评价制冷装置效率的新概念新方法的探讨

Discussion about the Valuation of the New Concept and Method of Frigorific Device Efficiency

分析了制冷装置效率与熵产之间的关系，介绍了新概念——熵增大率（ＥＡＣ），从地球温暖化的环保本质不是“能”问题而是熵产问题的观点出发，推导、分析、评论了ＥＡＣ作为衡量制冷装置效率指标的科学性、合理性和实用性。

In this paper, the relation of efficiency and entropy production is analysed and a new concept entropy amplification coefficient ( EAC ) is introduced. The nature of the environmental protection problem caused by the earths getting warmer results from entropy production instead of “energy”. From this point of view, EAC can be used as the efficient index of frigorific devices and its scientific and reasonable and practical quality is demonstrated. Therefore, using EAC as the efficient index to discuss the refrigerating system is proposed in this paper.
