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.

Key words:  Brayton cycle  paramete  refrigeration  theoretical parameters  power density
