%X 针对冬季建筑热负荷典型日逐时变化特点以及燃气机热泵系统运行特性, 提出将储能单元应用于燃气机热泵系统, 建立了系统热平衡模型及评价指标, 基于建筑热负荷波动范围设计了储能单元储放能策略及系统工作模式分区(Mode L, P, F, O), 对系统进行了实验测试, 结果表明加入储能单元后燃气发动机可一直运行在经济转速范围(1 200～2 000 r/min)内, 系统日均一次能源利用率(PERh)为1.48, 较传统燃气机热泵系统PERh提升了4.2% , 燃料消耗量减少12.5% , 较好地平衡了燃气机热泵系统制热量与建筑实时热负荷间的供需关系．<br>According to the hourly changing characteristics of building heat load in atypical winter day and operating performance of gas engine heat pump，an energy storage unit was added to gas engine heat pump system. The heat balance model and evaluating indicator were established. The energy storage/release strategy and the partition of system operating mode(Mode L，P，F and O)were designed based on the wave range of building heating load. A test of the system has been designed. The experimental result shows that the gas engine could entirely work in the economic speed zone(1 200―2 000 r/min)after adding the energy storage unit. The daily average primary energy rate in heating season(PERh)is 1.48 which is 4.2% higher than that of the traditional gas engine heat pump. The quantity of fuel consumption is reduced by 12.5% . At the same time，the energy storage unit could balance the relationship between the heating capacity of gas engine heat pump system and the demand of real-time building heating load well
