balanced System

• Plenum System

system usually has two fans and two duct systems. Fresh air supply and exhaust vents can be installed in every room

• Exhaust System

• Supply System

• Balanced System

• Plenum System

The system install in buildings are enclosed spaces that are not for human occupancy, but are often used for heating, ventilating, and/or air-conditioning equipment and airflow, and for other equipment such as cables, piping, and luminaries

The importance of mechanical ventilation are?

• To get enough air – quality and quantity.

• To control ventilation systems

• To control environment air – air velocity, location, way of use.

• To remove heat and dirty air
