Problems solved by technology

During the operation of the air conditioner, the noise generated by the pulsating air flow is mostly medium and high frequency noise. This muffler is not ideal for reducing the noise of the pulsating air flow, so the effect of a single resistance muffler cannot fully meet the actual needs

Abstract

The invention discloses a silencer for an air conditioner and the air conditioner with the same. The silencer comprises a first silencing cavity, an air inlet pipe, a second silencing cavity, an air outlet pipe and sound absorption materials, wherein opposite side walls of the first silencing cavity are provided with a first port and a second port, the air inlet pipe is inserted into the first silencing cavity through the first port and is of a semi-closed structure, the second silencing cavity is arranged on the first silencing cavity, one end of the air outlet pipe extends into the first silencing cavity through the second port while the other end of the air outlet pipe penetrates through the second silencing cavity, the pipe body of the air outlet pipe located on the second silencing cavity is provided with a plurality of second through holes, and a cavity defined by the outer wall of the air outlet pipe and the inner wall of the second silencing cavity is filled with the sound absorption materials. The silencer for the air conditioner is an impedance compound silencer, and has the advantages of being wider in silencing frequency band and higher in silencing amount.

Description

technical field [0001] The invention relates to a muffler for an air conditioner and an air conditioner with the same. Background technique [0002] The muffler for the air conditioner is to eliminate the airflow noise generated by the pulsating airflow in the pipeline during the operation of the compressor. At present, the mufflers commonly used in air conditioners are generally resistant mufflers, which use the acoustic reflection of the device at the sudden change in the acoustic performance of the pipeline, and use the sudden expansion and contraction of the pipeline section to generate an acoustic impedance mismatch, so that the sound waves of certain frequencies are in the acoustic impedance. Reflection, interference and other phenomena occur at the abrupt interface, and the sound waves cancel each other to achieve the purpose of noise reduction. [0003] At present, the muffler commonly used in air conditioners is a single-section expansion muffler. Due to cost and p...
