SAVEVent Principles

The room ventilation is based on the principles of pressure differences. On these point of view your residential building ventilation technically consist of three zones: exhaust, supply and overflow area.

This is how your controlled residential ventilation works:

Using the rooms, kitchen, bathroom and toilet, your ventilation system vents waste air outside. Depending on the system, a heat exchanger extracts the heat from waste air first. At the same time, fresh air from outside is taken in and filtered.
If necessary, the heat exchanger pre-tempers the cool outside air using the waste air. The fresh air then flows through the vents into the rooms. From there, the supply air flows through openings in the doors (door gap or grille) across the overcurrent area (corridor and floorboards) into the kitchen, bathroom and toilet. This way, the two different types of air don’t mix.

The result: an optimum air ratio and a pleasant room climate.
