摘　　要：采用稳态仿真的方法对双级压缩热泵系统的压缩机部件建立模型,并建立中间冷却器模型。由于在低温工况下试验,模型建立考虑了压缩机和环境的换热。通过建立试验台,采集试验数据并与仿真结果进行比较。结果表明,稳态仿真能够良好地反映系统运行中的参数变化。Establishes compressor model for two-stage compression heat pump system by the steady-state simulation method, and the model of middle chiller. Because experiments are done under low temperature, the model of compressor and the environment＇s heat transfer must he considered. Through setting up the test platform, collects tentative data and compares with the simulation results. Proves the simulation result can well reflect the parameter variation of systems operation.
