摘　　要：在蒸汽压缩式制冷循环中使用膨胀机代替节流阀,可以减少不可逆损失,回收膨胀功,提高循环的热力完善度,增加制冷机的COP。通过总结目前这方面的研究,理论分析和计算了蒸汽压缩式制冷循环中应用膨胀机的可行性好经济性,同时给出了一种简单的基于膨胀比的经济性分析方法。By using expander instead of throttling valve in compression refrigeration system, irreversible loss can be reduced and some expansion work can be recovered. So the refrigeration＇s thermodynamical perfectness and coefficient of performance are improved. This paper summaries researches about this and analyze the feasibility of combining expander and compression system, also give a simple economic analysis method based on expansion ratio.
