Fresh air circulation
When installing ventilators in a building, it is important to stop and think about how the air behaves. Ventilation is our way of guiding air through the house in order to obtain as healthy and as comfortable an indoor environment as possible.
However, air has a mind of its own and we have to take this into account when planning our ventilation system. We can only help air on its way, we can’t force it, at least not without wasting energy and money on unnecessary fans.
Natural ventilation is based on the fact that pressure and temperature differences cause air to circulate.
The picture shows how cold air comes in (cold air is heavier than warm air and therefore sinks!) which forces up the warm air at which point it is evacuated.
The air is now mixed up and the used air replaced with new, fresh air!
In houses fitted with Velco ventilators each room is supplied with a temperature-regulated, adapted quantity of air. The air circulates draught-free around the whole room and is sucked out from the areas with the most unclean air, e.g. damp areas.
Correct fresh air supply provides draught-free and effective ventilation
Inadequate/incorrect air supply causes poor air circulation.
