摘　　要：以严寒地区一栋办公建筑空气源热泵供热(ASHP)系统为研究对象,实地调研系统设计与运行数据,分析ASHP系统供热效果并提出改造优化方案。利用TRNSYS软件构建太阳能光伏空气源热泵耦合供热系统(PV-ASHP系统)、太阳能光热空气源热泵耦合供热系统(SC-ASHP系统)和太阳能光伏光热空气源热泵耦合供热系统(PV/T-ASHP系统)模型,研究改造方案可行性。结果表明:相较于改造前系统,改造后系统中SC-ASHP系统与PV/T-ASHP系统性能系数(C_(cop))为7.10、6.57,PV-ASHP系统与PV/T-ASHP系统运行能耗降低约50%,PV/T-ASHP系统太阳能利用率最高,达61.51%。In order to solve the problems of air source heat pump heating system(ASHP system)in severe cold region,such as substandard heating effect,low efficiency and high energy consumption,it is necessary to reform and optimize the energy systems.The research object was the ASHP system of an office building in severe cold region.The system design and operation data were investigated on site,the heating effect of the ASHP system was analyzed,and an optimization plan for renovation was proposed.The models of solar photovoltaic air source heat pump coupled heating system(PV-ASHP system),solar thermal air source heat pump coupled heating system(SC-ASHP system),and solar photovoltaic thermal air source heat pump coupled heating system(PV/T-ASHP system)were constructed by TRNSYS software to study the feasibility of the transformation scheme.The results showed that compared with the heating system before the transformation,the C_(cop) of the SC-ASHP system and the PV/T-ASHP system can be increased to 7.10 and 6.57.The energy consumption of the PV-ASHP system and the PV/T-ASHP system is reduced by 50%,and the solar energy utilization rate of the PV/T-ASHP system is the highest,reaching 61.5%.
