A ground source heat pump system: the air conditioning system is composed of a water source heat pump unit, a shallow geothermal energy heat exchange system and a system in a building, and takes rock and soil mass, underground water and surface water as low-temperature heat sources.
Buried pipe heat transfer system: the geothermal energy exchange system is also called as a soil heat exchange system, wherein a heat transfer medium (usually water or water added with an antifreeze) exchanges heat with rock-soil bodies through a vertical or horizontal buried pipe heat exchanger.
The heat exchanger is used for heat exchange between heat transfer medium and rock-soil mass and is composed of underground closed circulating pipe group. According to the pipeline burying mode, the heat exchanger can be divided into a horizontal ground heat exchanger and a vertical ground heat exchanger.
