Scientific achievements and regulation of shallow geothermal, systems in six European countries - A review

摘要

The aim of this paper is to review the recent scientific literature concerning geothermal heat pumps and the existing regulations and/or technical guidelines in selected European countries. Focus was put on the environmental effects caused by open- and closed-loop vertical systems. Research was narrowed down to authors with affiliations in the European Union and scientific results of five countries were discussed in detail. Legislation is viewed in perspective of the scientific findings.
