Ground source heat pump is a form of water source heat pump, which uses water and geothermal energy (groundwater, soil or surface water) for cold and heat exchange as the cold and heat source of water source heat pump, and "takes" the heat from geothermal energy for indoor heating in winter, when geothermal energy is the "heat source"; In summer, indoor heat is taken out and released into groundwater, soil or surface water. At this time, geothermal energy is a "cold source".
