Ground source heat pump, taking the earth as heat and cold source, exchange cold and heat with the earth through the heat pump's heat exchanger which is buried in the ground. In winter, absorb heat from the earth to make circulating water temperature rising and then supply to ground source heat pump unit and then provide heating for buildings through by heat pump. In summer, circulating water discharge the heat to the earth through underground pipes, temperature reduced circulating water was supplied to heat pump unit and then provide cooling for buildings.
This system can be used in cold or tropical areas and also water shortage regions but need certain outdoor buried pipe area. This system can be widely used in office building, hotel, school, dormitory, hospital, restaurant, shopping mall, villa and residence etc.
