Ground source heat pump (GSHP) technology was used in China not long, but the application speed is very fast, almost at an annual rate of over 20% growth, especially applied in the Expo 2010 Shanghai in large scale, to obtain good energy saving effect. With the application of the technology and in-depth research, China has mastered the full range of GSHP technology, and in the technical regulations for shallow geothermal energy investigation and evaluation, bore thermal response testing techniques, efficient underground heat exchange wells, and joint application of solar and GSHP technology have made new progress, these achievements will be the realization of China's energy-saving emission reduction targets by 2050 to provide technical support.
