Abstract:Geothermal Source Heat Pump(GSHP)is developing fastest in current world to exploit geothermal energy. It is also one of the most hopeful fields in our country to directly exploit geothermal sources. Economy, environmental protection, and technological feasibility of GSHP were discussed. The construction methods, such as well drilling, well completion and installation of underground heat exchanger, and the current development situation in China were introduced. The long-range perspective of GSHP also was looked ahead. Finally it was pointed out that the international cooperation should be strengthened to promote the application and popularization of GSHP in China.
