Among them, the pressure pulse caused by the periodic exhaust of the compressor is an important noise source. When the compressor is running, the pressure of the refrigerant in the pipeline system excites the pipeline system at a certain frequency to produce pulsating noise. The pulsating noise caused by pipeline excitation cannot be reduced by damping and shock reduction. It can only be eliminated or weakened by optimizing the design of the pipeline system or selecting a suitable muffler. Therefore, the welding quality of the muffler is particularly important.
