Aerating windows

Heat recovery ventilation can be integrated into windows, walls, shutters, and heating and cooling units. HRV provides fresh air and improved climate control, while also saving energy.

In winter, fresh outdoor air is filtered, freely preheated and supplied to the room for the benefit of the occupants. At the same time, an equal quantity of waste air is extracted, cooled and transferred outside. The same heat transfer takes place inversely in hot conditions (summer). The amount of supplied air can be based on an occupancy profile, indoor air quality measurement, or need of the occupants.

The heat recovery technology is based on the fabrication of a multitude of micro-channels made from synthetic thin foil material, resulting in the development of high surface density (close to 900m²/m³) arranged in as counter flow and providing for primary surface heat transfer. This is the most effective way to achieve high thermal effectiveness together with low pressure drops.

The use of thin foil associated with small hydraulic diameters also provides a high heat transfer rate from one flow to the other, as well as a good thermal insulation between outer and inner environments.

BRICKER will draw on this technology developed by Greencom. It meets the need of high performing refurbishment programmes particularly well. However, in public buildings, some additional challenges need to be overcome, for instance, increasing the airflows, facilitating adaptation, and raising effectiveness at low flow.

The Greencom technology will be installed and demonstrated in the Belgian SPB demo site.
