 摘    要
布雷頓循環使用等熵壓縮,等熵膨脹, 計算分析其理論循環的參數。布雷頓制冷循環又稱氣體制冷機循環，是以氣體為工質的制冷循環。研究單一氣體無回熱氣體制冷機循環，并對其理論循環的性能進行了分析與計算。包括單位制冷量，單位熱負荷的計算和性能系數的計算。對定壓回熱氣體制冷循環進行了系統圖和理論T-S圖的理論分析，對定壓回熱氣體制冷循環的制冷系數及性能系數進行了分析與計算。計算分析了使用布雷頓循環的燃氣輪機循環的熱效率。

Abstract
 
Brayton cycle,the use of entropy compression, such as expansion of entropy.Analysis the theoretical parameters of the Brayton cycle. 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.
