The application of gas engine driven heat pump (GHP) system can improve the peak valley difference of power and gas system and promote the low-carbon utilization of energy system. The energy consumption of GHP system in different types of buildings and especially the coefficient of performance (COP) under partial load rate needs more analysis. In this paper, according to the local meteorological parameters in Shanghai, the COP operation curve of GHP and electric driven heat pump (EHP) units under partial load rate was analyzed. Combined with the load calculation, the annual energy consumption of GHP and EHP units in different types of buildings, and the influence of energy price on economy of GHP system were analyzed. For office buildings and catering buildings, the energy consumption and operating costs of GHP system were slightly lower than those of EHP system, while for hotel buildings, the annual operating costs of GHP were lower than those of EHP only when the winter gas price was 2.39 yuan/m³ and the summer gas price was 2.19 yuan/m³. Therefore, in order to promote the market competitiveness of gas air conditioning, it is necessary to further refine the gas price or charge standard.

燃气发动机驱动热泵（GHP）系统的应用可以改善电力和燃气系统的峰谷差，促进能源系统的低碳利用。不同类型建筑的GHP系统能耗，尤其是部分负荷率下的性能系数（COP）需要更多分析。本文根据上海当地气象参数，分析了GHP和电驱动热泵（EHP）机组在部分负荷率下的COP运行曲线。结合负荷计算，分析了不同类型建筑的GHP和EHP机组年能耗，以及能源价格对GHP系统经济性的影响。对于办公楼和餐饮楼，³、夏季燃气价格为2.19元/m ³。因此，为提升燃气空调的市场竞争力，有必要进一步细化燃气价格或收费标准。
