摘要
以机载热电制冷模块为研究平台,在已设定飞机参数的条件下,以工作电流为变量,得出了此系统在三种不同飞行高度下工作时的制冷量、制冷系数的变化曲线,利用熵产最小法进行了系统性能的评估,并计算了系统的代偿损失。所作工作为开展机载小功率热电制冷系统研究提供了初步理论指导,具有一定的参考意义。
In this paper,an airborne thermoelectric-refrigeration system is used as a platform for study.By setting the plane parameters,the variations of the cooling capacity and the refrigeration coefficient with the working current for three flying altitudes are obtained.The performance is evaluated with the entropy-generation-analysis and compensable loss methods.The present work sets an preliminary basis for the applied research of airborne small power thermoelectric-refrigeration system and has some reference value.
