摘　　要：针对沈阳地区太阳能利用不充分,严寒天气导致空气源热泵易结霜、性能表现较差等问题,以某办公建筑为研究对象,利用TRNSYS软件对相变储能型太阳能-空气源热泵供暖系统参数进行优化调整,该系统依据沈阳市峰谷电价原则对储能系统的热量流动进行调节。研究结果表明:优化后,系统整体性能COP提升了29.5%,当月系统COP最大值可达5.14;太阳能集热器的安装倾角设置为66°时系统的集热效率最高;内插式真空管集热器的月平均效率可达到59.3%,全玻璃真空管太阳能集热器的月平均集热效率可达51.4%;相变材料体积占比与系统的运行费用及系统性能COP均成负相关。Aiming at the insufficient utilization of solar energy in Shenyang area and frosting and poor performance of air source heat pump caused by severe cold weather in winter,this paper takes an office building as the research object,and uses TRNSYS software to optimize and adjust the parameters of phase change energy storage solar-air source heat pump heating system.The system sets and adjusts the heat flow of the energy storage system according to the principle of“peak and valley electricity price in Shenyang”.The overall performance COP of the optimized system is increased by 29.5%,and the COP of the system in that month can reach 5.14;the installation angle of the solar collector is set to 66°,and the thermal efficiency of the solar system is the highest.The average monthly efficiency of the inserted vacuum tube collector can reach 59.3%,and the average collector efficiency of the all-glass vacuum tube solar collector can reach 51.4%.The heat collection efficiency of the inserted vacuum tube solar collector is 8%higher than that of the all-glass vacuum tube solar collector.The phase change material volume ratio is negatively correlated with the operating cost of the system and the system performance COP.
