Paper No 167 – Cost optimized design of ground probe fields with solar regeneration – 13th IEA Heat Pump Conference, Jeju, Korea
Solar regeneration is often used to raise the temperature of the ground above the natural level in order to enable a more efficient operation of heat pumps. The aim of this simulation study was to find the most cost-effective configuration ofground probes in combination with solar regeneration. The results show that with the help of regeneration not only the costs, but also the efficiency of the heat supply can be improved in comparison to the case without regeneration. Besides that, good conditions are achieved for freecooling with the ground probes despite the regeneration, as well.
