Accelerated life test and analysis on refrigeration pipeline of air conditioners
Excessive local stress in the refrigeration pipeline of air conditioners can lead to cracks in the copper tubes or welds,resulting in refrigerant leakage.An electromag-netic vibration table is used to simulate the excitation from the compressor,and an accler-ated life test is conducted on the refrigeration pipeline.By combining life analysis on the refrigeration pipeline,the vibration stress limit for the refrigeration pipeline in actual products is determined.
