Abstract
To design an efficient and cost effective borehole heat exchanger BHE it is necessary to know the thermophysical parameters of the subsurface at the project location The quality management and the examination of existing BHEs are becoming particularly important with the increasing application of ground coupled heat pumps The analysis of data collected from a BHElogger temperaturedepthmeasuring system in a waterfilled BHE allowed several geothermal parameters to be determined A comparison of measurements obtained from the BHElogs geothermal response tests and laboratory soil tests indicated a good correlation In addition to detecting hydraulic short circuits due to defects in the pipe system or backfill material being relatively quick and easy to use the BHElogger can be a valuable tool in the longterm monitoring system and quality control of BHEsPour concevoir un dispositif efficace et rentable d’échange de chaleur en forage il est nécessaire de connaître les paramètres physiques et thermiques du soussol à l’emplacement d’un projet La gestion de la qualité des sondes géothermiques verticales devient particulièrement importante avec le développement croissant des pompes à chaleur couplées à des dispositifs d’échange de chaleur dans les sols Plusieurs paramètres géothermiques peuvent être obtenus à partir d’enregistrements en forage remplis d’eau avec des BHElogger donnant une mesure de la température en fonction de la profondeur Des comparaisons entre des mesures obtenues à partir d’enregistrements en forage de tests de réponse géothermique et de tests sur échantillons au laboratoire ont montré de bonnes corrélations En plus de la possibilité de détecter des courtscircuits hydrauliques dus à des défauts dans le système de tuyauterie ou le matériau de remplissage le BHElogger relativement rapide et facile à utiliser peut être un outil précieux dans un système de surveillance à long terme et de contrôle de qualité des dispositifs d’échange de chaleur en forageThe research borehole Jügesheim and the completion of the BHE was initiated and funded by the Hessian Authority for Environment and Geology HLUG The project partners at the Technical University of Darmstadt the Hessian Agency for the Environment and Geology and at the consulting firm Hamm Theusner GbR are thanked for the funding and provision of equipment and data Special thanks go to Dr Christian Hoselmann at the HLUG who documented the drill cores from the research drilling Jügesheim and contributed to this work
