The working process of the silencer of the invention is as follows: the air flow containing the refrigerant enters the right muffling chamber 22 through the inlet pipe 13, is blocked by the partition plate 30, flows along the arc-shaped surface of the partition plate 30, flows into the left muffling chamber 21 from the communication pipe 31, and is then discharged from the outlet pipe 14. Through the technical scheme, the cavity of the shell is divided into two silencing chambers, namely the left silencing chamber 21 and the right silencing chamber 22, by the partition plate 30, the two silencing chambers are mutually communicated through the communicating pipe 31 on the partition plate 30, and in the air suction process of the compressor, the silencing chambers and the communicating pipe 31 play a good role in guiding the flow direction of the refrigerant, so that the generation of vortex when the refrigerant flows can be effectively reduced, the flow resistance and the pressure loss of the refrigerant are reduced, the noise of the compressor is effectively reduced, and the overall performance of the compressor is ensured.
