Heat Exchanger For Geothermal Heat Pump

Warer/ground source heat pump is device for making heat/cold air or heat/cold water. Geothermal heat pump's heat/cold source come from water of buried pipe, well, lake, river,sea, sanitary sewage, industrial sewage etc.
Note：Water can be salt water, Ethylene glycol aqueous solution.

Geothermal heat pump classification
Cold/heat air unit:	heat exchanging devices at user side are coiled pipes with air suppling and adjusting system;
Heat/cold water unit：	heat exchanging devices at user side are heat exchanger of water-refrigeration.
Water loop unit：	using water in public pipe as heat/cold source.
Underground water unit：	using underground water as heat/cold source.
Buried pipe unit：	Using water circularly flow in the buried pipe as heat/cold source.
Surface water unit：	using water in lake, river, sea, sanity sewage, industrial waste water.
