Ventilation Systems Cape Town
Ventilation is the process of replacing air in a room.
Ventilation involves maintaining air quality and temperature control, oxygen replenishment, and removal of moisture, odors, smoke, heat, dust, airborne bacteria,
and carbon dioxide.
Ventilation is also tasked with the removal of unpleasant smells and excessive moisture, introduces outside air,
keeps interior building air circulating, and prevents stagnation of the interior air.
Ventilation also includes the circulation of air within a building.
Rate of ventilation
The rate of ventilation for an area is normally expressed in ‘air changes per hour’, i.e. the number of times per hour that the entire air volume of the area is changed.
Calculation fan size
Calculate the volume of the room in cubic meters by multiplying its length x width x height. Then multiply the room volume by the required number of air changes per hour, i.e.
Fan volume (m3/hr) = Length(m) x Width(m) x Height(m) x air changes per hour
