Brayton refrigeration cycle also be called the quality of gas for the refrigeration cycle .Introduction no reheat about single gas refrigerants cycle, and to theanalysis and calculation.of the ideal cycle.Including the calculationunit volume, unit heat load calculation,the coefficient of performance computing. Introduced the constant pressure to hot gas refrigeration cycle,to the analysis of the theory of the system map and the map of the TS theoretical. To the analysis and calculation of the constant pressure of the refrigeration coefficient gas refrigeration cycle and the coefficient of performance.Find out that under the conditions of constant temperature heat soure, the characteristics of the power density of actual Brayton cycle.Key words: Brayton cycle paramete refrigeration theoretical parameters power density目录中文摘要......................................................................i英文摘要.....................................................................ii目录........................................................................iii第一章 绪论 .................................................................1 1.1 选题背景与意义.......................................................1 1.2 研究目的.............................................................3第二章 布雷顿循环参数计算....................................................4 2.1 逆卡诺循环 .........................................................4 2.2 布雷顿制冷循环参数计算 ..............................................4 2.2.1 等熵膨胀循环 ..................................................4 2.2.2 气体制冷循环参数的计算与分析 ..................................6第三章 燃气轮机循环的热效率的计算与分析 ....................................11 3.1 不带回热的燃气轮机循环..............................................11 3.2 带回热燃气轮机循环 .................................................12第四章 总结.................................................................14致谢.........................................................................15参考文献.....................................................................16 |
