Özet

© 2016 Elsevier Ltd and International Institute of Refrigeration. All rights reserved.Purpose of this study is to analyze a nano scale thermo-acoustic refrigeration cycle in terms of its thermodynamic performance. A nano scale thermo-acoustic refrigerator operating with Maxwell-Boltzmann gas and He4 is chosen as the working fluid is considered. Thermo-size effects that are dominant at the nano scale are taken into account too. In addition, a new thermo environmental method identified as modified ecological function for the refrigeration cycles is proposed. Considered system are analyzed with this new proposed method as well as basic thermodynamic criteria including COP, cooling load, work input and entropy generation. Results are obtained numerically and presented.
