摘要(Abstract)：

涡旋压缩机作为空气源热泵的关键部件，其热力学性能对热泵系统有着重要的影响。建立了涡旋压缩机三维瞬态仿真模型，通过实验验证了模型的准确性；基于计算流体力学方法，探究了切向泄漏流影响下涡旋压缩机内部流场非均匀分布流动特性；探讨不同工况参数对涡旋压缩机热力学性能的影响；采用敏感性分析法，讨论涡旋压缩机热力学性能对于不同工况参数的敏感性。结果表明：随着压比的增大，等熵效率先增大后减小，制热量降低，时均排气温度最大增幅为11.26K；吸气温度增至311.65K时，等熵效率增长了16.72百分点；转速的增大会弱化回流现象并降低排气温度，当转速升至4 500 r/min时，容积效率和等熵效率分别增至为86.61%和46.86%。
