Thermodynamic analysis of the basic pulse-tube refrigerator.

Type of article: Article

Summary

The refrigerator is modelled as a tube with one end closed and with a movable piston at the other end. Both ends contain heat exchangers. The thermodynamic model consists of four steps: adiabatic compression of the gas in the pulse tube; isobaric heat transfer from the gas to the wall of the pulse tube; adiabatic expansion of the gas in the pulse tube; and isobaric heat transfer from the wall of the pulse tube to the gas. Results are presented for the COP and the heat removed per cycle as a function of the temperature ratio of the heat exchangers, for various values of the pressure ratio and the non-dimensional length of the heat exchanger at the closed end.
