摘　　要：针对空气源辅助地源热泵系统运行控制策略优化问题,提出了一种基于传统地源热泵地埋管空调季逐时出口温度,制定符合热泵系统控制运行温度的方法,并以成都市某办公建筑为研究对象,应用EnergyPlus模拟软件得到25℃、26℃、27℃、28℃和29℃不同控制温度下的系统全年运行数据。从土壤热平衡及综合性能分析,得出25℃作为控制温度为最优运行控制策略,可以实现土壤热平衡。Aiming at the optimization of operation control strategy of air source-assisted ground source heat pump system, this paper proposes a method to control operation temperature in accordance with the heat pump system based on the seasonal hourly outlet temperature of the traditional ground source heat pump(GSHP) underground pipe air conditioning system, and takes an office building in Chengdu as the research object. The annual operating data of the system at different control temperatures of 25℃,26℃, 27℃, 28℃ and 29℃ were obtained by using EnergyPlus simulation software. From the analysis of soil heat balance and comprehensive properties, it is concluded that 25℃ is the optimal operation control strategy to achieve soil heat balance.
