摘　　要：为消除太阳能随机性与不稳定性对建筑供能的不利影响,降低建筑运行能耗,基于TRNSYS建立PV/T耦合水源热泵与溴化锂吸收式制冷机三联供系统模型。以天津市某学生宿舍的太阳能三联供系统为研究对象,探究系统全年运行特性,以系统[火用]效率与投资回收周期为目标函数,以系统关键设备参数与运行参数作为决策变量,通过Grasshopper调用超体积估计算法(HypE)进行优化。研究结果表明,系统能够满足建筑负荷,采用PV/T与水源热泵耦合能够同时提升两者性能,PV/T产电能覆盖系统大部分能耗。优化结果表明,在最优条件下系统的[火用]效率为20.10%,投资回收周期为8.02年。PV/T耦合水源热泵与溴化锂吸收式制冷机系统能够达到更好的能效与经济性。研究结果可为太阳能三联供系统的设计提供理论依据。In order to eliminate the adverse effects of randomness and instability of solar energy on building energy supply and reduce building operating energy consumption,we established a model of the photovoltaic/thermal(PV/T)coupled with water-source heat pump and lithium bromide absorption chiller tri-generation system on TRNSYS.Taking the solar tri-generation system serving a student dormitory in Tianjin as the research subject,we analyzed the system’s performance throughout the year.We performed multi-objective optimization using Hypervolume Estimation method(HypE)in Grasshopper,with system exergy efficiency and payback period serving as objective functions,and key parameters of equipment and operation serving as decision variables.The result indicates that the system effectively meets the load demand of building.The coupling of PV/T with water-source heat pump improves performance of both simultaneously.Furthermore,the power generated by PV/T covers the majority of the system’s energy consumption.Additionally,the optimization results show that the system’s exergy efficiency reaches 20.10%and the payback period is 8.02 years under optimal conditions.In conclusion,the PV/T coupled water-source heat pump and lithium bromide absorption chiller system can achieve better performance and economy.This research can provide a theoretical basis for the design of solar tri-generation system.
