Abstract

In a geothermal installation, the heat produced is measured for each borehole in order to determine the number required. This is achieved by temp. measurement in the presence of a fluid which cools the circulating fluid. A heat carrying fluid (3) is contained in a thermally insulated (2) reservoir (1) and is pumped (5) through a heat exchanger (6) in a bore hole (15). Thermometers (7, 8) measure outlet and inlet temperatures (T1T2) of the reservoir. A U-shaped pipe (11) is immersed in the reservoir and carries a refrigerating fluid (12) produced from a heat source whose power is known. As fluid circulates via the borehole the temp. are measured and the pump speed is controled such that bore hole losses equal the cooling power of the refrigerating fluid. By plotting values on a graph, the calorific power can be determined for the bore hole.
