摘　　要：为进一步提高能源利用率,降低综合运行成本,对太阳能-空气源热泵复合供暖系统的流量进行了优化研究。首先利用TRNSYS仿真软件建立了系统模型,然后以采暖季总运行成本最小为优化目标,以三个循环回路的流量为优化变量,以热舒适性评价指标为惩罚函数,采用模式搜索算法进行了优化计算,给出了流量的最优值,并与用传统方法给出的设计值进行比较。结果表明,优化后系统总运行成本更低(可降低21.5%)。研究结果可为太阳能与热泵复合供暖系统优化提供参考。In order to improve the energy efficiency and reduce the comprehensive operation cost,the flow rates of the solar energy air source heat pump composite heating system are optimized.First,system model is established using TRNSYS simulation software,then with the minimum total operation cost of a heating season as the optimization goal,and the thermal comfort evaluation index as the punishment function,the pattern search algorithm is used for optimizing the three loop flow rates.The results are compared with the design values using traditional method,which show that the total operating cost of the optimized system is lower(by21.5%).For all,what we have found can provide reference for solar energy and heat pump combined heating system optimization.
