【Abstract】 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更多还原
