Abstract: | This study presents a reliability evaluation method of the scroll compressor for system air conditioner. After conducting reliability target determination and failure analysis (failure mode and effect analysis) on the scroll compressor, the significance of the stress factors affecting wear (main failure mode) is evaluated using design of experiments. Specifically, wear is estimated under various test conditions using analysis results. The lifetime of the scroll compressor is estimated using the data of zero-failure accelerated life test performed under various test conditions. The result satisfies the warranty lifetime of the scroll compressor. Finally, the procedure of reliability determination test for the scroll compressor is briefly proposed. |
