Abstract Ground source heat pumps (GSHPs) are one of the renewable energy technologies with features high efficiency, saving, economic feasibility and environmental protection. In China, GSHPs have been widely used for building heating cooling in recent years, shown great potential future development. This paper summarizes classification, development history, use status shallow GSHPs. Several t...

BACKGROUND Ground source heat pumps is a building energy conservation technique. The underground buried pipe heat exchanging system of a ground source heat pump (GSHP) is the basis for the normal operation of an entire heat pump system. METHODS Computational-fluid-dynamics (CFD) numerical simulation software, ANSYS-FLUENT17.0 have been performed the calculations under the working conditions o...

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...

Geothermal Heat Pumps, or Ground Source Heat Pumps (GSHP), are systems combining a heat pump with a ground heat exchanger (closed loop systems), or fed by ground water from a well (open loop systems). They use the earth as a heat source when operating in heating mode, with a fluid (usually water or a water-antifreeze-mixture) as the media transferring the heat from the earth to the evaporator o...
