Large downhole heat exchanger in Turkey and Oregon
- Oregon Inst. of Tech., Klamath Falls, OR (United States). Geo-Heat Center
The multi-tube DHE is more economical to install in shallow wells with high-static water levels; since it can be installed with lighter equipment and has a high output for its short length, it does not require drilling beyond the hot aquifer when the aquifer is near the surface. The vertical convection in the well must also be high to provide adequate heat transfer to the loops. For energy outputs for large demands, the DHE is normally not adequate and thus, some form of pumping with a surface heat exchanger is necessary. A Turkish installation is described that is part of the geothermal district heating system on the west coast of Turkey. A multiple loop installation in Klamath Falls, Oregon is also described.
