| Abstract: | Motion model of compressor driven by miniature moving magnet linear motor was set up.The comparison between the experimental data and numerical analysis verified the effectiveness of this model.A performance factor of 13.0N/A was achieved and the ideal COP reached 78%.The prototype of Stirling refrigerator was formed by integrating linear compressor with pneumatic expander which had a 10mm cold finger.The optimal operating point was found: frequency 48—50Hz、COP of motor 71%. |
