Summary
Compared with double inlet type two-stage pulse tube refrigerator, step displacer type has higher efficiency. The step displacer has two functions, input power distribution function and phase shifting function, which are fundamental issues of this type refrigerator. The two functions are discussed by an ideal model, and are investigated by a numerical simulation. Theoretically, the exergy flow ratio to the first stage over the second stage depends on the refrigeration temperature ratio and step ratio, the dead volume at the hot end of the pulse tube can be an additional parameter for adjusting the phase angle difference at the cold end of the regenerator.
