摘　　要：分别以冷负荷为矛盾的地区(成都、郑州)和热负荷为矛盾的地区(拉萨)为研究对象,分析在不同地区空气源辅助地源复合式热泵系统的适宜性。针对某办公建筑,设计两种复合式地源热泵系统,通过EnergyPlus模拟得到系统运行能耗,并分析其综合性能。由此得出,以冷负荷为主要矛盾且土壤热不平衡率较大地区,冷却塔辅助复合式地源热泵系统更适宜,而在土壤热不平衡率较小地区和热负荷为主要矛盾地区,空气源辅助地源复合式热泵系统更加适宜。In this paper,the regions where the cooling load is contradictory(Chengdu,Zhengzhou) and the heat load is contradictory(Lhasa) are taken as the research object,and the suitability of the ground-source composite heat pump system assisted by air source in different regions is analyzed.Two kinds of composite ground source heat pump systems are designed for an office building.The energy consumption of the system is simulated by EnergyPlus,and the comprehensive performance is analyzed.It is concluded that the cooling tower-assisted composite ground source heat pump system is more suitable in the area where the cooling load is the main contradiction and the soil thermal imbalance rate is large.However,in the areas where the soil thermal imbalance rate is small and the heat load is the main contradiction,the air-source assisted ground-source composite heat pump system is more suitable.
