Oberfeld – Large PVT plants for ground source regeneration
In this P&D project the potential of large PVT plants used for ground source regeneration is studied. The complex Oberfeld consists of three buildings. Each of the three buildings has its separate heating system containing heat pumps, earth probes and a PVT solar plant. The PVT plant is one of the largest of its kind in Switzerland. The entire PVT plant consists of a total of 799 PVT collectors and has an overall area of more than 1300 m², distributed over the roofs of the three buildings. The heat from the PVT plant is primarily used for ground source regeneration, but it can also be used to provide heat directly for the evaporator of the heat pump.
Within this 5 years P&D project the interaction of the entire heating system will be optimized and the long term temperature development and behavior of the ground source with solar regeneration will by observed.
