摘要
基于理想费米气体的状态方程 ,建立以理想费米气体3 He为工质的布雷顿制冷循环模型 ,导出循环的输入功、制冷系数和制冷量等重要参数的普遍表达式。对几种有趣的情况作了详细的讨论。
The model of a Brayton refrigeration cycle using an ideal Fermi gas 3 He as the working substance is established based on the equation of state of an ideal Fermi gas The universal expressions of several important parameters,such as the work input, coefficient of performance, refrigeration load of the cycle,are derived Some interesting cases are discussed in detail The bound of the pressure ratio that the Brayton refrigeration cycle can be operated normally is determined
