摘要(Abstract)：

针对蓄热水箱容积以及集热循环泵流量对蓄热型太阳能光伏光热组件与热泵一体化系统的整体能效有影响。建立了基于■效率的系统整体性能指标,利用TRNSYS软件搭建了系统仿真模型,通过输入试验环境参数将模拟结果与试验结果进行了对比分析,发现试验数据和模拟数据的变化趋势基本一致。最后利用该仿真模型对系统进行了模拟研究。分别对蓄热水箱蓄水量为300,500,700 L时系统运行的整体■效率进行计算,结果表明蓄热水箱容量为500 L时系统的运行效率最高。对集热循环水泵流量分别为0.9,1.1,1.3,1.5 m~3/h时系统的运行状况进了模拟研究,得出集热循环水泵最佳流量为1.1 m~3/h。
Considering the influence of heat storage water tank volume and heat collection circulating pump on the overall energy efficiency of the integrated system of the solar photovoltaic solar-thermal components,the overall performance index of the system based on exergy efficiency was established.Then the system simulation model was built by using TRNSYS software.The simulation results were compared with the experimental results by inputting the experimental environmental parameters.It is found that the trends of the experimental data and the simulated data were basically the same.Finally,the simulation model was used to simulate and optimize the system.The overall exergy efficiency of the system was calculated for the heat storage water tanks of 300,500,700 L,respectively,and the system efficiency was the highest when the heat storage water tank was 500 L.After that,the operating conditions of the system were simulated at the flowrates of the heat collecting pump of 0.9,1.1,1.3,1.5 m~3/h,respectively.It was found that the optimal flowrate of the collector pump was 1.1 m~3/h.
