Direct exchange geothermal heat pump - Wikipedia

A direct exchange (DX) geothermal heat pump is a type of geothermal heat pump (or ground source heat pump) in which refrigerant circulates through copper tubing placed in the ground. It is a closed-loop, refrigerant-based geothermal system. Direct exchange geothermal heat pumps function similarly to air source heat pumps, according to the principles of vapor compression refrigeration, except
