Arrangement for recovering geothermal heat near surface has heat exchanger(s) between starting, destination pits so as to be horizontal or parallel to surface and at sufficient depth to prevent influence of seasonal temperature fluctuations
摘要
<p>The arrangement has one or more heat exchangers (1) arranged between a starting pit (2) and a destination pit (3) so as to be horizontal or parallel to the terrain surface and at a sufficient depth at which the influence of seasonal temperature fluctuations is excluded. A separate feed and return are arranged at a distance apart so as to prevent their mutual thermal influence.</p>
