Nobao ground source heat pump
The Nobao ground source heat pump system whose heat source or heat sink is is soil, groundwater and river water, differentiated from the air source heat pump system. In ground source heat pump system, water is the carrier of cold and heat energy, circulating between the heat pump units through the heat exchange pipe buried in the soil, so as to realize the heat exchange between unit and soil. In winter, circulating water absorbs heat from the soil by the high density polyethylene pipe loop buried in soil, so as to increase the temperature of circulating water and supply it to the GSHP units. Providing hot water after the "temperature lifting" of the heat pump unit, and indoor heating through the indoor terminal system; In summer, the indoor terminal system heat is "extracting" indoor heat to the heat pump unit, resulting in cool indoor environment. Heat pump units extract this part heat along with the heat pump power consumption into the soil through a condenser. The heat source temperature of the geothermal is relatively stable throughout the year, it is higher in winter and lower in summer than the ambient temperature. This makes the ground source heat pump system more efficient than the traditional air source heat pump system, and it is 30% ~ 50% more efficient than the traditional air conditioning system.


As illustrated:
   In winter, ground is as the heat source for our GSHP system, and closed underground Double-U pipelines extracts heat from the ground for inner building and hot water supply.
As illustrated:
In summer,ground is as the heat extracting place for our GSHP system, and closed underground Double-U pipelines system is supplying cooling to the room, extracting indoor heat to the ground and recycling the waste-heat for free hot water supply.
As it is well-known, the temperatures at 15 meters below the ground surface is relatively stable between 10-15 ℃ throughout the year, which provides endless free energy exchanging source for the our GSHP systems..
