Solar-geothermal heat store - has solar collector heating shallow depth of ground layer for annular cyclic storage

摘要

The solar collector works on an annual cycle on sun exposure to accumulate thermal potential by controlled artificial geothermal storage in stable or stabilised ground layers at shallow depth. This technique is natural but accelerated and amplified. The collectors are of the falling water type with the capture covers (8) heating water in the undulations (1,2), the latter being perpendicular to the line of greatest slope of the roof.
