Ventilation

In low-energy and passive houses in particular, it is difficult to provide living rooms with sufficient fresh air to ensure the perfect, pleasant atmosphere. Living room ventilation can help.

Differences between central ventilation and single-room ventilation

How living room ventilation works

The principle of how it works is the same for central and single-room ventilation.

  • Exhaust air is drawn in and blown outside, whilst fresh air is channelled inside.

  • Special filters prevent pollen and particulates from entering.

  • In systems with heat recovery, no heat loss occurs, despite constant ventilation.

  • Devices that operate continuously – so-called permanent ventilators – have two fans, which draw in exhaust and external air in parallel.

  • Push-pull devices or pendulum ventilators have only one fan, of which the running direction is repeatedly reversed.
