The geoAir system by Weider Wärmepumpen combines a brine heat pump with a central ventilation system, which allows for the regeneration of the ground heat source using exhaust and outside air during the heating period. In summer, it cools the supply air through the ground heat source, and in winter, the ground heat is also used to prevent the ventilation heat exchanger from freezing. Simulations show that up to 60% of the required extraction energy can be regenerated during the heating period.
