| 摘 要： | 分析了跨临界CO2引射制冷循环的运行稳定性问题，对蒸气反馈和两级蒸发两种致引射系统稳定的调控方案构建了热力学模型。模拟研究表明蒸气反馈调控系统具有与基本引射循环调控引射系数致系统稳定非常相似的制冷效果。而两级蒸发调控可明显提高系统的制冷性能。引射系数越小，蒸气反馈调控的可调工况区间越窄，两级蒸发方案的可调工况区间越宽。...

| Abstract: | Present work analyzed the operation stability of the transcritical CO_2 ejector expansion refrigeration cycle.Thermodynamic models of two kinds adjusting schemes which maintain cycle stable,i.e.feedback vapor and two-stage evaporation were set up.The simulation result shows that cycle with vapor feedback adjusting control has highly similar refrigeration effect with the basic ejector expansion cycle which controlled by the entrainment ratio.The cycle with two-stage evaporation improves the refrigeration per... |
