Ventilation with heat recovery for comfort
A ventilation system with heat recovery ensures that plentiful, nearly room temperature fresh air enters the building in a controlled manner. Draughts are eliminated and residents need not actively air out the rooms. It is important that the fresh air entering the building not exceed 30m³ per hour per person, so as to avoid overly dry air. Such a ventilation system should not be confused with air conditioning systems; humidifying the air within the ventilation system is to be avoided for reasons of hygiene.
