| 摘 要： | 提出一种压缩／喷射混合制冷循环，该循环相对蒸气压缩制冷循环改动较小，易于实现，钍对此循环进行了理论分析和计算，并与相同工况下的简单蒸气压缩制冷循环作了比较，对７种不同制冷工质讨论了喷射器喷射系数及其效率对循环性能的影响，分析了变工况条件下循环性能系数ＣＯＰ的变化，计算结果表明，新循环能有效地提高循环性能系数。

| Abstract: | A new vapor-compression/ejection refrigeration cycle has been proposed. This cycle hasa little change compared with simple vapor-compression refrigeration cycle and is easy to realize. The theoretic analysis and calculations have been carried out for this cycle. The comparison between the new cycle and the simple vapor-compression cycle are made under thesame operating conditions. The effects of ejector's entrainment ratio and efficiency on thecycle performance have been discussed for seven working substances. The new cycle performance parameter COP variations with off-design operating conditions have been analyzed.The calculated results show that the new cycle can improve the cycle' S performance effectively' |
