| Abstract: | Based on the irreversible Brayton refrigeration cycle model, the satisfied equation about the optimal relation between the cooling rate and the coefficient of performance is derived. By using numerical solutions, the influence of the internal irreversibility and the heat transfer irreversibility on the optimal performance of the cycle is investigated. Several optimal performances of the cycle are discussed. The results obtained will be helpful to the optimal design of the practical refrigeration system. |
