摘      要：As a novel generation of a rotational gas wave machine,the wave rotor refrigerator(WRR)is an unsteadyflow device used for refrigeration,in whose passages pressured streams directly contact and exchange energy due to the movement of pressure *** this paper,the working mechanism and refrigeration principle are inves-tigated based on the one-dimensional unsteadyflow theory.A basic limitation on main structural parameters and operating parameters is deduced and the wave diagram of WRR to guide designing is *** main influential factors are studied through an *** the DUT Gas Wave Refrigeration Studying and Development Center(GWRSDC)lab,the isentropic efficiency can now reach about 65%.The results show that the WRR is a feasible and promising technology in pressured gas refrigeration cases.
