本文提出了一种新的喷射式蒸汽压缩制冷循环。在该循环中，采用具有两个吸入口的喷射器来回收循环的膨胀过程损失。建立了该循环的理论模型，研究了以R32为工质的循环性能。此外，还对该循环与基本蒸汽压缩制冷循环和传统喷射膨胀制冷循环的性能进行了比较。理论研究表明，该循环具有较高的冷（热）量和性能系数。新开发的循环可以为R32制冷剂在空调系统中的应用做出贡献。
This paper presents a new ejector enhanced vapor compression refrigeration cycle operating with the refrigerant R32. In this cycle, an ejector with two suction inlets is employed to recover the expansion process losses of the cycle. The theoretical model for the developed cycle is established and the performance of this cycle using refrigerant R32 is investigated. Furthermore, the performance comparisons of the developed cycle, basic vapor compression refrigeration cycle and conventional ejector expansion refrigeration cycle have also been carried out. The theoretical study shows that the developed cycle gives a higher cooling (heating) capacity and a higher coefficient of performance. The newly developed cycle could make a contribution for the application of refrigerant R32 in air-conditioner systems.
