The nomination took place on November 6th in Vienna and honors the geoAir project, a patented solution that combines a geothermal heat pump with central living room ventilation. This development enables a significant increase in efficiency and conservation of resources when using geothermal energy. With geoAir, costs and space requirements can be significantly reduced as the size of the geothermal source can be reduced by up to 40%. This is achieved through intelligent earth source regeneration, in which the exhaust and outside air from the ventilation system is used during the heating season.
geoAir Technology
● The central innovation is the use of exhaust and outside air to heat brine via two heat exchangers, which enable soil regeneration even during the heating season. From an outside temperature of 6°C, more energy is regenerated than is extracted from the ground
● The outside air is preheated by the geothermal heat source when the outside temperatures are very cold without the use of electrical preheating, thereby increasing the efficiency of the ventilation system.
● In summer, the outside air regenerates the soil, while part of the passive cooling energy is transferred into the house via the air. This prevents excessively warm air from entering the house on hot days.
In a new building project in the Bregenzerwald in Austria, the use of geoAir enabled the costs for earth development work to be reduced from the originally projected €140,000 to €80,000 (-43%). As part of the new building project mentioned, which is considered the first major project with three buildings and a net usable area of around 2500 m2, the geoAir system was implemented for the first time in a major project. Thanks to the use of geoAir, it was possible to switch from the originally planned length of 1550 m of earth probes to a combination of earth probes (3 x 81 m) and ring trench collectors (200 m trench length). The total heating output is 95 kW. These points underline the economic benefit of the solution and offer an attractive option for both residential and commercial construction.
These figures underline the economic benefit of the solution and offer an attractive option for both residential and commercial construction. Efficient for generations – Weider heat pumps contribute to reducing CO2 emissions. High quality standards and production in Austria promise reliably working heat pumps with a long service life as well as first-class customer service. The company has received several innovation awards for this. ■
