GROUND-LOOP HEAT EXCHANGER FOR GROUND HEAT PUMP

摘要

The present invention relates to a geothermal heat pump underground heat exchanger. The present invention, being a circulation pipe which is inserted in the wells is formed of a flexible material enough to be folded reel wound able to raise a small space such as a cellar less space for the lifting of the circulation pipe lifting operation is easy and circulation pipe of even you can install an underground heat exchanger. In addition, without the digging operation in accordance with the installed in the interior of the wells the manhole can facilitate the maintenance operation of the underground heat exchanger. ;
