摘　　要：通过对西北严寒半干旱地区太阳能-地源热泵系统的优化配比进行研究,达到提高系统性能的目的。以包头市居住建筑为模型,对3种不同太阳能与地源热泵联合运行的模式进行仿真,结果表明,集热器侧一部分接入地埋管出口端、另一部分接入热泵机组出口端的模式性能最优,系统运行20 a后的COP从5.48减小至4.99,降低了9%。提出了负荷比和循环流体的分流比,当集热器侧承担总热负荷的40%左右时,COP最高,较最优模式下的COP(5.48)提高了1.45%。集热器侧分流比为0.6时,较优化前的平均COP提高了6.8%。By studying the optimal ratio of solar-ground source heat pump(SGSHP)systems in the severe cold and semi-arid region of Northwest China,the goal of improving the system performance is achieved.Taking the residential buildings in Baotou as the model,three different modes of the combined operation of solar and ground-source heat pumps are simulated.The results show that the performance of the mode in which one part of the collector side is connected to the outlet end of the buried pipe and the other part is connected to the outlet end of the heat pump unit is the best.The COP of the system after 20 years of operation has decreased from 5.48 to 4.99,which decreases by 9%.The load ratio and the split ratio of the circulating fluid are proposed.When the collector side takes about 40%of the total heat load,the COP is the highest,which increases by 1.45%compared with the COP of 5.48 under the optimal mode.When the split ratio on the collector side is 0.6,the average COP before optimization is increased by 6.8%.
