Improvements to the ejector expansion refrigeration cycle

The ejector expansion refrigeration cycle (EERC) is a variant of the standard vapor compression cycle in which an ejector is used to recover part of the work that would otherwise be lost in the expansion valve. In initial testing EERC performance was poor, mainly due to thermodynamic nonequilibrium conditions in the ejector motive nozzle. Modifications were made to correct this problem, and significant performance improvements were found.

喷射器膨胀制冷循环（EERC）是标准蒸汽压缩循环的一种变体，其中喷射器用于回收在膨胀阀中原本会损失的部分功。在最初的测试中，EERC的性能较差，主要是由于喷射器动力喷嘴中的热力学非平衡条件。进行了改进以纠正这个问题，并发现性能有了显著提高。
