Building heating system with external solid solar energy heat absorbers

摘要

The heating system has a forced feed for the flow path of the energy-carrying fluid from the solid solar heat absorber (10) to the buried heat storage unit (40) and from them to the heat exchanger system (42). The forward (32) and return (34) flow channels lead from a number of solid heat absorbers (10) to collection channels with their return flows linked to the heated fluid in the buried heat stores (40), which have a collection channel linked to a heat pump (42).
