Study on Wave Rotors Refrigerator
As a novel generation of rotational gas wave machine, wave rotor refrigerator (WRR) is an unsteady flow device used for refrigeration in whose passages pressured streams directly contact and exchange the energy due to the movement of pressure waves. In this work, the working procedure and refrigeration principle are investigated based on one-dimensional unsteady flow theory. A basic limitation on main structural parameters and operating parameters is deduced and then the wave diagram of WWR is sketched, as can guide design. Most main influencing factors are studied by experiment. In DUT Gas Wave Refrigeration Studying and Development Center (GWRSDC) lab the isentropic efficiency now can get 65%. The results show that WWR is a feasible and promising technology in pressured gas refrigeration cases.
