| Abstract | Compared with conventional geothermal energy, shallow geothermal energy is widely distributed and easy to exploit, which is an ideal heat or cool source for buildings. As the capital of China, Beijing is one of the earliest cities of developing and utilizing shallow geothermal energy. The application area of ground source heat pump projects has more than 150% annual growth rate in recent years since the first ground source heat pump project completed in 2000. The total application area is more than 38,000,000 square meters in Beijing by 2012. This paper proposes appropriate modes of development and utilization and divide the suitable areas of shallow geothermal energy according to the resource conditions of shallow geothermal energy in Beijing. Combined with the city construction planning of Beijing, it also proposes the development prospects of shallow geothermal energy utilization and the expected economic and environmental benefits. At last, it discusses the key technology problems of large scale application of shallow geothermal energy based on the successful experiences of ground source heat pump project construction, operation management and monitoring. According to the monitoring data of Beijing's ground source heat pump projects, the utilization of shallow geothermal energy for large-scale building heating and cooling has significant energy saving benefits. The development and utilization of shallow geothermal energy has great importance for relieving energy pressure, improving energy structure and transforming to low-carbon economical society in Beijing. |
