Beijing's Demonstration Activities in Geothermal Source Heat Pumps in China

Abstract

Beijing started with geothermal source heat pumps(GSHP) relatively earlier and now is one of the pioneer cities of this booming technology and market in China. There were more than 8 million m2 building areas installed with geothermal source heat pumps, about 30 million m2 are planed to be installed before 2010, most of which use underground water as the heat source. Owing to its environment-friendly and energy-saving characteristics geothermal source heat pump is on the one hand encouraged by some incentive policies and on the other hand is regulated by the government. Considering that about 335 million tons of standard coal will be saved with GSHPs in 2020 when there will be more than 70 billion m2 building areas in China, it can be predicted that GSHPs will be the most favorable choice for space heating. The demonstration activities are discussed and analyzed in this paper.
