| 摘 要： | 文中提出了两相流引射制冷循环系统稳定工作判据,并据此对传统两相流引射制冷循环系统进行了改进,增加了辅助蒸发器以使系统稳定工作.在此基础上,对以R134a为制冷剂的汽液两相流引射制冷循环的系统性能进行了数值模拟,分析了不同工况、不同引射比对系统性能的影响.数值模拟结果表明:在给定冷凝压力和蒸发压力工况下,两相流引射制冷循...

| Abstract: | The stability criterion of the two-phase ejector refrigeration(TPER) cycle was proposed.On the basis of this criterion,the traditional TPER cycle was improved with adding an auxiliary evaporator.The performance simulation of the new TPER cycle with the refrigerant R134a was carried out,and the effects of the working conditions and the entrainment ratio on the system performance were analyzed.The numerical simulation results show that,at the conditions of fixed condensing and evaporating pressures,there is a... |
