2. Direct exchange geothermal heat pump - Wikipedia

   en.wikipedia.org/wiki/Direct_exchange_geothermal...

   DX system being drilled in the 1980s. A direct exchange (DX) geothermal heat pump is a type of ground source heat pump in which refrigerant circulates through copper tubing placed in the ground unlike other ground source heat pumps where refrigerant is restricted to the heat pump itself with a secondary loop in the ground filled with a mixture of water and anti-freeze.

3. Ground source heat pump - Wikipedia

   en.wikipedia.org/wiki/Ground_source_heat_pump

   The direct exchange geothermal heat pump (DX) is the oldest type of geothermal heat pump technology where the refrigerant itself is passed through the ground loop. Developed during the 1980s, this approach faced issues with the refrigerant and oil management system, especially after the ban of CFC refrigerants in 1989 and DX systems now are ...

   That heat can be extracted with a geothermal heat pump more efficiently than it can be generated by conventional furnaces. [10] Geothermal heat pumps are economically viable essentially anywhere in the world. In theory, geothermal energy (usually cooling) can also be extracted from existing infrastructure, such as municipal water pipes. [14]

6. Copper in heat exchangers - Wikipedia

   en.wikipedia.org/wiki/Copper_in_heat_exchangers

   Geothermal heat pump technology, variously known as "ground source," "earth-coupled," or "direct exchange," relies on circulating a refrigerant through buried copper tubing for heat exchange. These units, which are considerably more efficient than their air-source counterparts, rely on the constancy of ground temperatures below the frost zone ...

7. Glossary of geothermal heating and cooling - Wikipedia

   en.wikipedia.org/wiki/Glossary_of_geothermal...

   The refrigerant in the heat pump either extracts heat from the fluid or rejects heat to it, cooling or warming the refrigerant. When heat is absorbed by the refrigerant, the heat pump boosts its temperature and sends it to the air handler to circulate hot air to heat the home and (optionally) to a hot water heater to produce domestic hot water.
