摘　　要： 将喷射器用于涡旋压缩机补气的热泵系统中。用实验数据拟合出了补气工况下压缩机指示效率，建立喷射器补气热泵系统的热力学分析模型，对其运行性能进行了分析。结果表明，相对于普通补气系统，喷射器补气热泵系统不降低系统的制热量，制热能效比可提高3％-5％；喷射器补气热泵系统的适宜补气压力为0.85-1.0MPa。 Ejectors were used in the blowdown heat pump system of scroll compressors. The indication efficiency of the compressors under blowdown conditions was fitted using experimental data, the thermodynamic analysis model of the blowdown heat pump system of the ejectors was founded, and an analysis was made of its operation performance. The result shows that in comparison with common blowdown system, the blowdown heat pump system with an ejector does not low the heating capacity of the system, its heating EER can be raised up 3%-5%, the suitable blowdown pressure of the blowdown heat pump system with an ejector is 0.85-1.0MPa.
