Research on operating mode of photovoltaic/thermal combined dual-source heat pump systems(2):System simulation study in heating season

使用TRNSYS软件建立了光伏光热-双源热泵(PV/T-DSHP)系统的仿真模型。选取夏热冬冷地区某一近零能耗居住建筑作为研究对象,模拟研究了供暖季PV/T-DSHP系统在COP_(s)切换模式下的运行特性和能耗。结果表明:平均光电效率为15.08%,平均光热效率为33.05%;水源热泵运行模式下供暖季平均COP为4.55,空气源热泵运行模式下供暖季平均COP为3.19,PV/T-DSHP系统的平均COP_(s)为2.98;供暖季系统自满足率为61%。

This paper uses TRNSYS software to establish a simulation model of a photovoltaic/thermal combined dual-source heat pump(PV/T-DSHP)system.A nearly zero energy residential building in the hot summer and cold winter zone is selected as the research object,and the operating characteristics and energy consumption of the PV/T-DSHP system under COP s switching mode during the heating season are simulated.The results show that the average photoelectric efficiency is 15.08%,and the average photothermal efficiency is 33.05%.The average COP of the heat pump unit is 4.55 in the water-source heat pump operating mode,and 3.19 in the air-source heat pump operating mode during the heating season.The average COP s of the PV/T-DSHP system is 2.98.The system self-satisfaction rate during the heating season is 61%.
