摘　　要：目前对HAT循环中回热器的理论分析大多采用传热温差法和表征回热器特性的回热度分析的方法。针对这两种不同的分析方法分别进行了计算,比较分析了它们对HAT循环的影响,结果表明,传热温差法更加适合于对HAT循环进行理论分析,但应当注意传热温差的选取。而回热度法更多应用于回热器的设计。Nowadays two methods are generally adopted for the theoretical analysis of recuperators in a HAT cycle, namely, heat-transfer temperature difference method and thermal-ratio analysis method featuring the characteristics of a recuperator. Calculations were conducted using respectively the above-mentioned two methods of analysis and their impact on the HAT cycle was compared and analyzed. It has been found that the heat-transfer temperature difference method is more suited for the theoretical analysis of the HAT cycle. However, due attention should be paid during the selection of the heat-transfer temperature difference. On the other hand, the thermal ratio method has found more applications for the design of recuperators.
