High frequency noise identification and optimization of refrigerator compressor
At present,the high-frequency noise problem of refrigerator compressor is prominent,and the poor hearing of high-frequency noise is easy to cause user complaints.It is urgent to identify the high-frequency noise problem of refrigerator compressor and optimize it.In view of the high-frequency noise problems that are easy to occur in the current refrigerator compressor,takes a certain type of fixed-speed compressor as an example to study the noise source and transmission path.The high-frequency noise problems such as 2500 Hz,4000 Hz and 5000 Hz of a certain type of fixed-speed compressor are deeply analyzed and optimized.The test results show that the optimization scheme can significantly improve the high-frequency noise problem,which provides relevant ideas and theoretical basis for the improvement of the high-frequency noise problem of the refrigerator compressor,and has certain guiding significance for the subsequent product design.
