地源熱泵系統在北京大興國際機場的應用
Application of ground-source heat pump systems to Beijing Daxing International Airport
摘要：
為了實現北京大興國際機場可再生能源利用率不低于10%的建設目標，在機場工作區，圍繞蓄滯洪區開展了地源熱泵系統的建設，該系統設置了2座集中能源站，淺層換熱孔10 680 個，總供能面積257萬m2。該項目充分利用淺層地熱能，耦合天然氣、電力等常規能源，結合煙氣余熱回收、冰蓄冷、大溫差等多項節能技術，在高效性、安全性、節能性、環保性和經濟性上實現了可再生能源和常規能源的互補。
Abstract：
In order to achieve the construction target of Beijing Daxing International Airport that the utilization rate of renewable energy is not less than 10%, the construction of a ground-source heat pump system is carried out around the flood storage and detention area of the airport. The system sets up two centralized energy stations and 10 680 shallow heat exchange holes to supply energy for the area of 2.57 million square meters. The project makes full use of shallow geothermal energy, coupled with conventional energy such as natural gas and electricity, combined with a number of energy-saving technologies such as flue gas waste heat recovery, ice cool storage, large temperature difference and so on. In terms of efficiency, safety, energy saving, environmental protection and economy, the renewable energy and conventional energy are complementary to each other.
