A supply of fresh air to the lower area of the building optimizes smoke and heat ventilation efficiency. The draft creates a chimney effect (natural smoke extraction) and draws smoke more effectively upward.
DIN 18232-2 is increasingly specifying air supply devices in its smoke and heat ventilation system regulations. Fresh air must be planable and controllable like any other smoke and heat ventilation system.
