The invention provides a pipeline silencing device and application, and relates to the technical field of air conditioners. The silencer comprises an expansion type silencer and a Helmholtz resonance silencer, the Helmholtz resonance silencer is provided with a closed cavity and a connecting pipe, and the cavity is communicated with the expansion type silencer through the connecting pipe. The expansion type silencer and the Helmholtz resonance silencer are combined, and the good low-frequency silencing characteristic can be obtained within the length size limiting range of a traditional expansion type silencer and the size range of an existing machine or device. According to the composite silencing structure, the mode that the expansion cavity silencer and the helmholtz resonance silencer are combined is adopted, the advantages of the two silencers are integrated, low-frequency precise silencing can be achieved, and the broadband silencing characteristic is achieved. 本发明提供了一种管路消声装置及应用，涉及空调技术领域。其包括膨胀式消声器和亥姆霍兹共
