阳台壁挂太阳能—空气源复合热泵系统的仿真模拟和实验验证

Simulation and experimental verification of solar-air compound source heat pump system hanging on balcony

针对自行设计的一台3.6kW阳台壁挂太阳能—空气源复合热泵样机,建立了样机各部件的仿真模型,并对其冬、夏季运行模式进行了仿真模拟,模拟结果显示:在名义工况和最大负荷工况下复合热泵性能优于空气源热泵。通过与样机实验测试结果对比,仿真模拟误差在允许范围之内,模型精度达到系统主要性能的要求。

In this study, the simulation model of hanging on balcony of solar-air compound source heat pump system has been established by model machine with power capacity of 3.6kW. Simulations of summer and winter operation modes have been conducted. Simulated results indicate that the performances of compound source heat pump are better than that of air source heat pump under nominal mode and maximum load mode. The error of simulation results compared with experimental result is in the permission scope. The precision of simulation model comes up to the performance requirements of the system.
