In vertical closed-loop geothermal systems, the material used to fill the boreholes is an essential element since it facilitates the exchange of heat between holes and pipes which contain the heat transfer fluid. Therefore, the thermal conductivity of this grouting material plays a vital role in conducting heat to the installation; not only does it increase its efficiency with higher thermal conductivity...
The present study shows a new way to calculate a geothermal installation. The process consists in measuring the temperatures inside a perforation. Once we have this parameter, we'll be able to determine the total depth of the perforations in a geothermal installation.With this method, it'll be possible to dispense with other studies which are being used at the moment in this kind of installations...
