摘　　要：以包头市某住宅楼为研究对象,建立太阳能跨季节储热-地埋管地源热泵联合系统仿真模型,对系统的长期运行特性进行预测分析。将仅配置热泵机组(与联合系统的热泵机组额定参数一致)的地埋管地源热泵系统作为比较对象,测算联合系统经济性。采用太阳能跨季节储热,可实现地温平衡,可有效保证地埋管地源热泵长期稳定高效运行。与地埋管地源热泵系统相比,联合系统增量投资回收期为13.7 a。若考虑供暖期利用太阳能制取生活热水,联合系统的经济性可进一步提升。Taking a residential building in Baotou City as the research object,a simulation model of solar inter-seasonal heat storage and underground pipe ground source heat pump combined system was established to predict and analyze the long-term operation characteristics of the system.The economy of the combined system was calculated by taking the underground pipe ground source heat pump system with only the heat pump unit(consistent with the rated parameters of the heat pump unit of the combined system)as the comparison object.The use of solar inter-seasonal heat storage can achieve ground temperature balance,which can effectively ensure the long-term stable and efficient operation of the underground pipe ground source heat pump.Compared with the underground pipe ground source heat pump system,the incremental investment payback period of the combined system is 13.7 years.If the use of solar energy to produce domestic hot water during the heating period is considered,the economy of the combined system can be further improved.
