- Abstract:
- An optimal design method for an aircraft low-power thermoelectric refrigeration system(TRS)is proposed using an existing experimental model as the research platform under given aircraft flight conditions.The variation curves of the cooling capacities and the refrigeration coefficients of the system running at three flight altitudes are investigated.The performance of the system is evaluated by the minimum-entropy-generation method and the performance penalty is also calculated.The power variation curves of the cooling system are obtained by an electric power experiment.The peak values of these curves are less than the maximal electric power supply of airborne equipment, proving that the use of the low-power TRS for airborne equipment is feasible.The COP, cooling capacity and entropy generation of the system are relative to the flight altitude and the current of the TRS.Through the analyses of these data, the optimal values of the COP are obtained, and the optimization measures are proposed to maximize the use of the advantages of the TRS.
- 在设定飞机参数的条件下, 以现有的实验模型为研究平台, 提出了一种机载小功率热电制冷系统的设计优化方法.考察了该系统在3种不同飞行高度运行时制冷量与制冷系数的变化曲线.然后, 利用熵产最小法评估了系统的性能, 并计算出系统的代偿损失.通过电功率实验, 得出了制冷系统的功耗变化曲线, 其峰值小于机载装备可提供的最大电量, 由此证明了小功率热电制冷系统应用于机载设备的可行性.制冷系数、制冷量及系统熵产与飞行高度和电流有关, 通过分析这些变化数据, 得出工作状态下制冷系数的最优值, 并提出可最大程度利用热电制冷系统优势的优化方案.
