【摘要】 建立了可逆脉管制冷机的等温－绝热模型，着重考虑脉管中过程对制冷机性能的影响，并与斯特林制冷机等温模型的计算结果进行比较。结果表明，在理想工况下，可逆脉管制冷机的效率约为斯特林制冷机的８５％，制冷量约为７２％。可逆脉管制冷机配气活塞的最佳运动相位与斯特林制冷机基本相同。更多还原

【Abstract】 A isothermal-adiabatic model of the reversible of the reversible pulse tube refrigerator was set up.The effect of the gas process in the pulse tube on the performance was investigated. The compari-son results between the reversible pulse tube cycle and the isothermal Stirling cycle showed thatthe efficiency of the former is about 85%of the latter and the refrigeration power is about 72%.The optimum phase shift of the auxiliary piston in the pulse tube refrigerator is nearly the same asthat of the Stirling refrigerator.更多还原
