Description

Technical Field

[0001] The utility model belongs to the technical field of mufflers, and in particular relates to a muffler for refrigeration equipment. Background Art

[0002] A silencer is a component used in a refrigeration system that allows airflow to pass through and effectively reduces noise. The air conditioners currently sold and used in the domestic market generally use capillaries or electronic expansion valves as throttling elements. In the air conditioner refrigeration system, when the compressor is running, the refrigerant flows through the throttling element in the system pipeline, and the pressure of the refrigerant after throttling will be reduced to about 0.6 to 1.0Mpa. The throttled refrigerant will expand its volume rapidly, which will correspondingly cause violent gas vibrations caused by the refrigerant in the system pipeline, causing a high decibel noise, thereby significantly increasing the noise in the user's indoor environment. Adding a silencer to reduce the noise caused by the refrigerant is a technical solution commonly adopted by air conditioner manufacturers.

[0003] On November 24, 2022, the applicant applied for a utility model patent entitled A double stainless steel silencer (authorization announcement number: CN219037060U). In this patent, a silencer pipe is provided on the first silencer, and the silencer pipe is connected to the second silencer through a connecting pipe. The connecting pipe is provided with a corrugated section. Through the design of the corrugated section on the connecting pipe, not only the connection stability between the first silencer and the second silencer is improved, but also the silencer effect is improved in conjunction with the silencer pipe. At the same time, it can reduce rigidity, reduce resonance, and increase life, which is convenient for assembly.

[0004] However, when the above-mentioned patent is in use, since the connecting pipe, the silencer pipe and the second silencer are welded together, when individual components of the silencer are damaged and need to be replaced after long-term use, it is inconvenient to replace the individual components, resulting in maintenance difficulties and increased maintenance costs.
