This paper discusses the research and the state-of-art practices on ground source heat pump systems (GSHP) in
China. It introduces the Chinese patents on GSHP. The GSHP development policies of China, including incentive
mechanism, relevant codes and regulations, are also introduced. In addition, this paper discusses and summarizes the
shortages and imperfects of the current research of the GSHP system and gives some recommendations for future work.
At last, the authors give some advice for the development of ground source heat pump. For more reliable statistics on
geothermal energy use, the obligation to supply an installation report to the relevant authority should also be imposed on
the rural buildings besides urban buildings. GSHP systems are suitable for heating and cooling of buildings and so could
play a significant role in reducing CO2 emissions.
